18 best solid fuel boilers

Solid fuel boilers - an alternative way to heat private homes. Electric models consume a lot of electricity, so the effectiveness of their use (especially in large areas) is very doubtful. Gas boilers in this regard are more justified, but they require the supply of an 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 furnaces, for which firewood, coal, and other solid-state elements serve as combustible material.

The current realities of the market are such that hundreds, if not thousands, of heating boiler models for every taste are presented to the potential consumer: long burning and pellet, classical and pyrolysis. It is quite natural that making a good choice in such a situation is very, very difficult. In order to simplify the situation a bit, we have prepared for you a rating of the 18 best solid fuel heating boilers in six different categories.

The best solid fuel boilers long burning

The advantage of heating boilers of long heating over others is clear from the name: the duration of burning solid fuel in them with a full load of the furnace is two or three days, and in other cases (depending on the type of fuel) it reaches five or even twelve days. In this case, on a permanent basis, the amount of thermal energy is allocated, sufficient to heat the entire area provided. They are economical, however, have low efficiency and cause a lot of trouble to maintain.

3 NMK Magnum KDG 20 TE

A typical representative of long-burning boilers from a Russian manufacturer, which is specifically designed for the climatic conditions of our vast country. Unlike many other applicants (as recommended by manufacturers), it accepts only coal for heating, which burns down within five days with an efficiency of around 75-80 percent. This is not much, but when heating with other fuel, for example, firewood, the situation looks much more sad. The users' feelings about the operation of this boiler are generally positive: the construction is in good condition, it is unpretentious to maintain, and in terms of power as a whole - the “golden mean”. Very pleased, albeit primitive, but the existing system for regulating the combustion of fuel.

Advantages:

• domestic product, which explains the favorable cost;
• good workmanship;
• the presence of a heating control system (the connection between the adjusting links is made by a chain).

Disadvantages:

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

2 Stropuva Mini S8

Lithuanian heating boiler, highly rated by users. In fact, the manufacturer Stropuva continues and regularly reaps the benefits of the system built during the Soviet era. The Mini S8 boiler is compact, made in the form of a “barrel”, however it is very heavy to move, and therefore there are some problems with the installation. Its efficiency is connected, first of all, with the type - a long burning of one laying of coal is capable of producing heat for two to five days. There are no complaints about the quality either - everything is done reliably, carefully (which is not so important in boilers) and causes some semblance of true admiration. But one miscalculation is still there - the shagreen lining is practically not amenable to the removal of soot, which is most often formed above the firebox door.

Advantages:

• very high quality performance;
• profitability for space heating - one stack of wood is enough for 12-20 hours of burning; coal - up to five days;
• good balance of price / quality ratio;
• the ability to connect additional circuits, heating elements, and other systems.

Disadvantages:

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

1 Buderus Logano G221-25

The German coppers from the Buderus company is a standard of quality and working capacity on heating of spacious rooms. Despite Eastern European production, they easily endure the difficult conditions of the harsh Russian winter, have a fairly high level of efficiency (85 percent), and do not require a large amount of fuel. If the circulating pressure of the coolant is not enough, you can easily “pick up” the pump to the Buderus Logano G221-25, to which savvy users resort. Heating takes place very quickly, and cleaning the furnace does not cause any difficulties. Thus, 20-kilowatt models can heat a room of up to 200 square meters. And what a 25-kilowatt boiler is capable of - judge for yourself.

Advantages:

• the volume fire chamber - contains in itself logs up to 68 centimeters long;
• nice design;
• excellent workmanship and impeccable design reliability;
• high energy efficiency;
• unpretentious to maintain and easy to install.

Disadvantages:

• high price.

The best cheap solid fuel classic boilers

Classic heating boilers - devices are not rare in use. They are successfully used by people for heating private houses or for installation in houses on the summer cottage. By the way, low-cost models are ideal for the second, rather than for the first option. They are by no means bad, but their characteristics are very often too high, which leads users to disappointment after the first attempts at use.

3 EVAN WARMOS TT-18

Solid fuel boiler of Russian origin. Not bad to become a heat source for a country house, but it is doubtful for use in private premises. His whole misfortune lies in the overstated characteristics - the nominal power of 18 kilowatts is designed for heating areas up to 120 square meters, but the effect of heat transfer is almost not felt. The real and most efficient heating threshold is no more than 60 squares. Solid fuel, with optimal control of the dampers, burns in 60-90 minutes, after which the boiler cools quickly and, if this moment is omitted, it requires re-kindling. Yes, and about the functions of the stoker also can not forget. The result is logical: the model is rather “capricious”, but if you wish, you can always find a compromise that suits both parties.

