Heating of private housing can be organized in several ways. But the hosts country houses often prefer traditional wood heating. Logs in many Russian regions are the cheapest and most affordable fuel. However, the classic oven is no longer in great demand today due to low efficiency. A modern wood-fired long-burning boiler is more productive and requires less attention. It is he who is best chosen for the installation of the heating system of his cottage.

Description and principle of operation of long-burning boilers

Classic wood boilers, fireplaces and stoves require constant supervision. They need to throw new logs every few hours. Plus, as a result of the work of these heating appliances a considerable amount of ash and slag is produced, which must be regularly removed from the blower and taken out of the house.

Appearance

The functioning of long-burning boilers is based on limiting the flow of air into the furnace. As a result, wood does not burn quickly in them, as in an ordinary stove, but slowly smolders. The time of complete burning out of one bookmark of firewood increases several times. Plus, most of these boilers also have a large combustion chamber for laying fuel. As a result, it is required to lay logs only once every 6–20 hours.

Principle of operation

In fact, a long-burning wood-burning boiler does not burn firewood inside itself, but the gases formed during the smoldering of wood. At the same time, their combustion temperature, and hence the heat transfer for the heating system of a heated house, is much higher than that of ordinary logs. Plus, the tree as a result of such thermal decomposition practically does not form ash. Wood fuel is almost completely transformed into water vapor and carbon dioxide.

Types of wood-fired boilers

All long-burning boilers on wood are divided into two main types:

Top burning.

Pyrolysis.

In heating boilers of the first type, the direction of the flame and the outlet of gases are oriented from top to bottom. Structurally, this is a high firebox with a heat exchanger in the middle. When loaded into it, a large amount of firewood is laid, which are then set on fire from above.

And then, as a result of slow burning, the logs gradually sink to the bottom in the form of a small hill of ash. Air draft in such a boiler is usually natural. But there are also models with forced air pumping fans into the furnace.

Heating wood boilers of the second type are divided inside into two adjacent combustion chambers. In the initial, pyrolysis gas is formed from smoldering wood, and in the secondary, it is burned to produce heat. The coolant for home heating batteries is heated here just in the second furnace. The efficiency of installations in both cases reaches 90–100%.

Different kinds solid fuel

In addition to firewood, many models of the boilers in question are also designed to burn peat, wood pellets and even coal. However, it is impossible to put in them, for example, roofing material, rags in gasoline or other material for quick ignition. Wood should slowly smolder, not burn.

Multi-fuel wood-burning heating boilers allow you to use different types fuel as needed. But they cost more. Long-burning furnaces are generally expensive equipment. This is their main drawback.

Pros and cons of wood burning boilers

In terms of efficiency, modern wood-fired boilers are in no way inferior to gas and electric counterparts. The efficiency in all cases is approximately the same. However, in order to bring main gas to the house, you will have to go through lengthy agreements with obtaining specifications for connection. Plus, you will have to conclude a special service contract. gas technology for heating.

With electrical networks, it is still more difficult. If they are not designed to supply the required kilowatts to the boiler, then when laying additional wires and all related equipment, it will not take long to go broke. With wood fuel, everything is much simpler - you don’t need to coordinate anything, I purchased a heating unit and installed it myself in my home.

Long-burning boilers have a lot of advantages, among which stand out:

High degree of combustion of firewood;

Minimum harmful emissions into the atmosphere (almost everything burns in the furnace);

The presence of automation with the ability to fully control the temperature of the coolant and in the combustion chamber;

Long service life of the boiler on one tab (up to 20 hours);

High heat dissipation and efficiency;

Versatility (this technique is suitable for heating cottages, baths, garages, etc.);

Cheapness of fuel;

Unpretentiousness of service.

If the wood-burning boiler in question is operated in accordance with all the rules, then its service life will exceed two to three decades. Rather, the corrugated roof will rust from the rain than the firebox of such a unit will burn out. It is only necessary not to skimp on automation, the task of which is to prevent overheating of the equipment.

