Long-burning wood stoves. How to make a long-burning wood-burning stove for your home Long-burning stove for small rooms

In the process of selecting a frame project country house I was faced with the question: which stove should I choose for my home? Due to the fact that a budget option for the house and all systems was being considered, the stoves were discarded immediately, because they involve pouring a separate one, searching for an experienced stove maker and paying for his work. Thus, the cost of just laying (working) a simple brick oven starts from 50,000 rubles. (early 2016). Of course, a brick stove has its advantages, and there are quite a few of them, however, due to the fact that the house was not planned for permanent residence, at the family council it was decided to pay attention to the stoves long burning. Let's try to figure out how to choose a long-burning stove for your home.

What is a "long-burning oven"

In an ordinary brick oven heated with wood, they burn out in two to three hours. The room does not warm up very quickly (after all, a significant part of the heat goes to heating the bricks), but it cools down just as slowly after the combustion stops due to the significant total heat capacity of the stove design. In addition, some of the heat goes into the chimney.

Long-burning heating stoves are made of cast iron or steel (sheet thickness 3-6 mm), so they cool down very quickly after the combustion stops. However, this drawback is eliminated by the operating principle of such furnaces.

The design of long-burning stoves differs from conventional stoves - their firebox is divided into two parts and is more spacious. Some models have an air convection system or a water heat exchanger. The main feature of these heating devices is the ability to operate in two modes:

1. The kindling mode is used when it is necessary to quickly heat the room (the damper opens completely, the ash pan extends a few centimeters, which ensures an influx of oxygen sufficient for intensive combustion).
2. The long burning mode is designed to maintain the temperature at the same level. Firewood burns very slowly, with little oxygen and at a higher temperature than a conventional stove. Such specific conditions are created by loading a large volume of fuel and limiting the flow of air (gate and blower). The firewood does not burn, but smolders, and only a small part.

Due to the design features, the efficiency of a long-burning stove is much higher than that of a conventional one. Therefore, from each stack of firewood you can get heat that will be released for quite a long time.

Advantages and disadvantages of long-burning stoves

Advantages of long-burning stoves:

• compact size and light weight, not requiring the construction of a foundation;
• Efficiency 75-85%;
• long burning time of one filling (up to 10 hours), which provides savings and reduces fuel consumption;
• can be installed in any room that has a chimney;
• relatively light weight, which ensures mobility of the stove (two people can move the stove to another room);
• attractive appearance allows you to combine such a heating device with almost any interior;
• relatively low cost;
• affordable and environmentally friendly fuel that does not pollute the environment.

• Disadvantages of long-burning stoves:

• inability to use liquid fuel;
• quite complex setting of the long burning mode;
• increased requirements for the chimney (the pipe should not be curved due to low draft);
• formation of soot and condensation in the chimney (gases enter the chimney at a low temperature, which contributes to the formation of condensation);
• Constant supervision is required.

It should be noted that the chimney of such stoves must be collapsible (it is necessary to clean the chimney relatively often - approximately 2 times a year). In addition, it is necessary to provide the space around the stove with fire protection: in wooden house under the stove it is necessary to lay a covering of non-combustible material (cement, tiled floor or metal sheet), and the distance from the stove to the wall should not be less than 0.5 m. The heating device can be installed closer to the wall if a non-combustible finish is installed on the wall.

Due to the fact that in the long-term burning mode the flame intensity is low, carbon monoxide is formed in the furnace at this time. During normal operation of stoves in long-term burning mode, this gas does not enter the room, however, following the principle of “God saves with care,” it would not hurt to purchase and install a carbon monoxide sensor in the room with the stove.

Choosing a long-burning stove for a country house

Based on the size of the house, the stove should heat no more than 250 m3 (taking into account the recommended 30% reserve). From the stoves I reviewed on the Internet, I selected two options: Engineer (Professor Butakov) and Fire-Battery 11 (Thermofor). On average, stoves produced by Termofor are no more expensive than 3,000 rubles.

IMPORTANT! The boilers are suitable only for smoldering mode (slow burning). It is not allowed to heat the heat-transmitting surfaces - the body and convective pipes - above 350 0 C! This means that long-term intense combustion is contraindicated for these boilers: it will lead to its rapid failure).

The stove is a traditional attribute of a private home. Despite the presence of full-fledged central or autonomous heating, many owners do not refuse it today. Indeed, they are a good help in the autumn or spring, when the main heating is already turned off or it is too early to turn it on. In addition, with the help of these devices you can not only decorate the interior of the room, but also create in it, if desired. special atmosphere for relaxation or for romantic evening. study at the link.

We have to admit that even today not all Russian private houses are connected to gas mains. And you have to heat the house either with electricity, which is quite expensive, or with solid fuel, which is quite troublesome. Therefore, a stove capable of maintaining heat in a room for 8-12 hours will never be superfluous. This can be achieved by erecting a massive brick structure with its significantly high heat capacity. However, not every area of ​​the house allows the construction of such a heating structure. In this regard, manufacturers have developed designs of compact sizes that can be placed even in the most small room. And the duration of the required heat transfer on one stack of firewood is ensured by their special combustion mode.

Operation of long-burning furnaces

Long-burning stoves are more efficient and economical compared to units of the same size, but having a traditional design. This is due to the fact that they are able to heat a house from one stack of firewood for much longer than the latter. In order to understand the principle of operation of these devices and subsequently operate one of them, as they say, with knowledge of the matter, it is worth considering the design in more detail.

The operation of long-burning furnaces is carried out on the principle of afterburning pyrolysis gases. Therefore, fuel is added to the device less frequently, burns completely, and the stove releases heat much longer.