Advantages:

• very simple installation of the boiler;
• acceptable housing quality;
• able to work on wood, coal and peat.

Disadvantages:

• overestimated data on heated areas;
• the need to select the optimum position of the valve in order to prevent excessive fuel consumption or obstacles to normal combustion.

2 ZOTA Dymok-M AOTV-12M

The ideal model for installation on the summer cottage. Small, but with decent power potential; unsightly, but overlapping with its original functionality. 12 kilowatts of heat output released during the complete combustion of combustible material is enough to heat 80 square meters. Even a 70 percent efficiency does not spoil the overall impression of the work. This variant of the furnace is combined, therefore, it can also use an electric element (heating element) for heating. In the upper part of the body there is a hob - a pleasant addition to the main function and acceptable characteristics.

Advantages:

• the presence of a hob as a nice addition;
• efficient heating declared by manufacturers of the area;
• the ability to connect a thermal electric heater;
• The heating medium is heated to a temperature of 95 degrees Celsius.

Disadvantages:

• mediocre appearance;
• slightly over priced.

1 Lemax Forward-16

16 kilowatts of Lemax Forward-16 boiler capacity is enough to heat the administrative and residential levels, private residential houses and even cottages, by means of independent or forced (with pump installation) circulation of the heat carrier through the heating water system. This is one of the most successful examples of small but productive installations, having an unusually high (about 75-80 percent) level of efficiency. A simple design contains a solution to many operational problems. From the point of view of the technologist, such measures as, for example, “podbivka” heat exchanger channels to increase the ultimate resistance to rupture, look redundant, but justify themselves in terms of durability of use. Such a boiler is able to serve a good seven to nine years, provided that all measures of correct operation are followed without exception.

Advantages:

• the presence of additional elements that positively affect the durability of the installation;
• optimal cost with acceptable quality;
• high enough (non-typical) level of efficiency;
• possibility of connecting the pump to increase the rate of circulation of the coolant;
• the possibility of retrofitting the boiler to work with gas (carried out by installing a gas burner device).

Disadvantages:

• no serious flaws were found.

Boilers classic solid fuel boilers premium

More expensive classic boilers - installation of a completely different level. Unlike their budget "brothers", they have a higher percentage of 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 drawbacks of classical systems are fully manifested.

3 Kentatsu ELEGANT-03

Kentatsu ELEGANT-03 is a modified boiler model, which took into account all the nuances and errors of previous installations. It is reliably known that those, in turn, did not have effective cooling and allowed the boiler to overheat. In this version, the water cooler of the grate became such, and, as practice shows, it copes with its task impeccably. A thermometer is located on the front wall of the cast-iron case, showing the actual temperature of the water coolant. The breakdown of the boiler into sections has become a controversial step towards ensuring ergonomics. On the one hand, the usable area inside the model has increased, but on the other hand, this has a negative effect on the terms of service.

Advantages:

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

Disadvantages:

• Breakdown of the boiler into sections complicates the process of repair and maintenance in the event of a breakdown.

2 Bosch Solid 2000 B SFU 12

Bosch products confidently occupy high positions in all areas of the manufacturer’s activity and a similar trend is also observed in the boiler segment. Bosch Solid 2000 B SFU 12 is a low-power (for elite installations) version of the boiler, which is very popular with users for its good heating capacity. The main "feature" of the model is the functionality of use: it can be leading or combined with a gas boiler to increase the efficiency of space heating. So, one of the users successfully used the installation for heating a small workshop, and, as practice has shown, there were no problems with handling. Heat from one load was kept in the system for three to four hours, which indicates an unequivocal expediency of installation.

Advantages:

• high quality and body, and the internal device;
• acceptable efficiency (84-85 percent);
• positive feedback from users;
• easy maintenance;
• possibility of combination with gas boilers.

Disadvantages:

• low rated power (13.5 kW).

1 Protherm Beaver 50 DLO

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

Slovaks did not invent anything new for the preservation of useful heat energy. Relying on the well-known physical laws, facts and practice, they simply stuffed heat-insulating glass wool under the cast-iron case, thereby reducing heat losses. Due to this simple step, efficiency has soared to a crazy 90 percent. By updating the standard form of heat sinks, they were able to increase the volume of the combustion chamber.Thus, from one load you can catch up with quite comfortable temperature in a room of up to 350 squares. This is largely due to the nominal power of 39 kilowatts.

Advantages:

• high performance;
• proper build quality;
• extensive heated area;
• low heat loss due to the presence of insulating material;
• the presence of an air regulator;
• the presence in the kit servicing tool.

