Boilers of long burning on wood. Heating a private house with a solid fuel wood-burning boiler

Firewood is the most accessible and inexpensive type of fuel in our country. In addition, it is the most environmentally friendly fuel. To maintain the heat output, the manufacturer recommends heating the boiler with coarsely chopped dry logs of various types of wood.

Buy a wood-fired boiler in our store at the price of the Ermak-Stoker manufacturer. The sizes of a fire chamber favorably distinguish our heating devices from analogs. The most inexpensive and budgetary model of the wood-burning boiler AOTV 8-E is designed for logs 50 cm long at a flow rate of 5 kg / hour in long-burning mode. The depth of the furnace of the most productive PRO 32-E unit is 62 cm. Due to the volumetric furnace space of the boilers, a large amount of firewood is possible for autonomous operation in the long-burning mode.

In the conditions of an economical mode of long burning with a minimum air supply, logs of firewood smolder in the boiler furnace, and the emitted wood gases burn in the afterburner. The result of the operation of the device is saving on heating with the maximum duration of the device. Economy mode makes full use of wood fuel reserves, reduces home heating costs and minimizes maintenance.

The heating system is heated through a water jacket, the coolant is distributed over a large heating area around the furnace. For easy control of the water jacket temperature, all models are equipped with thermometers on the front wall of the case.

Useful Options

To avoid temperature fluctuations after burning firewood, the manufacturer recommends buying a heating element with a thermostat for your boiler. This option will automate the heating process and maintain a constant comfortable temperature in the heating circuit. The threaded coupling for the heating element is located in the lower part of the body.

By purchasing a draft regulator for a wood-burning boiler, you can automate the operation of the damper that supplies air to the furnace to control the set temperature of the coolant.

If a loyal price for a wood-burning boiler for heating a private house is of primary importance to you, then you need to pay attention to Russian units. Today, Russian-made products are distinguished not only by their low cost, but also by their reliable operation and long service life.

Firewood, despite the presence of many other types of heating, does not lose its relevance today. Most often, they resort to it in the absence of a gas pipeline. This type of heating is commonly used in rural areas. Quite often, wood heating is used to heat private and country houses, cottages and garages.

Advantages and disadvantages

There are many advantages to heating with wood. The main thing is their low cost. It is lower than the price of gas or electricity. Moreover, even woodworking waste can be used for this type of heating. Moreover, by no means all the settlements of our country are gasified. This is especially true for villages in rural areas. Heating with logs is also great for summer cottages.

An important factor when choosing heating with wood is the environmental friendliness of this fuel and the comfort that it allows you to feel. This is not only warmth, but also visual pleasure from the sight of burning wood in a fireplace or in a stove equipped with a panoramic transparent screen, which is usually built into the fuel loading door.

Heating with wood also has disadvantages. The first is the lack of automation. After all, the fuel will have to be loaded into the stove, boiler or fireplace with your own hands, and this takes a lot of time and effort. In this, heating with logs is significantly inferior to gas and electric heating systems. After all, they can be operated practically without human intervention.

In advance, you will need to take care of the availability of a supply of firewood. You can buy them or make your own. In addition, if the area of ​​\u200b\u200bthe house is large, you will have to additionally use radiators, since it is unlikely that it will be possible to achieve good heating with just a fireplace or stove. Especially in winter. It is best to use a boiler with a water circuit.

Despite the fact that firewood is affordable for everyone, you will need to spend money on installing a stove, boiler or fireplace. And this “pleasure” cannot be called cheap. You will also have to mount all the additional equipment that will be required to heat your home with high quality.

Proper production of wood heating

Modern wood fuel heating systems have significant differences from previously used schemes.

Attention: Brick stoves, which acted as a heat exchanger, transferring the generated heat to the room, were replaced by modern fireplaces, boilers and stoves.

The choice of heating device depends on the availability of space for installation and the area of ​​the building. When choosing a wood heating system, you need to pay attention to the following factors:

1. Thermal power of the device. It depends on the area of ​​the house, the degree of its thermal insulation and the climatic zone in which it is located.
2. The need to allocate space for a boiler or furnace. The device for heating with wood fuel must be installed in a room specially designated for this purpose, which must meet certain requirements. In particular, have stable ventilation.
3. Availability of storage space for fuel. Wood must not be stored in a room where a stove or boiler is located. They must be stored separately.