Among the disadvantages of these wood-burning boilers, it should be noted:

The high price of equipment;

The need to equip a separate furnace and woodshed;

Demanding on firewood (they must be dry).

Any heating boiler is far from ceramic blocks in the walls of a cottage that do not require any maintenance. Despite the presence of automation, equipment for heating the coolant requires attention. It needs to be monitored and controlled. Plus, every wood-fired boiler must be regularly cleaned from ash and soot accumulating inside. In this, it is much inferior to competitors on gas and electricity.

Features of the operation of a wood-burning boiler

If a wood-burning boiler has a fan for forced air supply, then it is volatile. It needs constant electrical power. If there are power outages in the village, then it is better to choose a simpler, albeit slightly less productive model. Or you have to take care of the availability small generator on solarium.

The heat exchanger of a heating wood-burning boiler is made of steel or cast iron. Steel variant lighter, but more susceptible to corrosion and less durable. It is better to give preference to a cast-iron counterpart. It will definitely last longer. He is only afraid of sudden changes in temperature, from which the heat exchanger made of cast iron can crack.

By itself, a long-burning solid fuel boiler can weigh up to 400–500 kilograms. Plus, the weight of firewood and water in the heat exchanger is added to this mass. For the installation of such a furnace, a specially equipped base is required. It is impossible to put such a heating boiler on an ordinary wooden floor.

In some cases, you will have to fill in a special foundation for the heater. Moreover, it is simply unacceptable to use bricks or foam concrete blocks for the construction of this foundation. Only concrete is suitable here. Otherwise, the technique in question is a good option for heating the coolant. Such equipment is suitable for heating both cottages and cottages, garages and outbuildings.

Heating systems and equipment are quite expensive. Not every family can afford to purchase a new boiler for installation in the country. You will have to spend a significant amount on its purchase and subsequent installation. However, if you wish, you can always make a wood-fired boiler with your own hands, capable of heating the living area.

In my own way design homemade wood-burning boilers can be different. Heating efficiency and ease of operation depend on their device. Having decided to do everything with your own hands, you should first pay attention to the simplest design. Pyrolysis wood boilers require certain knowledge and skills. Although their efficiency is much higher.

ordinary boiler

First, let's look at how to make a simple wood-burning boiler with your own hands. The model consists of two cylinders placed inside each other. The first is used as a firebox. With a horizontal arrangement, it can be lined with refractory bricks from the inside.

The second acts as a convection carrier or is used to heat the coolant. Firewood is loaded directly into the firebox.

improvised materials

To reduce the amount of welding work, you can use a thick-walled pipe or barrel. It is also possible to use other improvised materials.

A rectangular firebox welded from a thick sheet can be easily placed inside a cylindrical container.

Design features

The wood-fired boiler is provided with a blower for inflow fresh air and a chimney for exhaust gases. The blower is located at the bottom of the pipe and allows the bottom row of firewood to smolder, generating additional heat. Firewood is loaded into home-made boilers through the top. For this, a special hatch is being prepared.

In order for each pile of firewood to burn as long as possible, a special load is often provided, made in the form of a disk with blades and a hole having a diameter of 20 mm. When the load is pressed, the burning fuel is compressed. At the same time, the volume of incoming air is significantly reduced, since it can only pass through the existing opening.

Connection method

Such a boiler can be connected to the heating system in two ways:

• ramming pipes with water directly into the barrel. Circulating between the pipes, it will heat up, so that when it enters the heating system, it heats the radiators;
• cutting the chimney into the tank with the coolant. Exhaust hot gases will enter the tank, gradually heating the coolant.

pyrolysis boiler

The principle of operation of solid fuel pyrolysis boilers operating on wood is based on the destruction of wood under the action of high temperature at low oxygen levels. They are used for long-term heating of premises for various purposes.