Pyrolysis is a process in which the fuel in the fuel chamber decomposes under the influence of high temperature in the almost complete absence of oxygen. During this process, the so-called pyrolysis gas is released, which has a very impressive energy potential.

To create such conditions in the firebox, after active combustion of the fuel occurs, the door of the primary air supply chamber (blower) is tightly closed. Thus, the draft inside the fuel chamber is reduced to a minimum. In the absence of air, firewood combustion enters the smoldering stage with the release of pyrolysis gas. Thus, the wood decomposes completely, leaving a minimal amount of ash.

The gas released during smoldering, containing methane and carbon monoxide, enters the afterburning chamber, which can be located in the upper or lower part of the furnace. The required amount of secondary air is supplied to this section of the heating device, under the influence of which the gas ignites and burns, giving high heat transfer. Along with the gases, the soot that rises with them burns out almost completely. The gaseous waste from this combustion is discharged into the chimney.

When burned, the gas mixture produces a bright white flame. This suggests that, under the influence of secondary air, the substances released by the fuel burn out.

Thus, the fuel, essentially burning twice, increases the efficiency of the stove and is consumed over a long period of time. In conventional stoves, all wood combustion products are immediately released into the atmosphere. That is, a significant part of the energy potential contained in the fuel is simply wasted literally “down the drain.”

To understand the process of functioning of a long-burning furnace, you can consider it step by step:

• The fuel chamber is completely filled with firewood. It should be noted that ignition of long-burning stoves may vary. In some models it is done on top of the wood pile. Thus, smoldering spreads from the upper logs, gradually falling down. Thick logs are placed in the lower part of the space, and on top of them are thin wood chips, necessary for quick ignition. In this case, the firewood must be dry, since wet wood does not burn well and gives insufficient heat transfer. Therefore, the operation of the furnace will be ineffective.

In other models, on the contrary, the primary combustion of the wood stash is organized from the bottom up. That is, as the logs burn from below, the remaining stack gradually falls into the smoldering zone. Conveniently, the firewood located on top undergoes the necessary drying and heating to optimal temperatures for primary oxygen-free combustion.

• The next step is to set fire to thin wood chips using paper.

• When igniting, the doors of the ash chamber and combustion chamber must be wide open. Before putting the firewood into a smoldering state, it must burn well. After the fire starts, the combustion door closes, since the temperature in the chamber should reach 270÷300 degrees. In this case, the blower door is closed so that only a small gap remains for a certain minimum amount of air to enter the chamber, sufficient to maintain the smoldering process of the wood.
• Proper operation of the stove is the key to its performance. If the firewood is stacked appropriately and the air flow is adjusted correctly, the stove can heat the room for 8-12 hours from one stack of wood. So, if the stove is lit in the evening, the rooms will be warm until the morning. Then, if necessary, the next addition of fuel is made, intended for daytime heating.

That is, in fact, even continuous operation of the stove will be limited to just two stacks of firewood per day. And in some models the working time from one bookmark is even longer.

Design of long-burning heating stoves

Long-burning stoves come in two designs - with and without a water circuit. Appliances such as stoves are purchased to heat a house with a fairly large area that needs to be heated from one stove.

The device is connected to the heating circuit pipe distribution with installed radiators, spaced apart different rooms. It is clear that if you purchase a stove model with a water circuit, its installation will cost more, taking into account the additional system elements necessary to create an efficient heating circuit. However, owners can count on subsequent cost savings, since the entire house will be heated from one stove.

Conventional long-burning stoves that do not have a water circuit are also capable of heating fairly large areas, but most often within one room. In the best case, two adjacent ones, if the design of the stove allows its installation into a wall.

The manufacturer always indicates the capabilities of the furnaces in the passport and technical description. Therefore, before purchasing a heating device, you should very carefully study its characteristics and compare them with the areas of the premises that you plan to heat.

Oven without water circuit

Long-burning heating devices operate on the same principle and have similar designs. Their difference may lie in the location of the afterburning chamber and the design of the deflector, which may consist of one or more plates. The structure of the device with an afterburning chamber located in the upper part of the structure may look like this:

1. Combustion chamber for storing fuel. In a long-burning design, this section has a much larger volume than in a conventional stove.
2. The window for supplying primary air when the furnace is ignited, otherwise called the ash pan.
3. Afterburning chamber for pyrolysis gases formed during smoldering firewood.
4. A deflector separating the combustion chamber and the afterburner.
5. Branch pipe for connecting the chimney pipe.
6. A door with heat-resistant glass equipped with an air blower that separates it from the fire.

Blue arrows show air flows coming from outside and “working” differently inside the furnace structure:

a) The movement of primary air necessary for igniting firewood and maintaining its smoldering.

b) Movement of secondary air supplied to the afterburning chamber of pyrolysis gases.

c) The flow of air blowing on the door glass, passing along it from the inside and preventing it from overheating and sooting.

Orange arrow – movement of pyrolysis gas.

The purple arrow is the final discharge of combustion products of pyrolysis gas into the chimney.

Heating device with water circuit.

The design of a furnace with a water circuit, intended for heating several rooms, is more complex. It includes heat exchanger elements for heating the coolant and then feeding it into the heating circuit laid throughout the rooms of the house.

