When choosing solid fuel boilers, you should not focus on price; first of all, decide on the preferred type of fuel, the area of ​​the house, pay attention to technical specifications devices. Unreasonable savings in this matter can lead to significant waste in the future.

Models of solid fuel heating equipment are an excellent alternative to their counterparts running on liquid or liquefied fuel. Recently, boilers designed for long-term combustion have been in great demand. They are able to work autonomously for several tens of hours. When choosing the best modifications to the device, you should be guided by consumer reviews. The rating of equipment included in the top 5 most popular models of 2016-2017 will greatly simplify the task.

Running on solid fuel, it is a good alternative to its counterparts running on natural gas, diesel fuel or electricity. Such equipment is especially in demand in areas without gas supply or remote from regional centers, as well as where there are constant interruptions in the operation of power lines. Solid fuels are produced for both industrial and domestic use.

Types of solid fuel boilers

On the heating equipment market, boilers are presented in a wide range from different manufacturers. In turn, companies have several lines of their equipment, of which there are many models. This circumstance significantly complicates the choice of the optimal option for specific operating conditions. Therefore, solid fuels can be divided into several categories:

Advice. Boilers with an efficiency of 83–90% have an optimal ratio of fuel chamber volume/burning duration. At the same time, they operate at the maximum power declared by the manufacturer.

Rating of boilers by type of fuel

Solid fuel boilers are highly versatile. Models designed to operate on wood or coal can use pellets or briquettes as fuel. Based on the technical characteristics of the equipment and reviews of specialists and ordinary consumers, we can make a rating of the best models.

Stropuva S 40

A long-burning boiler operating on wood, coal or wood briquettes takes first place in this rating. The equipment of the Lithuanian-Russian company STROPUVA has the highest efficiency of 95%. An impressive firebox volume of 320 dm. cube holds 50 kg of fuel. Depending on the operating mode, one boot of the device ensures uninterrupted operation from 31 to 130 hours. The maximum heated area of ​​the room is 400 sq. m. It is also designed to run on pellets or coke. Its design provides for one heating circuit, which determines its use only for the heating system. The device power is 40 kW, liquid temperature 85 °C, operating pressure 2 bar.

Zota Pellet 25

The boiler is designed to operate on wood pellets and takes second place in the rating. Products from a domestic manufacturer are equipped with an LCD display, which displays all the necessary information: current status, operating mode settings, errors, etc. The automation system is capable of monitoring and managing both the equipment itself and secondary devices. For example, it is capable of controlling up to five circulation pumps of the heating system and underfloor heating. The pellet boiler has a high efficiency of 90%; its power of 25 kW can effectively heat a house up to 250 sq. m. One full load ensures uninterrupted operation of the equipment for up to 50 hours.

Attention! Boilers operating on briquetted fuel and wood pellets are equipped with an automatic firebox loading system. This function significantly increases the combustion duration and autonomous operation of the equipment.

Buderus Logano G221-20

The third place is occupied by a German boiler, which has high reliability and stability in its operation. It does not have automatic fuel loading, but maximum length logs should not exceed 68 cm. High efficiency of 90% and power from 10 to 20 kW compensate for minor shortcomings. The heat exchanger made of cast iron has high coefficient heat transfer, which ensures rapid heating of the media to the required temperature. The device can operate on wood, coal and coke.

Protherm Beaver 50 DLO

A cast iron boiler from a Slovak manufacturer ranks fourth. He has quite high technical characteristics: Efficiency – 90%, power – from 35 to 40 kW, depending on the type of fuel, liquid temperature – 90 °C, operating pressure – 2 bar (maximum – 3 bar), heated area – up to 260 sq. m. The low level of heat loss is due to the use of inorganic wool as insulating material between the firebox and the equipment body.

Teplodar Cooper OK30

Products of domestic manufacturers take fifth place. This is due to the relatively low efficiency of 84%. Due to its high power of 39 kW, it is capable of heating liquid to operating temperature in 20 minutes. It is capable of efficiently heating a house up to 300 square meters. The boiler is designed to operate on wood, pellets, coal, and if necessary, natural gas or electricity can be used as fuel. All its advantages raise the equipment to a fairly high place.

