The average rate of gasification in the regions of the Russian Federation is only 70%. Therefore, solid fuel boilers remain relevant in the market. The segment continues to develop, models with new features appear. In addition to classic solid fuel boilers of various capacities, manufacturers offer innovative pyrolysis and long-burning boilers. Experts are betting on the latter more and more often. But the classic ones, due to their low cost, remain in demand. Based on these two theses, I compiled a rating of the TOP 10 solid fuel boilers in 2022, which included popular models of various types. Hope this helps you make the right choice.

Technical parameters of solid fuel boilers

So, what should you pay attention to if you decide to choose the best solid fuel boiler:

• Type of fuel. Different models may consume one or more types of fuel. Firewood, coal, peat briquettes, sawdust, pellets, straw or recycled waste are suitable for use.
• Power. It must be calculated in such a way that it is enough to heat the entire area of the house and auxiliary premises.
• Combustion chamber volume. This is one of the main indicators affecting the performance of the unit, the frequency of fuel loads.
• Automation. The presence of such a mechanism allows you to free the owners from constant monitoring of the boiler.
• Safety. The main elements necessary in any boiler are an alarm and an auto-shutdown function in case of a malfunction.
• The need for access to electricity. Some models of heaters are simply not able to work without access to electricity. But most of the boilers can still carry out heating completely autonomously.
• Useful factor. this indicator is calculated as the ratio between the actual power of the device and the heat capacity of the fuel used. The higher the efficiency, the less fuel is required to generate one unit of heat.
• Operating time on one load. The inability to control the process makes the burning period of the fuel very short. You are unlikely to like a boiler that needs fuel every 4-5 hours. Modern models can work on one load for several days.
• Ease of maintenance. Even the most wonderful boiler needs to be cleaned of soot and ash, purged and loaded with a new portion of fuel. The simpler all these processes are arranged, the more satisfied the owner will be.
• Price. Boilers for heating a house are not the equipment that is worth saving on. In this case, you should not choose a heater, focusing only on a low price. The technical characteristics of cheap boilers are often far from ideal.

Only by comprehensively approaching the study of all the main parameters, we can choose for ourselves the best long-burning solid fuel boiler in 2022.

TOP-5 classic solid fuel boilers

Classical boilers use for heating the heat obtained as a result of combustion inside the furnace. Most often, coal is used as fuel, firewood, peat briquettes are used. However, coal is still more economically profitable. Such boilers consist of a loading chamber with a heat exchanger and an ash pan – the lower part of the furnace for collecting ash. The disadvantages of such boilers are that you need constant monitoring of the process: reloading fuel, cleaning the ash pan and heat exchanger, most often low efficiency, although for some models it reaches 90%.

Teplodar Kupper Practice 8

Compact boiler capable of heating a room / several adjacent rooms with a total area of ​​​​up to 80 m². It uses firewood, coal, peat briquettes as fuel. Reliable – the heat exchanger is made of steel, the boiler body is cast iron. It has a built-in heating element to maintain the temperature, however, you will have to think over the power supply and grounding scheme. Heater power – 6 kW. Equipped with a thermometer to control the temperature. You can set the automation to maintain the set temperature with minimal user intervention. The price is 13 thousand rubles.

Pros:

• price;
• compactness (420×565×595 mm);

• not enough power to heat a large house;
• case may become hot.

Budget proposal of a well-known manufacturer. Suitable for heating a garage, an extension, a small private house. Judging by user reviews, the heated area indicated by the manufacturer is somewhat overestimated. Optimally, in order to warm the air well even in severe frosts, you need to use the boiler in rooms of about 60 m².

Lemax Forward-12.5

Differs from Teplodar KupperPraktik 8 in vertical fuel loading. This is convenient: you can pour coal from a bucket. This design feature is associated with a significantly higher height of the device. This model does not have heating elements to maintain the temperature. The maximum thermal power is 13 kW. Heated area – up to 130 m². Fuel – coal, wood, coke. It is possible to install a non-volatile traction control. The price is 15 thousand rubles.

Suitable for homes up to 100 sq. m. As in the case of Teplodar KupperPraktik 8, the heating area declared by the manufacturer is overestimated, in severe frosts the boiler will not cope with it. Vertical loading of fuel is a controversial solution: it speeds up the process of its supply to the furnace, but has a side effect in the form of smoke and dust in the room.

ZOTA Box 8

Compact boiler, working on coal and wood. Designed for heating up to 64 m². It has a hob – you can heat food or heat water, very convenient in a small production. It is possible to connect heating elements to maintain the temperature and a draft regulator – they are not supplied in the kit. The price is 16500 rubles.

A smart solution for a small home or workshop. A nice bonus is the ability to warm up food. If the latter is not important for you, you can save money and purchase Teplodar KupperPraktik 8.

ZOTA Poplar M 14

A popular boiler in our country. The reason is a large heating area (up to 120 m²), undemanding to fuel quality, large loading chamber. It has a separate large chamber for loading firewood, a solid assembly and a good design. You can connect a heating element and a draft regulator, but they will have to be purchased separately.