One example is shown in the figure below:

1. Furnace combustion chamber. The diagram shows how full the chamber of a long-burning furnace should be with fuel.
2. A section of the water circuit located along the walls of the combustion chamber.
3. A grate assembled from pipes, which are also part of the water circuit.
4. The firebox door through which fuel is added.
5. Door for bottom ignition of fuel filler.
6. Blower door, which is used to regulate the supply of primary air.
7. Door for supplying secondary air to the afterburning chamber of pyrolysis gases.
8. Ash pit.
9. The chimney pipe to which the chimney pipe is mounted.
10. Branch pipe (flange) for connecting the return pipe of the heating circuit.
11. Output (flange) for connecting the heating circuit supply pipe.
12. Furnace body with a layer of thermal insulation.
13. An additional heat exchanger that protects the oven from overheating.
14. Everything indicated in blue is the water circuit of the furnace.

Increasing the efficiency of the furnace and the duration of its operation on one tab

Furnaces go on sale configured for a specific operating mode. As a rule, devices are configured for gentle operation. However, the manufacturer cannot foresee in what specific conditions the stove will be operated and what fuel the consumer will use. So the oven’s capabilities are much wider than the factory settings. In some cases, it will be correct to reconfigure the device to higher or, conversely, lower power.

Changing the oven settings to a suitable operating mode will be optimal in the following cases:

• If during operation of the device the intensity of firewood combustion is too high, and the bookmark burns out in three to four hours. And even when using dry, high-quality firewood.
• The fuel does not burn out completely, that is, after the filling burns out, undecomposed parts of the wood remain.

If these shortcomings are discovered during operation, it means that the oven settings require adjustment. Otherwise, the device will not work at full capacity, not giving the expected effect.

You should not attempt to reconfigure the unit yourself, as you can make the situation worse by knocking down old parameters and incorrectly setting new parameters. The adjustment process should be carried out by a specialist who understands the essence of the problem and knows how to eliminate it.

Types of long-burning stoves

Differences in functionality and general parameters

Compact, having beautiful design Long-burning metal stoves are very popular. Therefore, manufacturing companies have developed entire lines of devices with different sets of functions. Thanks to this you can choose suitable model, depending on the planned location of its installation and intended use.

On sale you can find long-burning stoves with different functions:

• Heating and cooking appliances always have a hob, and some models are equipped with an oven and even a container for heating water.
• Heating options for stoves are used only for heating the house. Such devices can be equipped with a water circuit and used to heat several rooms in the house.
• Heating stoves equipped only with a water heating tank.
• Multifunctional versions of devices, that is, having a complex of all the above functions.

In addition to functionality, when choosing a stove, you need to pay attention to its other parameters:

• The power of the device is selected depending on the heated area.

The table below shows the required indicators of the thermal power of the furnace for a certain heated area:

• The linear dimensions of the stove are selected depending on the area of ​​the room allocated for its installation.
• Installation location - in the corner of the room or near the wall.
• The design of the model is matched to the main design of the room.
• Another point that needs to be taken into account is the material used to make the device. Furnaces can be steel, cast iron, or combined - steel with cast iron elements.

The manufacturer indicates all of the above parameters in the passport, which is attached to the heating device.

Differences in furnaces depending on the location of their installation

Separately, it is worth highlighting a section for describing the types of furnaces according to their location.

You can find two types of stoves on sale - corner ones and those installed near a flat area of ​​the wall, that is, wall-mounted, for example.

• Corner stoves are compact, so you can allocate a corner for them in a small room. Most often, models with this shape are produced in combined version- their body is made of high-quality steel, and the elements in contact with an open flame are made of cast iron.

Corner appliances are usually not equipped with a large number functions, simply because of its modest size. They are mainly intended for heating one room, and the presence of a small heated platform in the upper part of the structure allows you to heat a kettle or brew coffee.

• Wall-mounted stoves are more popular, despite the fact that they are larger in size than corner stoves. The dimensions of devices of this type may vary, depending on the functions provided. Power can also be selected for a specific area.

If you purchase a multifunctional oven with a water circuit, then it is most convenient to install it in the kitchen. Thus, you can use the device both for cooking and heating the entire house. It is noteworthy that a stove with a modern design will not spoil the interior of a living room, and sometimes can become its main decorative element.

Some stove models are lined with ceramics, which also performs certain functions:

— Ceramic plates have a thermal conductivity coefficient that is not as high as that of metal, so they do not heat up to critically high temperatures. This significantly increases the overall operating safety of the device.

— Ceramics, due to their significantly high heat capacity, retain heat well, and therefore serve as a kind of heat accumulator. Thanks to this, the stove cools down for a long time and transfers heat to the room;

— Ceramics also play a decorative role, as they can have different colors and relief patterns. Sometimes it imitates tiles with patterns applied to the surface.

Advantages and disadvantages of long-burning stoves

Long-burning devices are increasingly being replaced in private and country houses old massive brick ovens occupying an excessively large area. However, this type of heating units has not only its “pros”, but also its “cons”. You also need to know about them so as not to encounter difficulties already during operation of the furnace.

Benefits Long-burning devices can be called their following qualities:

• High efficiency. With correctly selected power, one stove can provide heat to a private house of several rooms.
• Rapid heating of the premises of a well-insulated house. So, in 30–35 minutes the temperature in the rooms will already be 20–25 degrees.
• Right set parameters enable autonomous operation of the device for 8÷12 hours. That is, having made one bookmark, you don’t have to worry about the combustion process. The battery life also depends on the volume of the combustion chamber.
• The devices are quite easy to use, the supply of primary and secondary air is easily adjusted.
• The stove can be easily installed in a place prepared for it.
• Compact dimensions allow you to easily place the device in rooms with a small area.
• Multifunctional options, along with their compactness, allow you not only to heat the house, but also to cook food and heat water.
• A neat appearance will not spoil the interior design of the room.
• The high safety of the device is noted, guaranteed by the manufacturer, of course, with its correct installation and connection, and compliance with operating requirements.
• Less fuel consumption compared to using conventional stoves.
• Easy to maintain. It is enough to clean the ash pan from combustion products once every three to four days. The chimney system is cleaned of soot deposits once or twice a year - the frequency of this process depends on the intensity of use of the stove. Experts recommend periodic preventive cleaning. To do this, it is enough to burn pre-dried potato peelings or 300÷350 grams of ready-made starch in the firebox.
• Long service life of the device. Manufacturers most often define it at 10 years, but, as has been found in practice, the stove can serve reliably much longer. When using the device for a long time and intensively, it is necessary to periodically check the welds.