Advice. A boiler equipped with a cast iron heat exchanger has a high degree of heat transfer and service life, which increases its efficiency and reliability several times.

Rating of boilers by price

The cost of heating equipment plays a key role when choosing the required model of a long-burning solid fuel boiler. In every price segment present best models, which are able to meet almost all consumer requirements:

Budget class

The low cost of heating equipment does not mean low performance, reliability and lack of stable operation. This class contains models that are perfect for cottages and small private houses:

Standard class

The leader in this segment is the Lamborghini WBL 7 boiler. It has a high efficiency of 90%, heat and soundproofing characteristics. A power of 30 kW allows you to heat an area of ​​up to 270 sq. m. Autonomy on one full load is 12 hours, maximum water temperature is 90 °C.

The second place is occupied by the Czech boiler Viadrus Hercules U22D-4. Due to its efficiency of 80% and a power of 20 kW, it effectively heats a house of 180 - 200 sq. m.

How to choose a solid fuel boiler: video

Wood boilers for home heating are still popular, despite the variety of models of gas and electric boilers, and there is a simple explanation for this: firewood is the most affordable type of fuel for country houses, not connected to the main gas. The efficiency of modern wood-burning boilers is quite high, their efficiency reaches 85%, and not only wood, but also pellets, as well as wood waste, can be used as fuel.

Wood boilers used for heating country house, easy to connect and use - they are even easier to handle than a stove. They are safe if the installation and operation instructions are followed. The only serious disadvantage of wood boilers is low level automation of the process: loading fuel into the boiler must be done manually. A way out of the situation may be a boiler with a long-burning function or a combination boiler that runs on solid fuel and has an additional diesel or gas burner or electric heating element.

Despite huge selection models of wood-burning boilers, their design differs not so much. Any wood-burning boiler for heating a house must have a fuel combustion chamber, a water heat exchanger, a chimney and an ash pan. The simplest wood-burning boiler resembles a potbelly stove with a water jacket: when wood burns in the firebox, the water heats up and enters the heating system. The efficiency of such a boiler is low, and the consumption of firewood is significant; due to incomplete combustion of fuel, part of the money literally goes down the drain. The design of modern boilers with a long-burning function is, of course, more complicated; the structure of such a boiler and its main elements are shown in the figure.

Firewood is loaded into the boiler through the top loading door in large quantities at once. The initial combustion of the fuel occurs in the gasification chamber. The supply of air, and with it the oxygen necessary for combustion, into this chamber is limited - this is how the intensity of combustion is regulated. In this mode, the wood does not burn, but smolders, producing more heat, and the water in the heat exchanger is heated. But the combustion process does not end there: during smoldering, smoke containing flammable gases is formed. These gases enter the second chamber - the combustion chamber, which also serves as an ash pit. The air supply to this chamber is no longer limited, and with a sufficient amount of oxygen, afterburning of gases occurs. The combustion temperature of the gas-air mixture is very high, and the heating efficiency of the water heat exchanger in this chamber is also very high. As a result, the smoke is cleared of ash and harmful combustible gases, which makes the new generation of wood-burning boilers very environmentally friendly.

Pyrolysis is a long-term combustion process

Video - the operating principle of a long-burning wood-burning boiler

Smoke is removed through a chimney duct connected to the chimney and pipe. To supply cold water and remove hot water from the heat exchanger, the boiler is equipped with pipes. They are connected to the heating system according to the selected scheme. New generation boilers are equipped with automatic equipment that makes boiler maintenance as simple as possible:

• a temperature sensor that sends a signal to the primary air supply fan;
• a pressure sensor that signals when the normal value is exceeded;
• water pressure sensors in the system.

The efficiency of solid fuel boilers directly depends on the type and quality of fuel. If the boiler is designed to operate on wood, you must not load coal or peat briquettes into it! This will reduce the efficiency of the boiler and may damage it. It is also not recommended to use poorly dried firewood and coniferous wood to fire a wood-burning boiler - they burn with the formation of large quantity steam, tar and soot, and the boiler will have to be cleaned much more often.