Such a boiler consists of two chambers. The first is used to load fuel. The second one receives exhaust gases and secondary air for long-term combustion. Making such a unit with your own hands is more difficult than a regular one, but it is possible.

Main elements of the device

The wood burning boiler is made from metal barrel. Preferably with a capacity of 200 liters. The lid of the barrel is cut off and a side is welded to it. A round piston is made from a massive billet or any other weighting agent. Its diameter should be slightly smaller than the inner diameter of the barrel.

A hole is cut in the cover for installing an air pipe with a diameter of 100 mm. In height, the pipe must be at least 20 cm higher than the barrel. A chimney pipe is welded into the barrel from the side. It also uses rolled products with a diameter of 100 mm.

The air pipe is welded to the piston. At the top end of the pipe, a damper is provided that regulates the amount of incoming air. Ribs are welded to the bottom of the piston, used to compact the fuel mass.

During the operation of the boiler, firewood is loaded directly into the furnace and ignited. A piston cap is installed on top. As the fuel burns, the piston will move down, building up pressure in the lower chamber. Due to this and the minimum amount of oxygen, the firewood will slowly smolder.

The gas released during pyrolysis will enter the upper chamber, the temperature in which can reach 900C. Through the chimney, the residues of combustion products are removed into the atmosphere.

Such home-made boilers, made according to all the rules, are able to work on one tab for more than a day due to long burning.

We prepare material and tools

When starting to make a wood-fired boiler with your own hands and trying to complete everything in the shortest possible time, you should take care of the availability of:

• schemes of the future boiler;
• steel pipes of various lengths, diameters (400, 500, 100 and 150 mm);
• steel sheet at least 4 mm thick;
• rolled products for the manufacture of legs;
• two hundred liter barrels;
• heat-resistant mixture used when laying stoves and fireplaces;
• welding machine;
• electrodes of a suitable brand and size. As a rule, electrodes with a diameter of 3–4 mm are used for welding;
• Bulgarians.

Assembly process

The process of creating a boiler includes several stages. In the manufacture of each element, it is worth considering special conditions operation of the manufactured product.

We cut off a segment from a thick-walled pipe with a diameter of 100 mm, the length of which will be equal to the height of the furnace. Weld a bolt to the bottom. From the steel sheet we cut out a circle of the same diameter as the pipe or larger. We drill a hole in the circle, sufficient for the passage of a bolt welded to the pipe. We connect the circle and the air pipe by screwing the nut onto the bolt.

As a result, we will get an air supply pipe, the lower part of which can be closed with a freely moving metal circle. During operation, this will allow you to regulate the intensity of burning firewood and, consequently, the temperature in the room.

Using a grinder and a metal disk, we make vertical cuts in the pipe with a thickness of approximately 10 mm. Through them, air will flow into the combustion chamber.

Housing (furnace)

The case requires a cylinder with a sealed bottom with a diameter of 400 mm and a length of 1000 mm. The dimensions may be different, depending on the available free space, but sufficient for laying firewood. You can use a ready-made barrel or weld the bottom to a steel thick-walled cylinder.

Sometimes heating boilers are made from gas cylinders for more long term services.

Chimney

In the upper part of the body we form a hole for the removal of gases. Its diameter must be at least 100 mm. We weld a pipe to the hole through which exhaust gases will be removed.

The length of the pipe is selected depending on the design considerations.

We connect the case and the air supply device

In the bottom of the case, we cut a hole with a diameter equal to the diameter of the air supply pipe. We insert the pipe into the body so that the blower goes beyond the bottom.

The air supply pipe should end a few centimeters before the start of the chimney.

From a metal sheet with a thickness of 10 mm, we cut out a circle, the size of which is slightly smaller than the diameter of the body. We weld to it a handle made of reinforcement or steel wire.