A good boiler for heating a large house. It can be used as an auxiliary, in the presence of a gas or electric boiler. Taking into account the “lame” reliability, the weak point is the heat exchanger radiator and the high price, so I can’t unequivocally recommend this boiler.

TOP-2 pyrolysis solid fuel boilers

Pyrolysis boilers as a heat source operate on gas obtained by dry distillation, heated to temperatures of 600–800 degrees without air. Dry wood is considered the best fuel for such boilers – it gives the maximum amount of pyrolysis gas. Some models use coal as fuel. The design of such boilers is simple. Two chambers – a loading furnace and a gas combustion furnace. Advantages – requires less human intervention, it is possible to load fuel and clean the furnace less often, high efficiency (up to 90%) Disadvantages – dimensions and high price.

ZOTA Master 18

Boiler with a high level of efficiency (73%) and a hob. You can heat with coal or wood. It is convenient to monitor the readings of the system using the built-in pressure gauge and thermometer. The maximum heat carrier temperature is 95 °C. The maximum pressure in the heating circuit is 3 bar. Heated area – up to 144 m². The price is 26300 rubles.

• smokes, overheats, clogs the chimney with tar due to improper installation and operation.

If you decide to buy such a boiler, it is better to call professionals to install it, from whom you can take a guarantee for the elimination of installation defects if they are detected. Otherwise, you risk getting a lot of problems due to the design features of the device. For beginners, I recommend an ordinary solid fuel boiler, for example, ZOTA Topol M 14 or more powerful models (for example, Topol M) for heating a large area.

TOP-3 solid fuel boilers for long burning

Long-burning boilers differ from conventional ones in a special air supply. Fuel burns out gradually, starting from the upper layers. Advantages – a large volume of the furnace, almost complete combustion of fuel, its economy, a minimum of ash and emissions into the atmosphere. Cons – relatively low efficiency.

ZOTA Poplar-16VK

New for 2019. Attractive is the variability of fuel loading: coal can be loaded through the top door of the furnace, located at an angle, for convenient loading from a bucket or bag, and firewood can be thrown through the sling door. The model has an increased heat exchange area and a large firebox. The burning cycle for 1 load is up to 10 hours. Any type and quality of fuel is suitable. Technically, the model received water-filled grates and a modified configuration of the heat exchanger: its tubes are made in the shape of a triangle, which reduces soot deposition on them and simplifies cleaning. Heated area – up to 120 m². Additionally, you can install heating elements, a draft regulator. The price is 30500 rubles.

Pros:

• quality materials and assembly;
• fuel economy;

Teplodar Kupper Expert-15

Universal top burning boiler with a large furnace, convenient vertical loading of shaft-type coal and additional sources of air supply. This ensures long-term burning – up to 24 hours from one load. For ease of loading and minimizing the risk of fuel spillage, a second stainless steel door is provided: everything that spills will remain in it, you just have to turn it over, sending the remaining fuel to the furnace. During operation, it also serves as protection against burning out of the main door. The same stainless steel plate protects the cleaning door. Supplied with a gate valve with 5 fixed positions. The heat exchanger is cleaned through the top door – very convenient. To maintain the temperature, a 6 kW heating element is already built into the boiler, but the draft regulator will have to be purchased separately. The price is 35 thousand rubles.

Pros:

• high quality materials and assembly;
• the ability to use any type of fuel;
• you can connect the system from any side;
• complete set (thermomanometer gate, heating element, accessories for cleaning);
• long burning;
• large heated area – up to 115 m²;
• additional air supply;
• convenience of loading fuel, cleaning the boiler;
• the possibility of installing a draft regulator, pellet or gas burner.

Minuses:

• price;
• dimensions.

High-tech boiler, easy to operate, a good option for giving. If you can find fault with something, then these are the dimensions – after all, a separate room is needed for it. The price for this level of workmanship is justified, although some consider it high.

Stropuva Mini S8

The Lithuanian brand Stropuva is the progenitor of long-burning boilers. A bright representative of the company is the Stropuva Mini S8 model. Bright – both from the standpoint of technical equipment and from the standpoint of appearance: the yellow cylindrical body attracts attention at first sight. Boiler dimensions – 1350×557×557 mm, definitely require a separate room for installation. At the same time, the heated area is only 80 m². Duration of burning from 1 load – up to 24 hours. This is achieved by adjusting the height of the air distributor and thanks to the built-in draft regulator. The price is 52900 rubles.

Pros:

• build quality and materials;
• design;
• long burning;
• the possibility of using any fuel;
• low fuel consumption;
• retains heat for a long time;
• thoughtful design that allows you to adjust the air supply and draft.

Minuses:

• weight – 164 kg;
• price;
• low power;
• it is impossible to build in a heating element: probably, with such a duration of burning, it is not needed;
• the window for loading briquettes, coal and firewood is located inconveniently (too low);
• there are traces of use on the lining, which are very difficult to remove.

Great boiler for a small home. The price will be justified during operation due to fuel economy. As an alternative, I can offer Teplodar Kupper Expert-15. I consider it more profitable (costs almost 20 thousand rubles cheaper) acquisition, heats an area 2 times larger, has its own design advantages that ensure a long service life, long burning and fuel economy.