Wood boilers - choice

When choosing a wood-burning boiler, you must begin by calculating the required power - this parameter is indicated in the boiler’s passport and is measured in kilowatts. One kilowatt of boiler power is enough to heat ten square meters well-insulated room. For example, in the middle zone, to heat a house with an area of ​​100 square meters, a boiler with a power of 10 kW is needed. For frosty days and poorly insulated rooms, a power reserve of 20-30% is required. When choosing, you should pay attention not only to the rated power, but also to the entire range in which the boiler can operate - in the fall and spring it is not advisable to heat the boiler at full power. If you plan to use the boiler also to produce hot water, then you will need an external boiler and an additional supply of boiler power based on the number of people permanently living in the house.

The boiler material – steel or cast iron – plays an important role. Steel boilers are lighter and have more simple design fireboxes that are easier to clean - just remove the ash from the ash pan. The smoke channel of steel boilers is longer, so heating of the coolant occurs more efficiently. Cast iron boilers have a shorter smoke channel, and a larger heat exchange area is achieved due to the ribbed surface in which combustion products settle; a cast iron boiler will have to be cleaned using brushes, scrapers and pokers. At the same time, the heat capacity of the boiler itself is higher for cast iron models.

A separate type is electric wood-burning boilers, which use electricity to further increase efficiency. Modern automation monitors the combustion process and influences it using valves that regulate the flow of incoming air into the firebox, so you can control the temperature in the firebox at a given level!

Wirbel steel wood burning boiler

An important indicator is the ratio of the volume of the loading chamber to the boiler power. To put it simply, how many times a day will you have to approach the boiler to load fuel. For steel boilers this figure is usually higher - on average 1.5-2.5 l/kW versus 1.1-1.4 l/kW for cast iron boilers - therefore, loading is carried out less frequently.

Be sure to make sure that there is an emergency cooling system and clarify the principle of its operation. This system may be needed if the boiler overheats and water boils in the heat exchanger. Boilers with a separate emergency cooling circuit are safer; if emergency cooling is achieved by abruptly draining water from the heat exchanger and replacing it with cold water, make sure that the boiler is resistant to thermal shock.

Protection against burns is an important indicator, especially if access to the boiler room is open to strangers or children. A useful option is heat-insulated firebox handles, protective casings and grates, and thermal insulation of the hottest surfaces of the boiler.

Thermal protection of boilers - required condition security

Wood boilers - installation requirements

Efficient and safe operation of a wood-burning boiler is impossible without correct installation. How to install a boiler with your own hands without violating safety rules?

Installation location

Any wood-burning boiler consumes a fairly large amount of air during operation, so for low-power boilers that can be installed in common areas at home, doing supply and exhaust ventilation, and with a boiler power of more than 50 kW, it is necessary to install a separate boiler room with a useful room volume of 8 cubic meters or more. Wood-burning boilers are installed on a solid, level base with a fireproof coating - concrete, tile, porcelain stoneware. The walls must also be lined with non-combustible materials. The boiler room is equipped with forced ventilation.

Chimney requirements

The chimney for a wood-burning boiler is made of of stainless steel, ceramics or thick-walled metal pipe. Optimal choice chimneys are made of stainless steel sandwich type. They are easy to assemble from various elements– pipes held together with clamps, roof penetrations, unloading platforms. When bending such a chimney, bends are used at a certain angle. It is allowed to exhaust the boiler chimney not through the roof, but through the wall of the building. The height of the straight part of the chimney for stable draft in the boiler must be at least 6 meters for a 16 kW boiler and at least 10 meters for a 32 kW boiler, with a pipe diameter of 200 mm.

Service and maintenance

It is also necessary to clarify the service and warranty conditions for the selected boiler model, the proximity of service centers and the possibility of calling specialists for installation and repair. It may happen that servicing a cheaper model will cost much more than analogues from well-known companies with service centers in large cities.

Video - self-installation of solid fuel boilers

Wood-burning boilers for heating a house after installation are connected to a water heating system. For uninterrupted operation of the system, you can additionally install a tank-heater on electric heating elements, in this case you will not have to add firewood during a night's rest or absence from home.