To determine the device that is best suited for heating with wood, you should take into account the parameters of the building and your financial capabilities. As practice shows, the most popular and effective option is to use a double-circuit boiler with a water circuit in a private house. It will allow not only to warm the building with high quality, but also to always have hot water at hand. But in order to make the final choice in favor of one or another device for heating on wood, you should consider each of them in more detail.

Wood heating options

In order for the house to be warm, you should choose the right wood-burning heating of a country or private house that will be used. As already mentioned, a stove, fireplace or boiler can be used for this purpose.

Attention: When choosing, you should start from the number of rooms and the area of ​​\u200b\u200bthe building.

Usually, if the house is small, a stove or fireplace is installed. Otherwise, it is better to install a boiler with a water circuit. Let's take a closer look at each option:

1. Furnace heating is characterized by high efficiency and a small heating area. But at the same time, it is the easiest to install. Furnace heating is suitable for buildings up to 60 m².
2. Water heating includes a boiler (fireplace, stove) with a pipeline connected to it. Thermal energy is transferred through radiators. This heating option is good for buildings over 80 m².
3. Fireplace heating is in many ways similar to stove heating. The main difference is in a more capacious combustion chamber. In some cases, such a boiler may have a hob.

The heating system using wooden logs can be significantly improved. For example, a heat exchanger can be installed in the furnace, which will allow you to create a full-fledged water heat supply.

But most often, a wood-burning boiler is used to heat the house. It is much easier and more practical to use than a stove or boiler. In addition, it can be made independently.

Making a wood-fired boiler yourself

It's not difficult at all. You just need to choose the right grade of steel. Its thickness must be at least 1.5 mm. The boiler is recommended to be made by welding. But since it takes a lot of time, steel barrels with the desired wall thickness are often used.

It is best if the barrel capacity is 200 liters. It must be cut along, and inside to make a partition. This will be required to install the wheels. A hole is made on the end part for mounting the door, which is recommended to be selected in advance. You will also need a chimney with a diameter of not more than 10 cm. It is located on the reverse side and serves to remove carbon monoxide.

But if you intend to install a heating boiler made by yourself, you should be aware that it has some disadvantages. First of all, it is low efficiency and short service life. In addition, if you accidentally touch its surface, you can get burned, as it gets very hot.

A do-it-yourself wood-fired boiler is perfect for heating various outbuildings with a small area. For example, barn, garage, etc. If you need to heat a country or private house, it is best to install a factory model, which will be of much better quality and will allow you to heat the building well.

Arrangement of the boiler room

Wood burning implies the allocation of a room in which the boiler and devices for its control will be located. This room must meet the following parameters:

• the presence of a smoke channel with a height of at least 4 m;
• area not less than 6 m²;
• the presence of combined lighting;
• ceiling height not less than 2.5 m;
• presence of forced ventilation.

Attention: Room decoration should be made of fire-resistant materials. If the boiler has electrical components, there must be a power supply line.

What kind of firewood is best to use

Much for good heating depends on what kind of firewood you use. It should be taken into account that the specific heat transfer of this type of fuel is much lower than, for example, gas. For firewood, the heat transfer is - a maximum of 17.4 MJ / kg, and for gas - 31.8 MJ / kg. Moreover, to maintain the desired temperature, logs should be regularly thrown into the oven.

There are two ways to increase the time between downloads:

• heating with wood, which emit the most heat;
• installation of a furnace or heat generator with a large combustion chamber.

In the latter case, it should be borne in mind that the volume of the combustion chamber of boilers is much larger than that of furnaces. Also, stoves are characterized by slower heating, during which you will often have to throw firewood. But then, you can enjoy the heat, as the fuel will burn quite intensively and this will be accompanied by a large heat transfer.

Much depends on the wood you use. Ash, hornbeam and oak are distinguished by the greatest heat transfer. Their burning temperature is about 1000 degrees. In addition, they give a strong heat. The worst firewood from poplar. Their combustion temperature is less than 500 degrees, which means that the consumption of firewood will be greater, and the heat transfer will be less.