This will greatly simplify the subsequent operation of the boiler.

convection hood

We make a cylinder from sheet steel or cut off a piece of pipe, the diameter of which is several centimeters larger than the outer diameter of the furnace (body). You can use a pipe with a diameter of 500 mm. We connect together the convection casing and the firebox.

This can be done using metal jumpers welded to inner surface casing and the outer surface of the furnace, if the gap is large enough. With a smaller gap, you can weld the casing to the furnace around the entire perimeter.

From a steel sheet we cut out a circle of the same diameter as the firebox or a little more. We weld handles to it using electrodes, wire or other improvised means.

Considering that during the operation of the boiler, the handles can become very hot, it is worth providing special protection from a material with low thermal conductivity.

legs

To ensure long burning, we weld the legs to the bottom. Their height must be sufficient to raise the wood-burning boiler at least 25 cm above the floor. To do this, you can use a different rental (channel, corner).

Congratulations, you have made a wood-burning boiler with your own hands. You can start heating your home. To do this, it is enough to load firewood and set it on fire by opening the lid and the heat-dissipating disk.

Although science and technology have come a long way, it is undeniable that even today the use of appliances such as wood-burning boilers for home heating is common.

Most models of modern wood-burning boilers today combine these two elements: a traditional source of thermal energy - firewood, as well as a steam heating system that came into use relatively recently - 100-150 years ago.

For those who live in the city, it may seem strange such a pursuit of the traditions of antiquity in the form of wood-burning boilers. However, this cannot be said about villages and villages. After all, there is no passing gas pipeline here, electricity jumps, and it will be expensive to pay bills. It is in this case that wood-burning boilers for heating the house will become the only salvation for people in the cold season.

Wood boiler design for home

The design of devices such as wood-burning boilers for hot water heating is not new. It was in the likeness of a wood-burning boiler that was created a long time ago geyser, and later - a gas boiler. Only instead gas burner in such boilers, a flame from burning solid fuel is used.

It is worth noting that not only firewood familiar to everyone, but also coal, peat, and household waste can be used as fuel.

Above the combustion chamber is a radiator, which is usually made of heat resistant pipe, twisted spiral. The pipe is connected to closed circuit steam heating. You can also connect to a hot water system.

Wood boiler device

So, how does heating a house with a wood-fired boiler work? The water is coming into the boiler, passes through the heat exchanger, heats up and goes to the battery outlet. With the help of taps, you can regulate the water supply and pressure.

Of course, unlike gas, neither wood nor coal burns without a trace. And even if the boiler is the most modern and perfect, ash remains, which accumulates in the ash pan.

The ash pan is located under the stove and is separated by a heat-resistant grate. Sometimes the ashes should be poured out, as a lot of it can accumulate.

Firewood for heating

The firewood that a wood-fired boiler uses to heat a private house is also an important issue. When you plan to install a wood-burning boiler, you need to take care in advance that fire regulations and requirements are observed. In addition, it is worth taking care that there is always a good supply of firewood. Therefore, you need to decide on the place of their storage, which must be protected from moisture.

As a rule, firewood is prepared for the winter in advance, storing it in utility room or in the yard, which has a canopy. The amount you need for heating season are determined empirically. It depends on several aspects:

• Features of climatic conditions.
• The thickness of the walls and the material from which the house is built.
• area to be heated.
• Comfort and personal temperature preference.

In those places that are remote from the gas main, wood-burning heating boilers for summer cottages are used not only in domestic conditions.

You can find industrial facilities that are heated in this way. Of course, devices for industry will have large dimensions, and also be characterized by greater automation of the heating process.

How much fuel, what water temperature, what level of pressure will be monitored by sensors that are connected to the built-in processor. Often this same element controls the automated fuel supply. The indicators will show a signal about the degree of filling of the ash container.

Thus, automation of the heating process was able to reduce heat loss. Also, the efficiency of the boiler is increased, and the fuel consumption and the amount of waste are reduced.