2 Affordable price 3 High level of efficiency (91%)

Solid fuel boilers – alternative way heating of private houses. Electric models consume a lot of electricity, so the effectiveness of their use (especially over large areas) is very questionable. Gas boilers are more justified in this regard, but require the supply of the appropriate type of fuel to the house, which is not always possible. It is in such cases that it is very difficult to overestimate the benefits of stoves, the combustible material for which is firewood, coal and other solid elements.

The current market realities are such that potential consumers are presented with hundreds, if not thousands, of models of heating boilers for every taste: long-burning and pellet, classic and pyrolysis. It's quite natural what to do a good choice in such a situation it is very, very difficult. To simplify the situation a little, we have prepared for you a rating of the 18 best solid fuel heating boilers in six different categories.

The best long-burning solid fuel boilers

The advantage of long-term heating boilers over others is clear from the name: the duration of solid fuel burning in them when the furnace is fully loaded is two to three days, and in other cases (depending on the type of fuel) it reaches five or even twelve days. At the same time, a volume of thermal energy sufficient to heat the entire provided area is released on an ongoing basis. They are economical, but have low efficiency and cause a lot of trouble to maintain.

3 NMK Magnum KDG 20 TE

Profitable price
Country Russia
Average price: 48,000 rub.
Rating (2019): 4.8

A typical representative of long-burning boilers from a Russian manufacturer, which was created specifically for the climatic conditions of our vast country. Unlike many other contenders (according to manufacturers’ recommendations), it uses exclusively coal for heating, which burns out within five days with an efficiency of around 75-80 percent. This is not much, but when heating with other fuels, for example, wood, the situation looks much more sad. Users' feelings from the operation of this boiler are generally positive: the design is serviceable, it is unpretentious in maintenance, and in terms of power in general it is the “golden mean”. I am very pleased with the existing system for regulating fuel combustion, albeit primitive.

Advantages:

• product domestic production, which explains the favorable price;
• good workmanship;
• the presence of a heating control system (the connection between the control links is carried out in a chain).

Flaws:

• the need to observe a strictly defined position of the air damper (with a gap of five millimeters) for proper operation of the boiler.

2 Stropuva Mini S8

The optimum ratio of price and quality. User selection
Country: Lithuania
Average price: 56,500 rub.
Rating (2019): 4.8

Lithuanian heating boiler, highly rated by users. In fact, the manufacturing company Stropuva continues and naturally reaps the benefits of the system built during the Soviet Union. The Mini S8 boiler is compact, made in the form of a “barrel”, but it is very heavy to move, which causes some problems with installation. Its efficiency is associated, first of all, with its type - long burning of one load of coal can provide heat for two to five days. There are also no complaints about the quality - everything is done reliably, neatly (which is not so important in boilers) and evokes some semblance of true admiration. But there is still one miscalculation - the shagreen lining is practically impossible to remove carbon deposits, which most often form above the firebox door.

Advantages:

• very high quality execution;
• economical heating of premises - one stack of firewood is enough for 12-20 hours of burning; coal – up to five days;
• good balance between price and quality;
• the ability to connect additional circuits, heating elements, and other systems.

Flaws:

• beautiful, but impractical shagreen covering;
• difficulty in moving due to the large weight of the “mini-model”.

To complete the picture and clarify what pros and cons this or that type of solid fuel boiler has, let us turn to the comparison table:

Boiler type	pros	Minuses
Classical	Extremely simple and reliable technology Low price compared to other types Any available type of fuel can be used	– Low efficiency – Inability to accurately adjust the coolant temperature – High sensitivity to moisture content of flammable materials
Long burning	When loaded with coal, the boiler can operate for up to five days. Using wood fuel the operating time is two days Complete energy independence	– Lack of water temperature regulators in the system – Increased requirements for fuel quality – Typically very low efficiency
Pyrolysis	High efficiency Possibility of process adjustment Long intervals between placing flammable materials (up to 12 days) High reliability and workmanship	– Electrical connection required – Without lining, the combustion chamber is very sensitive to raw fuel – If the lining is not at the proper level, the chamber walls burn out and the boiler fails
Pellet	High efficiency Complete process control via electronic control	– High price and large dimensions of boilers – High cost and shortage of fuel – Requires a power connection

The best inexpensive solid fuel classic boilers

Classic heating boilers are by no means rare devices in use. They are successfully used by people for heating private houses or for installation in houses on summer cottage. By the way, inexpensive models ideal for the second rather than the first option. They are by no means bad, but their characteristics very often turn out to be overestimated, which leads users to disappointment after the first attempts to use them.