Attention: Since ash and oak are quite valuable tree species that are used to make various furniture, doors and various other things, it is best to use birch or white acacia for heating your home. Of course, if these types of trees grow in your area.

Much depends on how dry the firewood is. After all, if they are wet, then the heat transfer will be minimal. This is due to the fact that most of the heat generated is required to evaporate moisture. If you buy firewood, you should carefully check its dryness. And if you harvest them yourself, the firewood should be dried well. This is the only way to achieve high-quality heating with a reasonable consumption of firewood.

Do-it-yourself wood-burning heating of a private house allows you not only to save a lot of money, but also to effectively heat the building even in severe frosts. It will not be difficult to make a stove, boiler or fireplace on your own. But it is best to purchase a factory product, as it will be of better quality and will last much longer. Of course, this system is not without some drawbacks and, for example, is inferior to heating with gas or electricity. But still, the demand for wood-burning boilers, stoves and fireplaces is still great. These devices are indispensable for high-quality heating of houses in rural areas in the absence of gas supply there.

With a limited choice of energy sources, there may not be an alternative to wood-fired heating at all. It is important to purchase a suitable wood-burning boiler and understand the features of its operation. We will tell you about these heating units, from choosing the right variety to installation issues.

The main types of wood boilers

The arsenal of heating equipment is constantly updated with new, more advanced products, but nothing radically new has been invented among solid fuel boilers. In an attempt to increase the efficiency, the designers somehow improved the design, which is why several varieties appeared with a number of characteristic features:

1. Complex Z-shaped form of the furnace or its division into 2 combustion chambers. Such boilers are designed for long-term combustion and the most complete combustion of the released pyrolysis gases.

An example of the design of a solid fuel boiler for long burning: 1 - boiler automation; 2 - loading door; 3 - primary air supply; 4 - secondary air supply; 5 - ash pan; 6 - combustion of pyrolysis gases; 7 - pyrolysis of solid fuel; 8 - heat exchanger; 9 - exhaust fan

2. The presence of water-filled grates and / or jackets. It is believed that in this way the coolant takes up to 90% of the heat of combustion, but in practice, good wood-burning boilers with an efficiency above 80% are already a rarity.

3. Form of blowing organization. By reducing the incoming oxygen, the burning time can be greatly extended, maintaining the water temperature within the specified limits. Usually implemented by a manual or controlled damper, if the draft is not strong enough, a boost fan can be used. The damper control is usually performed by digital automation that controls the temperature of the water in the supply pipe.

4. Type and device of the heat exchanger. On the one hand, there is a race for maximizing the surface area for more efficient heat removal, on the other hand, for durability and reliability. In the first case, we have boiler-type honeycomb heat exchangers, highly efficient, but problematic in cleaning and repair/replacement. On the other hand, simple tubular coils made of cold-drawn seamless pipe are hard to argue with the classics.

5. The presence of insulation. The need for a mineral-filled casing is determined by the installation site. If it doesn’t make sense to waste heat outside, then for a garage or workshop, an uninsulated boiler can be a good heating method.

There are also differences in the type of fuel, the horizontal and vertical arrangement of the shaft, as well as the material of the furnace. Chambers and coils made of cold-rolled low-carbon steel are simple and unpretentious, but prone to scale formation. Cast iron coils and water-filled jackets are the most durable and dross-free, but require special piping due to their high sensitivity to thermal shock.

Equipment power

Ultimately, for the boiler, it is not so much the details of its internal structure that are important, but the main performance indicators that have been achieved using a number of engineering innovations. The most important and defining parameter of the boiler is its nominal instantaneous power. The heat capacity of different types of fuel is different, as is the case with different types of firewood, the manufacturer cannot accurately predict it and calculate the rated power in a particular operating mode.