A wood-fired heating boiler for a summer residence will be an excellent option if conditions do not allow resorting to the use of traditional heating systems. If we evaluate such heating as the main one, then heating a country house with a wood-burning boiler is more troublesome compared to gas. Yes, and in terms of costs - both financial and labor - it is clearly inferior to traditional heating. However, if you have no other choice, such a system will help to heat the house and create comfortable conditions in it.

When cold weather sets in, it is extremely important that your home be cozy, comfortable and warm. This must be taken care of in advance by organizing a high-quality heating system. The key issue in such a case is always the choice of the boiler.

The range of online and offline stores presents a huge number of options for the choice of the buyer: units operating on solid and liquid fuel materials, connected to the mains or gas lines, combined devices. From the point of view of specialists, one of the most rational decisions there will be a wood-burning boiler for heating a private house.

An indisputable plus of solid fuel models is efficiency. This equipment is more difficult to maintain and loses in some respects to other types of heating devices. But in case right choice it will be no less effective. What to consider when buying and which models to pay attention to? Next, we will talk about everything in detail.

There are many models of wood-burning heating units. Depending on the manufacturer and price, the equipment has different technical parameters, design specifics, features of work.

After analyzing the reviews of the owners of private houses, we identified the top ten best models and collected them in a separate rating. Places in it are distributed on the basis of user ratings and operational qualities shown in practice. We invite you to get to know each participant in more detail.

A feature of the model is a removable hob, which serves as an ordinary household stove for cooking.

This heating boiler runs on wood and coal. However, due to the insufficient depth of the firebox, only finely chopped wood will have to be used in it.

The unit is provided with good thermal insulation and efficient heat exchanger design. The operation of the device is automated by a mechanical traction control. To control the temperature, a thermometer is built into the panel, but there is no pressure gauge in the equipment.

In general, the device copes well with its tasks, but, judging by the user reviews, it is not very convenient to maintain.

Rules for choosing a heating boiler

Before proceeding with the selection of a specific model of a heating boiler, it is necessary to study the criteria that should be guided by. Understanding the features of operation and the main parameters of the equipment, you can choose a device that can satisfy all your needs.

First of all, consider the following nuances:

• boiler type and efficiency;
• camera design;
• the power of the device and the area of ​​​​the room;
• combustion time and supported fuels;
• heat exchanger material;
• additional functions and protection systems.

Boilers are single-circuit and double-circuit. The first option is connected to an autonomous heating system and is intended exclusively for heating. Some models work in conjunction with a boiler.

The second option replaces the water heater and boiler, providing not only heating, but also hot water supply.

The efficiency indicator of the boiler, expressed in the efficiency parameter, shows how productive the device is. The higher it is, the less fuel materials will be needed to heat the room.

One of the main indicators of the equipment is the output thermal power. This parameter must be selected based on the area that is supposed to be heated.

It is highly desirable that the model has the ability to adjust the power, allowing you to achieve the optimal comfortable temperature.

Boilers with open type chamber designs take oxygen from the room and remove combustion products through the chimney. They should be installed in places with good ventilation. Units with closed type cameras can be placed almost anywhere

The frequency of bookmarking depends on the time of fuel combustion in the boiler. Retains heat the longest pyrolysis boilers, devices of long burning. The best option there will be units that work not only on wood, but also on alternative types fuel.

Also, when choosing, it is important to pay attention Special attention to the heat exchanger:

Operational safety and equipment efficiency are enhanced by additional built-in mechanisms and functions. It is good if the selected model has overheating protection, devices for regulating traction, measuring current pressure and temperature indicators.

Conclusions and useful video on the topic

Boilers operating on wood and other types of solid fuels are an excellent alternative for non-gasified private houses. They are economical, autonomous, non-volatile.

Despite the characteristic disadvantages of such boilers, among available options on the market you can find a completely worthy model that fully compensates for them. The main thing is to choose a high-quality boiler with a reliable, practical design and power corresponding to the area of ​​a particular room.