3 EVAN WARMOS TT-18

High power rating
Country Russia
Average price: 32850 rub.
Rating (2019): 4.4

Solid fuel boiler of Russian origin. Not bad for being a heat source for a country house, but questionable for use in a private room. Its whole problem lies in its overstated characteristics - the rated power of 18 kilowatts is designed to heat areas up to 120 square meters, but the effect of heat transfer is practically not felt. The real and most effective heating threshold is no more than 60 square meters. Solid fuel, with optimal regulation of the dampers, it burns out in 60-90 minutes, after which the boiler quickly cools down and, if this moment is missed, requires re-ignition. And you can’t forget about the functions of a stoker either. The result is logical: the model is quite capricious, but if desired, you can always find a compromise that suits both parties.

Advantages:

• very simple installation of the boiler;
• acceptable quality of the case;
• capable of working on wood, coal and peat.

Flaws:

• inflated data on heated areas;
• the need to select the optimal position of the damper to prevent excessive fuel consumption or interference with normal combustion.

2 ZOTA Dymok-M AOTV-12M

Optimal balance of characteristics
Country Russia
Average price: RUB 18,870.
Rating (2019): 4.6

An ideal model for installation in a summer cottage. Small, but with decent power potential; unprepossessing, but it makes up for it with its original functionality. 12 kilowatts of thermal power released during complete combustion of combustible material is enough to heat 80 square meters of area. Even 70% efficiency does not spoil general impression from work. This version of the oven is combined, so it can be used for heating and electrical element(TEN). At the top of the body there is a hob - a pleasant addition to the main function and acceptable characteristics.

Advantages:

• the presence of a hob is a nice addition;
• efficient heating of the area declared by the manufacturers;
• possibility of connecting a thermal electric heater;
• The coolant is heated to a temperature of 95 degrees Celsius.

Flaws:

• mediocre appearance;
• a little overpriced.

1 Lemax Forward-16

Best price
Country Russia
Average price: 16,500 rub.
Rating (2019): 4.8

16 kilowatts of power of the Lemax Forward-16 boiler is enough to heat administrative and domestic premises, private residential buildings and even cottages, through independent or forced (with the installation of a pump) circulation of the coolant through the heating water system. This is one of the most successful examples small but productive installations with an uncharacteristically high (about 75-80 percent) level of efficiency. The simple design contains a solution to many operational problems. From the point of view of a technologist, such measures as, for example, “padding” the heat exchanger with channels to increase the ultimate tensile strength look redundant, but are justified from the point of view of durability of use. Such a boiler can last a good seven to nine years, provided that all correct operation measures are followed without exception.

Advantages:

• Availability additional elements, which have a positive effect on the durability of the installation;
• optimal cost with acceptable quality;
• a fairly high (atypical) level of efficiency;
• the ability to connect a pump to increase the coolant circulation rate;
• the possibility of converting the boiler to work with gas (carried out by installing a gas burner device).

Flaws:

Boilers: classic solid fuel boilers of premium class

More expensive classic boilers are installations of a completely different level. Unlike their budget “brothers”, they have more high percent Efficiency, power, as well as indicators of overall reliability (not always, but as a rule). The disadvantages of inexpensive classics, expressed in the deliberate overestimation of characteristics, are absent here, however, the typical disadvantages classical systems are fully manifested.