Furnaces of this type also have their own flaws , but they can be easily corrected if desired:

• The oven will not function properly if the settings are set correctly. When smoldering or burning, wood will not decompose completely, which means that a sufficient volume of pyrolysis gases will not be formed. They may not ignite, but simply go down the pipe. Therefore, it is very important to establish the operating mode of the heating unit.
• It is necessary to insulate the stove chimney along its entire length, otherwise the device will also not be able to fully perform its functions. Hot combustion products entering a cold pipe will contribute to the formation of condensation, which, in turn, will attract soot deposits. With prolonged use of an uninsulated chimney, deposits on the internal walls will increase, and this will begin to interfere with the removal of combustion products.
• Long-burning stoves require high-quality fuel - the wood used for combustion must be well dried, otherwise pyrolysis may be incomplete. True, in many models with bottom ignition, as shown above, drying of the main volume of fuel is provided by an ascending warm flow from the burning lower layers. But it will still be better with dry wood.
• Many are put off by the high cost of stoves, especially those that are made entirely of cast iron, have decorative cladding, and are equipped with automated control systems. But the high price is well compensated positive qualities unit.

Fuel for pyrolysis furnaces

As mentioned above, important role The quality of the fuel plays a role in the operation of this type of stove. Therefore, it would be useful to say a few words about him.

When preparing wood logs, you must remember that they should have approximately the same length, which depends on the depth of the combustion chamber. The moisture content of firewood should not exceed 20%. Therefore, having placed one load in the stove, you should immediately prepare the next one by bringing firewood into the room.

In addition to firewood, peat briquettes, pellets and even brown coal are used to fire stoves with a pyrolysis design. Other types of coal cannot be used, as they have high energy intensity. Therefore, during intense combustion there is a risk of damage to the steel walls of the firebox. If the stove has a cast iron firebox that is resistant to high temperatures, then you can use any type of coal.

If you decide to heat the stove only with wood, then even the highest quality ones should be stored in a well-ventilated place, under a roof. Before placing them in the firebox, the wood should be dried at room temperature for 24 hours.

Typically, logs for these purposes are placed in a niche provided in many stove models. If it is missing, then a regular basket or metal racks installed next to the stove will be suitable for drying.

Features of installation of metal furnaces

If the installation of the furnace is performed poorly, its operating efficiency and operational safety may be significantly reduced. Therefore, it is necessary to know the nuances of preparation and installation of the device itself.

Installing the stove is not difficult, but when preparing the installation site, it is necessary to take into account the massiveness of the unit and the strength of the base. Naturally, it is very difficult for one person to lift or move such a device, so you will have to invite helpers.

So, the preparatory activities include the following:

• To install a metal stove in a wooden house, when choosing it, you must adhere to the following recommendations:

— the device must have a closed firebox, and its heating should not exceed 400 degrees;

— the chimney pipe should not heat above 85 degrees, so reliable insulation is installed on it, or sandwich pipes are used for installation.

• When determining the installation location of the device, the height of the ceiling, as well as the location of the floor beams, are taken into account. The last point is important if the pipe goes outside through the attic. The chimney must be located at least 150 mm from the attic floor beams. In addition, the penetration must separate the pipe from the combustible elements of the building with a heat-resistant layer at least 120 mm thick.

• Due to the fact that all components for the chimney are usually purchased along with the stove, it is necessary to immediately calculate the height of the pipe, depending on where it exits on the roof. The minimum excesses above the roof are shown in the illustration above. But often stove manufacturers give other, more stringent recommendations for their products, for example, at least 500 mm above the roof ridge, regardless of the point of passage through the roof. This is specified in the technical description of the device.

• In any case, the total height of the chimney pipe (from the combustion chamber to the tip) cannot be less than five meters.

• If the pipe will be led outside through the wall, then the passage must also be insulated with non-flammable material, which will separate the wall from the pipe. For this purpose, special passage blocks are provided.
• For a stove equipped with a water heat exchanger, the necessary calculations of the heating circuit and its components are immediately made.

• The place where you plan to install the stove must be carefully prepared:

If the stove is planned to be installed on a wooden floor, then these must be boards at least 40 mm thick, without any signs of instability. For safety reasons, an asbestos sheet is laid on them, which is covered with a metal sheet 1÷1.5 mm thick. Sometimes they do it differently - they pour a screed of the required size, about 30 mm thick, which is then covered with ceramic tiles.

If there is even the slightest doubt about the load-bearing capacity of the wooden floor, then a concrete base is installed under the stove. To do this, you will have to dismantle a section of the floor and build a reliable foundation-podium.

The walls near the stove must also be insulated with a non-flammable screen. For this purpose, heat-resistant plasterboard (GKLVO), brickwork, ceramic tiles or other heat-resistant materials.

• The device must be installed without distortions, so its installation is carried out with careful control of verticality in terms of level or plumb.
• The connecting joints of the chimney pipe in the room must be sealed. For this purpose, a special heat-resistant sealant is used.
• Pipe joints should not overlap pipe passages through a wall or attic floor.