Traditional heating stoves have been replaced by wood-fired boilers. domestic production. The main advantage of wood-fired boilers made in Russia is unpretentiousness to the quality of the fuel used and operating conditions, low cost (compared to European units).

Manufacturers of wood boilers in Russia

The domestic consumer has already been able to form a definite opinion about domestic and industrial solid fuel boilers on firewood, the Russian production. Like any other heating equipment, the products have their advantages and disadvantages.

Types of wood-burning heating boilers manufactured in Russia can be divided into several classes:

1. According to the principle of work.
2. The presence of a DHW circuit.
3. Destiny.
4. type of heat exchanger.

On the this moment, the consumer is offered traditional and gas generating models, with a built-in hot water supply circuit or the ability to connect an indirect heating boiler.

We offer domestic boilers for firewood of the following designs:

• Russian-made gas-fired wood-burning boilers. For a long time, the manufacture of this type of equipment, was the prerogative of exclusively European companies.
  At the moment, domestic-made wood-burning pyrolysis boilers of long burning are offered by several companies at once. The advantage of "our" equipment is the reduced consumption of firewood and more long work from one bookmark.
• Boilers with a conventional design - heat generators of this type, according to the principle of operation, resemble a conventional wood-burning stove. The difference is the complete set of the structure with a water circuit. It is allowed to connect to a conventional radiator heating network with or coolant.

In addition to the design features and the principle of operation used, when choosing our wood-fired boiler, they are guided by the manufacturer's company. Not every factory produces products of the same quality and reliability. When choosing a boiler, it will not be superfluous to study real customer reviews who have been using the equipment for some time.

Which domestic wood-fired boiler to choose

Russian-made wood-fired hot water heating boilers are offered by more than a dozen different manufacturers. Judging by customer reviews, the products of the following companies are especially popular:


Modern Russian-made wood-fired water heating boilers are in no way inferior to Western counterparts in terms of their characteristics. The design uses new technologies that ensure the autonomy of the heat generator and a high degree of safety. Automation controls the heating of the coolant.

Many models use a backup heat source, which is very convenient when heating with wood. When the fire in the furnace dies out, the electric heating element turns on and continues to heat the coolant, preventing the house from cooling down.

At Russian enterprises, steel boilers are mainly manufactured, but a series of equipment with cast-iron heat exchangers and high performance(factory KCHM). Models are intended for domestic use.

Wood boilers of high power, for industrial purposes, of all the above manufacturers, are manufactured only by KZKO LLC.

The cost of Russian wood boilers

The cost of domestic wood heating equipment, approximately 2-3 times less than European counterparts, which explains its demand among consumers. The price is affected by the equipment configuration, the type of heat exchanger and the brand of equipment.

For example, below is the cost of units, depending on the manufacturer, of approximately the same power and identical parameters. Productivity from 15-20 kW.

• PARTNER (Bonfire) - boilers of small power, 16 and 20 kW, will cost 21,960 and 24,990 thousand rubles. respectively.
• DON (Conord) - the price, for a heat generator similar to the previous one, varies between 24-28 thousand rubles, depending on the configuration.
• Stoker Aqua (Ermak) will cost only 20 thousand rubles, provided that it is equipped with an electric heating element.
• KCHM (Kirov Plant) - the highest cost of boilers among analogues of this class is due to the presence of a cast-iron heat exchanger. A 21 kW heat generator will cost about 44 thousand rubles, in the basic configuration.
• The geyser is one of the most reliable heating boilers on the domestic market. The cost of pyrolysis equipment varies between 44-48 thousand rubles.
• Zota - equipment, in terms of quality and automation of boilers, as close as possible to European units. The cost of a 20 kW boiler will be about 33 thousand rubles.

Price policy domestic manufacturers takes into account the fact that the produced units are somewhat inferior in quality to their foreign counterparts.