Power is determined by two indicators. By the volume of the furnace, one can judge the mass of the bookmark. On average, it is believed that for every kilowatt of wood-burning boiler power, there are 2.5-3 liters of combustion chamber volume. Having obtained the instantaneous value of the power released during combustion, it is possible to predict which part of it can be absorbed by the heat exchanger under different temperature operating conditions. Usually, absorption is deliberately made higher than the calculated heat release under combustion conditions close to optimal, but this approach is fraught with trouble.

The fact is that all wood-burning boilers suffer from a common disease - the formation of tar due to the high humidity of the burned wood. Condensation occurs only at a sufficiently high temperature difference. Thus, the formation of growths on the economizer or secondary heat exchanger may stop when the coolant is heated to 40-45 ºС. The bottom line here is that if you load the boiler halfway, its power will not be enough for the normal heating of the walls and heat exchangers, because of which the equipment will simply “leak”.

Chimney device

The main blow from the condensation of water vapor from firewood falls on the chimney system. The length of the pipe is large, the temperature difference (especially on the street) is very high. There are two approaches to solving this problem.

The first is the installation of revision outlets for draining condensed moisture. Such outlets should be placed at the lowest point of each rotary segment, starting from the last vertical section and ending with the boiler connection point. The disadvantage is that the pipes for draining water periodically need to be cleaned and cannot have a significant length with a small diameter.

With brick chimneys or with asbestos-cement pipes in the lining, such problems do not arise. The difficulties of constructing such chimneys are obvious, but they can be circumvented with the use of more expensive materials. We are talking about insulated stainless steel sandwich pipes with mineral filler. For a chimney device today, this is the best option. We summarize: condensate does not form only in insulated chimneys.

System inertia

Another disadvantage of a solid fuel boiler is hidden in the cyclical nature of its operation and the inability to replenish fuel reserves on its own. Because of this, either a high heat capacity of the house structure itself is required, or deaf insulation close to a passive house, or a way to store a supply of heat for the cooling period of the system.

Since the volume of the heat exchanger itself in the boiler is small, the displacement of the system can be increased mainly by increasing the diameter of the pipes. Another alternative of this kind can be called the installation of a heat accumulator. With a competent approach, it is possible to realize the accumulation of heat only after the heating of the main system, which will help speed up the warming up of the house and solve the problem with condensate.

Underfloor heating systems have their own high inertia, which grows with the thickness of the storage screed. In the presence of a thermal cutoff under the floor, this can be a truly long-term source of heat. With a sufficiently thick layer, even the use of water at a higher temperature will not cause discomfort and thermal zebra, but along with the inertia of the system, the time it takes to reach the regime increases. On the other hand, connecting a warm floor to a wood-burning boiler requires a rather complicated piping, which excludes overheating of both the boiler and the pipes in the floor.

Automation and piping of wood boilers

As already mentioned, the power of the boiler can be regulated only by changing the amount of oxygen supplied. This system works most efficiently and accurately in pyrolysis-type mine boilers on wood or briquettes.

The main automation complex includes an electronic control unit, a fan, an electrically driven draft regulator and a thermocouple tightly wound to the supply pipe. All these components are sold both individually and in kits for a specific model of the boiler. On average, all automation costs about 4-5 thousand rubles. Separately, we mention the importance of having protection against falling dampers and sealing grooves on loading and inspection hatches, a chimney, and a draft stabilization system.

For solid fuel boilers, a number of other types of protective devices are provided, installed in the hydraulic piping. Of course, this is a circulation pump and protection of the furnace from overheating - a safety group for relieving excess pressure. Please note that the outlet of the relief valve must be turned towards the wall or provided with a hose so as not to injure people present when actuated. Safety requirements may provide for the installation of a chimney pressure relief valve to stabilize draft and combustion; it is mounted immediately at the outlet of the boiler or directly in front of the final vertical section.

Connection diagram of a solid fuel boiler with a heat accumulator: 1 - chimney; 2 - thermostat; 3 - security group; 4 - air separator; 5 - circulation pump; 6 - thermal accumulator; 7 - three-way mixer; 8 - weather-dependent automation; 9 - heating radiator; 10 - circulation pump; 11 - check valve; 12 - expansion tank; 13 - protection against dry running; 14 - make-up valve; 15 — overhead temperature sensor; 16 - solid fuel boiler

For cast iron boilers, it is practiced to install a two-way valve that mixes water from the hot outlet to prevent cold water from entering the heated furnace. When installing a heat accumulator, a three-way electric valve is added, which starts the supply of heat to the tank only after the main composition has warmed up. The control is carried out according to the return temperature, the additional circuit is switched on 7-10 ºС before the cut-off temperature is reached. In this aspect, control units with a PID controller are most preferred.