• A cap is mounted on top of the chimney pipe, which can protect its opening from the ingress of foreign objects, moisture and dust. Such contamination can significantly reduce the efficiency of removal of combustion products.

There are special deflector heads that can not only create the required level of protection for the chimney duct, but also promote normal draft at any wind speed and direction.

A brief overview of popular models of long-burning stoves for a private home

Today, a considerable range of long-burning stoves of various designs are offered for sale, technical specifications and design.

Unlike other models, this stove can use two types of filling the combustion chamber with firewood, since it is equipped with a side door. The manufacturer took into account the shallow depth of the firebox, which is why an additional door was developed through which longer logs can be loaded.

The firebox and oven doors are equipped with heat-resistant panoramic glass, designed to heat up to 750 degrees. It is made of durable glass-ceramic material. Such glazing makes it possible to visually control both the combustion process and the preparation of dishes.

The technical characteristics of this model are presented in the table:

The information provided by the manufacturer supplements the characteristics indicated in the table:

• It is recommended to use firewood, peat briquettes, pellets, and brown coal as fuel.
• The estimated service life of this device is 35 years.
• A gate valve is used to supply primary air. The gate is easily adjustable, so it will not be difficult to set the required traction intensity.
• When operating the stove in long-term burning mode, the outer walls of the stove heat up to a temperature of 80÷85 degrees. Therefore, it is necessary to provide protection to the surfaces around the device.
• The burning time of one stack of firewood is 8÷10 hours

So, in order to choose the right wood stove for heating a house with a certain area, you must first carefully study its characteristics. If you need to heat several rooms from one device, it makes sense to purchase a device with a built-in water circuit.

In Russia, during the cold season, it is impossible to maintain comfortable living conditions in your home without heating. In houses and cottages where it is impossible to connect to a centralized heating system, various stoves are used. Most often they are heated with wood. Wood-burning heating devices can be divided into two large groups: with periodic operation and with long-term burning of fuel (6-10 hours). The second type of furnace is often called gas generator furnace.

Operating principle of a long-burning furnace

In a conventional stove heated with wood, the fuel burns out in two to three hours. The room warms up quickly, but cools down just as quickly after the combustion stops. This means that firewood must be added frequently, which is inconvenient, especially at night. In addition, such a heating device takes oxygen from the room, and part of the heat goes into the chimney.

Heating devices with long burning wood are made of cast iron or steel (sheet thickness 3-6 mm). They differ in design from conventional stoves - the firebox is divided into two parts and more spacious. Some models have an air convection system or a water heat exchanger.

The main feature of these heating devices is the ability to operate in two modes. If it is necessary to quickly heat the room, the damper opens completely, the ash pan extends a few centimeters. The long burning mode is designed to maintain the temperature at the same level.

Firewood burns very slowly, with a small amount of oxygen and at a higher temperature than in a conventional stove.

Such specific conditions are created by loading a large volume of fuel and air restrictions(overlapping gate and blower). The firewood does not burn, but smolders, and only a small part. The main mass only heats up and forms a flammable “fuel” gas, which subsequently also burns, providing the room with heat. Thanks to this design, the efficiency of a long-burning stove is much higher than that of a conventional one. From each stack of firewood you can get much more heat for quite a long time.

Advantages and Disadvantages

Like any product, long-burning heating devices have both advantages and disadvantages. The advantages include:

• compact dimensions and light weight, not requiring foundation construction;
• Efficiency 75−85%;
• one refill can burn for up to 10 hours;
• more economical than traditional heating devices, which reduces fuel consumption;
• You can add firewood to the firebox without interrupting the combustion process;
• All models are equipped with adjustment combustion of gases;
• pellets and coal can be used as fuel;
• cast iron models last up to 50 years (resistant to corrosion);
• can be installed in any room, in which there is a chimney;
• two people can move the stove to another room;
• attractive appearance allows you to combine such a heating device with almost any interior;
• reasonable cost;
• affordable and environmentally friendly fuel that does not pollute the environment.

The disadvantages include:

• inability to use liquid fuel;
• enough complex setup;
• increased requirements for the chimney(the pipe should not be bent due to low draft);
• gases enter the chimney at a low temperature, which contributes to condensation formation;
• required constant supervision.

When purchasing a gas generator stove, instructions are provided. But there are nuances that it does not define. Please note that:

• the chimney must be collapsible (the chimney must be cleaned frequently);
• pipes should be installed according to the movement of gases;
• it is necessary to provide the space around the stove with fire protection.

This means that in a wooden house, a cement or metal sheet must be laid under the stove, and the distance from the door to the wall should not be less than 1.2 m, the distance from the stove to any other wall should not be less than 0.5 m. Closer to The heater can be installed on the wall if there is a barrier installed on the wall.

Popular models of long-burning stoves

The most popular long-burning stoves in our country: Canadian “” and Russian “Breneran” and “Professor Butakov”.

• Buleryan" is made of steel and has a barrel shape. The firebox has two tiers, with air ducts, and there is no ash collector. Air ducts make it possible to heat adjacent rooms.

Buleryan

Canadian heating devices operate in two modes: kindling and long burning. During kindling (about half an hour), the stove and the room warm up, then the second mode is switched on - the firebox is completely filled with firewood, the door closes, and the air flow decreases. One bookmark burns for 10-12 hours. Buleryan requires little firewood, but it must be dry. The use of other types of fuel is not permitted. Inconveniences include the need to insulate the chimney and incomplete combustion of the generator gas.

Breneran

Domestic equipment "Breneran" almost no different from the Canadian “Buleryan”. Aluminum sleeves can be placed on convection pipes to heat adjacent rooms. But the heat loss from such pipes is quite large. Therefore, experts recommend putting a casing on the Breneran, installing a collector and then routing the pipes to adjacent rooms. Collectors and casings are not mass-produced, but custom-made ones are almost identical in cost to the price of the heating device.