Optimal cost
Country: Japan
Average price: 35990 rub.
Rating (2019): 4.8

Kentatsu ELEGANT-03 is a modified model heating boiler, which took into account all the nuances and errors of previous installations. It is reliably known that they, in turn, did not have effective cooling and allowed the boiler to overheat. In this version, this is a water grate cooler, and, as practice shows, it copes with the assigned task flawlessly. On the front wall of the cast iron body there is a thermometer showing the real temperature of the coolant water. A controversial step towards ensuring ergonomics was the division of the boiler into sections. On the one hand, it has increased effective area within the model, but on the other hand, this negatively affects the terms of service.

Advantages:

• the model took into account the mistakes of the past, including with active cooling;
• Availability of equipment for self-service;
• low price;
• high quality and durability of the cast iron body;
• presence of a thermometer on the front wall.

Protherm Beaver 50 DLO is a real monster among the elite, a Slovak-made product that will definitely appeal to anyone who wants to have a high-performance heating boiler.

The Slovaks did not come up with anything new to preserve useful thermal energy. Based on known physical laws, facts and practice, they simply stuffed thermal insulating glass wool under the cast-iron body, thereby reducing heat losses. As a result of this simple step, efficiency skyrocketed to a crazy 90 percent. By updating the standard shape of the heat sinks, they were able to increase the volume of the combustion chamber. Thus, with one load you can achieve a completely comfortable temperature in a room of up to 350 square meters. This is largely due to the rated power of 39 kilowatts.

Advantages:

• high technical characteristics;
• adequate build quality;
• large heated area;
• low heat losses due to the presence of insulating material;
• presence of an air regulator;
• availability of maintenance tools in the kit.

Flaws:

• not detected.

The best solid fuel pyrolysis boilers

The action of pyrolysis, or gas generator, boilers is based on the combustion of wood gas released from smoldering firewood under the influence of temperature. When passing through the nozzle, the gas burns out, which contributes to the formation of a small amount of ash and soot. Coefficient useful action such boilers reach 85 percent. The burning time of one load ranges from 5 to 12 hours. The disadvantages include high price and special requirements for fuel - only dry wood is needed for heating.

Country: Austria
Average price: RUB 370,216.
Rating (2019): 4.8

An Austrian boiler capable of maintaining a comfortable temperature throughout the day. It all depends on the selected power: in the nominal combustion mode, firewood and briquettes last no more than four hours. As the indicator decreases, the rate of complete combustion of the bookmark decreases. According to experts, an important difference between this model and domestic ones is the occurrence of a real pyrolysis process, as opposed to ordinary afterburning. Perhaps the only drawback of the boiler is the need for a constant connection with CAS - a specialized heat storage tank. The supplied control panel is responsible for the operation of the systems.

Advantages:

• presence of a control panel – complete automation of processes;
• after pyrolysis, the process of afterburning the exhaust gases occurs - complete exhaustion of fuel;
• high rated power.

Flaws:

• failure of the control panel deprives the user of the ability to manipulate processes;
• very high cost.

Country: Czech Republic
Average price: 171,900 rub.
Rating (2019): 4.9

Pyrolysis boiler of a serious European level, created in accordance with all current quality standards. Czech manufacturers decided to release a line of automatic control units, which simultaneously made life easier and more difficult for themselves and their users. The fact is that “automation” is a delicate thing, and in some particularly unfavorable cases (due to accidents) it can easily fail. Repairing and setting up a control system on a boiler of this level is expensive, which often causes bewilderment and an angry reaction from people. Perhaps this is the only significant drawback of the system, because in other components it is almost perfect.

Advantages:

• the presence of an automatic control system for temperature and operating parameters;
• presence of emergency, boiler and boiler sensors;
• burning of wood stock is 12 hours, briquettes – 15-17 hours;

• expanded complete base.

Flaws:

• adjustment and repair automatic system control, in case of failure, will cost the consumer a pretty penny.

The best solid fuel pellet boilers

Pellet boilers are large installations equipped with bunkers for granulated wood waste. The sizes of such granules range from 5 to 70 millimeters in length and from 6 to 10 millimeters in thickness. This is the longest-lasting method of heating a room. The duration of heating directly depends on the volume of the adjacent bunker, and can be 2-12 days. The main disadvantage of such boilers is scarce fuel. Granulated pellets are not sold everywhere, so there is a high probability of equipment downtime.