Installation, connection

The boiler is installed on a concrete pedestal, the height of which is determined by the equilibrium of the hydraulic system. Ideally, the coolant in the boiler should be under the highest pressure compared to the rest of the pipeline. The position of the boiler is also determined by the direction and connection point of the chimney. Its connection can be either vertical (top) or horizontal (rear or side).

It is recommended to use only steel or copper pipes in the boiler piping; for plastic, the risk of overheating is too high. A section of the supply pipeline 3-5 meters from the boiler is also traditionally made of metal. Connections can be welded, in the absence of the necessary equipment - threaded on tow and anaerobic sealant.

The boiler must be adjusted taking into account the low heating rate and high inertia. The operating temperature of the coolant is maintained, as a rule, within 50-65 ºС. In this case, the temperature of the inverse hysteresis should be slightly higher than the maximum at which the boost completely stops. This is necessary so that ignition begins long before the water in the system cools down more than it should.

The main disadvantage of solid fuel heating boilers is the short operating time from one tab. The fuel in the furnace burns out within 2-3 hours. Boilers for long-burning wood have a special design that increased the battery life to several days.

The principle of operation of a wood-fired heating boiler, long burning

Long-burning wood-burning boiler with a water circuit, uses the ability of wood to oxidize, under the influence of high temperature and limited oxygen content. The wood is charred due to the large accumulation of smoke, which restricts the access of oxygen. A large amount of CO is released.

The device and principle of operation of a wood-burning boiler for long-term operation from one load is aimed at recreating such conditions in a limited space of the combustion chamber. Firewood does not burn in the full sense of the word, but smolders. The operating time increases, and the lack of heat is compensated by the afterburning of the emitted gases.

The design of long-burning boilers includes the following components:

Most long-burning boilers are equipped with an enlarged loading chamber. The internal device allows for autonomous operation for 8-12 hours. Some manufacturers offer boilers that can work from one gas station for several days.

How to choose a slow burning wood burning boiler

Heating boilers for long burning on wood are offered by several domestic and foreign manufacturers. The design of the equipment, as well as the thermal characteristics, differ significantly. When choosing a heat generator, pay attention to the following parameters:

1. Performance.
2. Design features.
3. Manufacturer country.

According to the three parameters listed above, they select a suitable boiler model for domestic needs.

Power calculation

A properly selected wood-burning long-burning heating boiler can easily cope with heating a living area up to 400 - 500 m². When choosing, take into account the performance of the heat generator. The power calculation is performed as follows:

1. Calculate the total area of ​​the house.
2. Calculate the required boiler power using the formula 1 kW = 10 m².
3. If there is a DHW circuit in the design, 15-20% of the margin is added to the result.

The above calculations are suitable for buildings with an average degree of thermal insulation, located in the middle latitude of Russia and having a ceiling height of no more than 2.7 m. For rooms with a complex configuration, a large number of window and door openings, calculations are carried out using online.

Design features

Types of long-burning boilers are usually classified into several groups, according to the following criteria:

Separately, it is worth highlighting boilers with a built-in storage boiler. Models of this type have one heating circuit, but are designed to heat the coolant and hot water.

Top Producers

Choosing the best wood-burning boiler for heating your home can be quite difficult, especially when you consider that products are manufactured in Russia, Austria, Germany, the Baltic states, the Czech Republic and Poland, and it is represented by at least a dozen different manufacturers. The cost of equipment, its thermal performance and reliability depend on the country of the manufacturer.