The main disadvantage of the Breneran is the smoke pipe with a tee and a condensate collector on the wall. It is almost impossible to make a container-glass airtight, so condensation enters the room.

Brenerans are produced in different sizes, which allows you to choose a stove for a room of any size. Model "Aqua-Breneran" allows you to connect water heating. But cold water cools the gases, the volume of condensate increases, and the long-term combustion time is reduced.

Professor Butakov

The Professor Butakov heating devices are interesting - they are more attractive in appearance than the Brenerans, the firebox is equipped with grates, convection pipes are more efficient, and there is a pipe for connecting to the chimney from above. Condensation flows into the stove and burns. Since there is no condensate collector, pipe cleaning becomes more difficult. It can be cleaned either from above or by moving the heating device. When installing this stove, you should remember this feature and place a pedestal under it, which can be removed during operation and disconnected from the chimney.

Professor Butakov" is produced in different sizes. But longer burning time is shorter than that of “Breneran” due to the grate bars in the firebox.

What to look for when choosing?

When purchasing, the main indicator to consider is power. In addition, the size of the heating device also depends on the power. If you put in small room a large, powerful stove will take up a lot of space, the air temperature will be too high, and the wood will be burned in vain. A small, low-power device in a large room will have to be used to the limit, which will most likely damage it.

The choice of long-burning stoves is quite large, so it is possible to choose a device for a room of any size.

Every house needs heating during long frosty winters. It would be impossible to live in a house without heat. Anyone who wants to fill their home with life-giving warmth thinks about how they organize heating. The editors of the site invite you to familiarize yourself with wood-burning stoves, the efficiency of which is 90%. These are the best long-burning wood stoves for your home. We have looked at all the pros and cons of such heating systems and offer to find out what types of long-burning wood stoves are available and how to operate them correctly.

Advantages and disadvantages of long-burning wood-burning stoves

Any unit has disadvantages and advantages; studying such nuances allows you to choose the optimal model for heating your dacha.

Design of long-burning furnaces

Long-burning wood-burning stoves have their own design features. To reduce intense combustion, the air supply is controlled in several ways: upper or lower combustion and pyrolysis of wood. The most common option is top combustion. With this method, firewood smolders from top to bottom to the base of the firebox. The combustion area is limited by the supply of dosed air. Below is a picture explaining the design of a wood stove for long-term burning.

You can see the role played by the supply of cold air, a hot air chamber with a cut-off valve that meteres the supply of oxygen into the combustion chamber. Often such stoves are equipped with a convenient ash pan-scoop.

Operating principle of long-burning furnaces

Let's get acquainted with the operating principle of a long-burning wood-burning heating stove for a country house. The process that occurs in the combustion chamber is called pyrolysis or gas generation. This can be described with the word “smoldering”, since the concentration of supplied oxygen is extremely low, combustion as such does not occur.

So, fuel hard type put in the stove and set on fire. The role of the blower during ignition is important; the damper must be fully open. First, the wood is heated and completely dried. The process of heat transfer and release of flammable gases begins. These gases pass into the upper chamber and burn there. The house should warm up within 30-40 minutes. After this, close the blower damper in order to block the access of oxygen.

At this point, you can add new fuel. The combustion mode at the lower level makes the most useful use of pyrolysis gas. The chemical processes taking place in the bowels of the stove in wood fuel are such that the raw material does not burn, and in the absence of air access it releases pyrolysis gas, ash and other elements. All this combustible mass accumulates at the top of the combustion chamber and transfers heat to the walls of the furnace, to the heat exchanger or convector.

Main technical characteristics of long-burning wood-burning stoves

Like any other device, long-burning stoves have their own technical characteristics:

• power;
• the material from which the firebox is made;
• unit weight;
• external finishing material.

Ovens with hobs

Such additional function Long-burning stoves, like cooking, are pleasantly combined with the overall reliability of the unit. Such equipment will fit perfectly into the kitchen environment, as modern design very diverse. Numerous models presented by manufacturers are easy to transport and install without problems. It is recommended to use only high quality firewood. Otherwise, efficiency decreases. There are some difficulties with lowering the temperature on the metal surface of some units. When choosing a model, it is better to opt for those that have an additional shutter to lower the temperature.

"Breneran"

In Russia, an analogue of the models from Canada that has excellent technical characteristics has been created. Manufacturing is carried out according to European quality standards. Let's look at the Breneran stove models. They go under the names AOT and digital ordinal index. The lower the power, which for the AOT-6 model is 6 kW, and for the AOT-19 model is 35 kW, the less spatial volume the stove can heat. AOT-6 copes with heating 56 m2, and AOT-19 completely heats 260 m2. The number index of Breneran stoves is located in such a way that the lower the serial number, the smaller the weight and heated area.

Sometimes glass doors are included in the package, and you can connect the unit to the water circuit. The disadvantages include condensation entering the room where the stove is located. This occurs due to a lack of tightness on the smoke fitting.

"Vesuvius"

Russian long-burning stove for any premises: country house, bathhouse, garage. Its small size allows it to be used in any outbuilding. You can choose a model based on the requirements of the room. The design of these stoves is such that pipes welded inside the firebox help the passage of hot air, which plays a role in uniform heating of the space.

"Termofor"

What can you say about the domestic development of Termofor stoves? These are several models with interesting names and very compact sizes and a power of 413 kW. The heated space depends on the model and varies from 50 to 250 m3.