Thanks to consumer feedback, the following rating of long-burning wood-burning boilers was compiled:

• German boilers - equipment is offered by several companies, among which models and stand out favorably. The products are fully automated and are characterized by economical fuel consumption.
• Austrian boilers - produced models, are almost identical in quality to German units. A distinctive feature of Austrian boilers is the maximum automation and the presence of a multi-level security system. Products are offered by concerns, Wirbel, etc.
• Czech boilers - brands and ATMOS are considered the most popular. Universal stations operating both on wood and on other types of fuel remain in demand. Judging by the number of sales, boilers with cast-iron heat exchangers are in special demand among domestic consumers.
• Baltic boilers - the Russian consumer was able to evaluate the quality and thermal efficiency of the Latvian ones, the main advantage of which is a long operating time from one fuel tab. In offline mode, the boiler is able to work for more than 2 days. The design of the unit is so simple that local "craftsmen" offer device diagrams for self-assembly.
• Russian boilers - the first models of long-burning boilers, were not entirely successful, had many design flaws. In modern models, errors have been corrected, which has increased the popularity of heating technology. At the moment, the products are offered by Teplodar, Trayan and others. The low price of long-burning wood-burning heating boilers, unpretentiousness in terms of fuel quality - all this explains the high popularity of domestic products.
• Polish boilers - products of manufacturers are presented on the market:, Defro, Wichlacz. Boilers are practically analogues of German and Austrian companies, but at a more affordable cost. The popularity of the models is somewhat limited by the difficulties with the supply of components and the recently increased price of the units.

Features of the operation of wood boilers with long burning

The burning time of one bookmark of firewood is from 8 to 24 hours. The battery life depends on several factors:

1. Boiler type.
2. Fuel quality.
3. Proper operation.

Learning how to heat a boiler correctly is much easier than it might seem at first glance. During kindling and further operation, adhere to the requirements specified by the manufacturer in the technical documentation. After a few fires, the process becomes habitual.

How to achieve long burning wood

The consumption of firewood, subject to the use of the long burning mode, is 30-40% less than in conventional boilers. The efficiency reaches 92%. Not all consumers manage to get the boiler to work in the long burning mode the first time. Some complain about the copious release of resin during the burning of wood.

You can achieve long-term burning of firewood by carefully following the manufacturer's recommendations:

• Firewood is kindled with a fully open damper.
• In the mode of long burning, the boiler is transferred only after reaching a temperature of 600 ° C.
• The humidity of firewood should not exceed 20%. Heating with coniferous wood is not recommended.

Violations of the rules of operation leads to the fact that tar is formed from firewood in the boiler. Most often, the following conditions are not met:

• The minimum outlet temperature of the coolant must not fall below 65°C.
• It is correct to heat the boiler with hard wood: aspen, beech, acacia, oak, etc.
• The high humidity of firewood leads to an abundant release of resin.

Proper operation of long-burning boilers extends the life of the equipment and increases heat transfer.

How to properly load firewood

Stacking firewood in the boiler is carried out in accordance with the following rules:

• The logs are split into large pieces.
• Stacking firewood in the firebox is carried out as tightly as possible. It is important to avoid voids between logs.
• The length of the logs should be less than the size of the loading chamber, at least 5 cm.

Ignition is carried out exclusively with dry splinters. It is forbidden to use gasoline or kerosene to kindle firewood. From time to time, it is recommended to use special chemical briquettes that remove tar deposits on the walls.

How much firewood do you need for the winter season

The device of a long-burning boiler allows you to save on fuel, approximately 15-30%, depending on the model chosen. The approximate consumption of firewood is calculated as follows:

• It is generally accepted that for heating every 100 m², 3 Gcal / month will be required.
• When burning a kilogram of firewood, 3200 kcal is released.
• To get 1 Gcal, long-burning boilers burn 312 kg of firewood.
• To obtain 3 Gcal, approximately a ton of wood is required.

During the heating season, 7-8 tons of firewood are needed to heat a house of 100 m².

Rules and regulations for the installation of a long-burning wood-burning boiler

The installation of a long-burning boiler is carried out in compliance with the standards applicable to all wood-fired boilers. During installation work, the existing requirements of PPB and SNiP are taken into account:


In the room used for the boiler room, it is necessary to have supply and exhaust ventilation and natural lighting. If necessary, it is allowed to place the boiler in the basement.