"Ermak"

Reliable heating devices with low weight and compact dimensions. Ermak brand stoves have proven themselves well and are installed both in country houses and in residential buildings.

Rules for operating long-burning stoves

When operating any equipment, it is better to adhere to the following rules:

1. Overheating is unacceptable.
2. Pay special attention to units with plastic or metal-plastic pipes. Such ovens should not overheat.
3. Availability supply ventilation Necessarily.
4. No flammable objects on the boiler!

Installing a long-burning stove with your own hands

If you have not opted for any of the designs presented above, then we suggest approaching the issue of heating your home from a different angle. You can make your own wood-burning brick oven for your own home. The Internet is full of drawings brick kilns With the rules, with the help of such homemade units you can successfully heat your house for many years. The drawing below will help you make such a stove yourself.

To install a long-burning stove with your own hands, you will need to take care of a set of pipes for the chimney. Their diameter must match the diameter of the furnace pipe. The method of installing the chimney is vertical or external.

After installing the chimney, the stove is assembled and installed in the chosen location. If necessary, use a special sealant for the fireplace. The most important point there will be a hermetically sealed connection between the stove and chimney structure.

Long-burning wood stoves: prices, where to buy inexpensively

The price range of such heating equipment has a wide range. Selecting and ordering through online suppliers will be the easiest solution. For this purpose, many convenient catalogs have been created, where all the technical characteristics of the unit are indicated; in the photo you can see the nuances appearance and find out about the availability of the stove in the store and delivery methods. If there are representatives of the brands you are interested in in your city, the purchase will be cheaper.

The price of cast iron stoves “Surpa” is on average 120,000–140,000 rubles. Domestic stoves are much cheaper. “Teplodar” and “Termofor” are available at a price of 20,000–30,000 rubles. Vesuvius stoves can be purchased for 10,000 rubles.

The prices of stoves for homes with water heating depend not only on the manufacturer, but also on the supplier. Breneran stoves, model AOT-14, can be purchased for 28,000 rubles. Delivery costs to remote locations will be higher.

Our climate requires maintaining comfortable conditions in homes during the cold season. The heating system must be of high quality, because in some regions heat comes so rarely that there is practically no time left for repairs. Pros stove heating appreciated by our ancestors. Long-burning wood-burning home stoves are common and popular today.

Long-burning home stoves are becoming more and more popular every year. This is due to the fact that solid fuel boilers standard type are uneconomical to use. Oxygen easily penetrates into the combustion chamber, the fuel quickly burns out, and the firebox has to be constantly monitored. For country house This design is suitable, but for a capital one it is not. The old type boiler is being replaced by a modern furnace, where the fuel does not burn, but smolders. The models are used not only for heating private houses. Simple designs are great for heating:

• storage facilities;
• saunas and baths;
• country houses.

In another way, a long-burning stove is called a gas generator or pyrolysis stove. It has a lot of advantages over its analogues. The heating stove operates in two modes:

• combustion;
• smoldering (economy mode).

Operating principle

The slow burning oven consists of two chambers. Firewood is loaded 1-2 times a day. The principle of operation is the process of gas generation, which means smoldering. In the first compartment, fuel is slowly burned, producing pyrolysis gas, which rises into the second chamber and burns. The heat is distributed evenly, slowly, and the stove body remains warm.

At the heart of the heating equipment is a control valve that blocks the access of oxygen during the combustion process to give the “green light” to smoldering. During the process, gases will begin to be released:

• carbon monoxide;
• methane;
• hydrogen.

Once in the second chamber, the gas ignites and releases heat. This is how long-burning wood stoves for homes work. Such devices are made from various metals and alloys, and cast iron products are the highest quality. Their service life is estimated at 50-70 years.

Organize the heating process for wooden house on the basis of a wood-burning stove, long burning is possible, while space for the equipment is provided in advance. It is important to provide basic installation rules in order to prevent fire:

• The stove should be installed away from the walls, first finishing them with a material that prevents heating.
• Even if the structure has legs, we cover the floor with fireproof material.
• It is prohibited to install flammable objects near the stove.

The pyrolysis process inside a solid fuel furnace occurs at a temperature of 600 degrees.

Long-burning heating stoves are installed even in unheated rooms. When you arrive at your dacha in winter, you will quickly heat the room to a comfortable temperature without wasting large number fuel. This will take no more than half an hour.

Advantages and Disadvantages

Long-burning wood stoves have many advantages, which is why they quickly conquered the market. However, we should not forget about the disadvantages. The choice of stove directly depends on the ability to install the equipment and come to terms with the nuances of operation. The advantages are:

• high efficiency of the long-burning furnace reaches 85%;
• wide selection of models, their compact size;
• stoves of this type are economical, fuel is consumed slowly;
• the possibility of combining solid and liquid fuels;
• ease of switching modes and controlling the mechanism.

The disadvantages will help you make sure before choosing that such equipment can be installed in your home, and the operation process will not become problematic:

• a chimney for such a stove must be provided in advance; curved pipes are not suitable for it;
• ready-made models are designed for one type of fuel, they are not universal;
• The chimney of such a stove will have to be cleaned frequently, since the smoldering process involves the release of a large number of combustion products.

Note that the economical smoldering mode can only be started after the house has warmed up to the optimal temperature. Those who want to install this heating device at home will have to choose a ready-made model from those on the market. However, some “homemade” ones are so well made that they can compete in efficiency with factory stoves.

Let's talk about how to make a long-burning stove with your own hands. If you have a diagram on hand and necessary materials, everyone will be able to assemble heating equipment.

Self-production

In order to make a heating device, use any of the available materials:

• refractory brick;
• cast iron;
• steel.

Long-burning stoves made of brick are rare, since this material will not provide the longest possible smoldering process. Depending on the design of the stove, the craftsmen try to achieve the longest fuel combustion possible, up to 12 hours. This factor depends on the amount of oxygen in the combustion chamber - the less it is, the longer the smoldering process.

Homemade long-burning stoves are suitable for heating small country houses and village houses.

Requirements for the work site

To create a long-burning stove, you will need to make your own boiler. Think over and arrange your workplace. The master will need:

• access to the electrical network;
• dry storage room for storing tools and materials;
• free space for work.

In warm sunny weather, work is carried out in the fresh air. It is based on a schematic image (drawing) for the future boiler.

Schemes, necessary tools and materials

To create a high-performance, long-burning solid fuel boiler with your own hands, you need to have some knowledge of how the heating system works. It consists of three parts:

• the area into which fuel is loaded;
• the area where burning and smoldering occurs;
• smoke exhaust area.

The design of a long-burning furnace is simple, the diagram is presented below. Please note that there is an air supply regulator at the top. The better this element is made, the longer the smoldering process takes place.

The design of the furnace may look different:

According to the presented diagrams, we will draw up a drawing of a long-burning furnace on paper and get to work. Tools you will need:

• hammer;
• axe;
• electric welding machine;
• grinder (autogen);
• roulette;
• level;
• black marker.

The materials we use are:

• as a base - a steel or cast iron barrel with a volume of 200 liters without visible damage;
• channels or metal scraps for the legs of a solid fuel stove;
• steel sheet, 5 mm thick - at least 1 m2;
• door for the combustion chamber;
• metal pipe, 100 mm in diameter, 15 cm higher than the barrel.

The chimney is made from a pipe with a diameter of 150 mm. If there is no barrel, it is replaced with a gas cylinder. The base of a stove for a long-burning wood-burning cottage is also made of sheet steel. The thicker the base wall, the longer the service life of the equipment.

The fuel used for such a furnace is:

• firewood;
• coal;
• sawdust and other solid fuels.

The wood stove needs to be cleaned twice a week, leaving a small amount of ash at the bottom. This will protect the bottom from burning out.

Step by step instructions

Step 1. A long-burning wood stove is made from a readily available metal cylinder that has a bottom but no lid. If used gas cylinder, first remove the upper part with a grinder or autogen. The cut level is drawn in advance so that the top is even.

Be careful when cutting the gas cylinder. Before doing this, you need to unscrew the valve and fill the container with water.

If a long-burning wood-burning stove is made of a sheet of steel, then it is not necessary to weld the structure in the form of a cylinder. The cube shape in this case looks more advantageous and will be more stable. If you like a long-burning cylindrical wood stove, limit its height to 1 meter.

Step 2. A pressure circle is made from a sheet of steel. The diameter of the circle should be slightly smaller than the diameter of the cylinder (by 2 centimeters). A circle is cut out in the middle according to the diameter of the pipe (100 mm). It is inserted into the hole and welded. The pressure circle must have free movement, and on the inside it is necessary to weld an impeller or channel in the form of a cross.

Step 3. In the lower part of the base of the structure from which the wood-burning stove for the home is made, a small hole is cut out through which it will be convenient to remove the remaining ash. Having cut the door to size and fastened the hinges, we make the door.

Step 4. Using this principle, a hatch is cut for loading fuel.

Step 5. A long-burning solid fuel stove has a chimney, which is made of a pipe with a diameter of 10 cm. Achieve a strictly horizontal position.

Step 6. The boiler lid is cut from a sheet of steel. A 10 cm hole is made in it for the air distributor. It is important that all parts have a tight fit - this will ensure maximum performance, since oxygen flow will be minimal.

A homemade long-burning wood-burning stove has a simple design, and can be easily improved if desired. A solid fuel stove runs on coal, wood and other fuels. It is important to pack it as tightly as possible into the combustion chamber.

The principle of operation of the boiler is simple: by opening the top cover and removing the air regulator, the owner fills the container with firewood, coal, peat or other combustion products. Lighter fluid is often used to speed up the process. The cover is put in place, the fuel is ignited. At this moment the air damper opens. When the fuel is smoldering, you need to close the damper and enjoy the warmth. Before burning a full tank of fuel, the process is repeated.

Sometimes you can hear the name “top combustion furnace” in relation to this design. The air regulator pipe will gradually decrease into the boiler during operation of the heating system. This indicator will allow you to estimate the amount of fuel in the boiler.

Homemade brick ovens

Long-burning brick stoves are not difficult to build yourself. If you take the issue seriously, you can also cook lunch in such a stove. Brick quickly releases heat, making the room warm. Cooking ovens are still common in the suburbs where people live permanently. This type of long-burning design is rarely used for summer cottages.

An important disadvantage of brick is its rapid cooling. Externally, a long-burning brick stove is no different from a classic Russian stove, but the internal structure of the structure is more complicated, due to which the heat is retained longer.

The diagram indicates the presence of a shaft in the furnace leading to the intermediate hood. Gases burn out in it - this is a mandatory requirement for a long-burning stove. It is difficult to do it yourself without special skills - you will need the help of a professional stove maker.

Brick is a heavy material. This is an additional disadvantage of the future design. Install it on the prepared base. Before a long-burning brick stove is built, we must make a foundation. Ready-made country houses rarely provide for the possibility of erecting such a foundation. The steel stove design shown above is perfect for a summer residence. Long-burning wood-burning stoves made of brick are best used for homes where permanent residence is planned.

Brick wood stoves for heating are demanding in terms of foundation construction: 50 cm underground and another 10 centimeters above its base. Additionally, on each side, the space is increased by 5 cm so that the design