Disadvantages:

• not detected.

The best solid fuel pyrolysis boilers

The effect of pyrolysis, or gas-generating, boilers is based on the combustion of wood gas emitted from smoldering firewood under the action of temperature. When passing through the nozzle, the gas burns out, which contributes to the formation of small amounts of ash and soot. The efficiency of such boilers reaches 85 percent. The burning time of one load is from 5 to 12 hours. The disadvantages include the high price and special requirements for fuel - only dry wood is needed for heating.

3 Wirbel BIO-TEC 35

Austrian boiler capable of maintaining a comfortable temperature for the whole day. It all depends on the selected power: in the nominal mode of burning wood and briquettes is not more than four hours. With a decrease in the rate of complete combustion of the bookmark decreases. According to experts, the important difference between this model and domestic models lies in the course of this pyrolysis process, as opposed to ordinary afterburning. Perhaps the only drawback of the boiler is the need to permanently connect to the CAS - a specialized heat storage tank. For the functioning of the systems, the supplied control panel is responsible.

Advantages:

• availability of a control panel - full process automation;
• after pyrolysis, the process of afterburning of exhaust gases takes place - full production of fuel;
• high rated power.

Disadvantages:

• failure of the control panel deprives the user of the possibility of manipulating processes;
• very high cost.

2 Bourgeois-K STANDARD-20

The heating capacity of the “Bourgeois-K” series boilers was repeatedly questioned - they say, a value of 20 kilowatts does not mean absolutely nothing, since it does not heat the declared area of ​​200 square meters. Someone from the users stands on the side of manufacturers, someone - claims about the inability. Nevertheless, the endless disputes formed a good excitement around the model range, so the technique does not experience a lack of attention. The burning time of one bookmark in it is about ten hours. In terms of price, this boiler is noticeably inferior to “foreign” models, which is its main and irrefutable advantage.

Advantages:

• cost is lower than competitors;
• high thermal power and the corresponding heating capacity;
• the duration of burning bookmarks;
• low consumption of combustible material.

Disadvantages:

• huge excitement around the possible discrepancy between the characteristics of the declared information.

1 Wattek PYROTEK 36

Pyrolysis boiler of a serious European level, created according to all applicable quality standards. Czech manufacturers decided to launch a line of automatic-controlled installations, which at the same time made their lives and users easier and more complicated. The fact is that “automation” is a delicate thing, and in some particularly unfavorable cases (as a result of incidents) it can easily fail. Repair and adjustment of the control system on a boiler of such a level is expensive, which often causes bewilderment and an angry reaction from people. Perhaps this is the only major drawback of the system, because in other components it is almost perfect.

Advantages:

• the presence of the system of automatic temperature and regime parameters;
• availability of emergency, boiler and boiler sensors;
• burning of the mortgage of wood makes 12 hours, briquettes - 15-17 hours;
• high quality assembly materials;
• extended complete base.

Disadvantages:

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

The best solid fuel boilers pellet type

Pellet boilers are overall 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 way to heat the room. The duration of heating depends on the volume of the adjacent bunker, and may 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.

3 ZOTA Pellet 100A

One such boiler is more than enough to heat the whole building, where there is a water heating system with a pre-installed pump for forced circulation. Manipulation of all aspects of the system is reduced to an electronic control panel. This system is truly unkillable - unless, of course, the user is faced with the opposite goal. The rated power of the boiler reaches 100 kilowatts, but it can be lowered by controlling the air supply. In the same way regulated and feed pellets into the furnace. The only and most significant drawback of the system is overweight structures. 829 kilograms - this unit weighs so much, which is not so easy to move even within the scope of the delivery task, not to mention the final installation.

Advantages:

• the price corresponds to the stated parameters;
• fuel supply to the combustion chamber is carried out by a screw mechanism;
• electronic control system controls all aspects of the functionality of the installation;
• high rated power.

Disadvantages:

• very large weight designs.

2 ACV TKAN 100

Almost complete analogy of the downstream model, ACV (ACV) TKAN 100 is one of the best pellet boilers on the world market. The screw feed mechanism, the presence of an electronic control system, the rated power of 100 kilowatts - all this is not new. The main difference between the two models lies in the price and weight parameters - the ACV weighs only 595 kilograms (significantly less than the opponent), but costs one and a half times more. Nevertheless, relying on the words of experts and those rare users who dealt with this boiler (mainly in large enterprises), it can be concluded that its quality parameters are very high.

Advantages:

• not the greatest weight of the structure;
• high level of efficiency (90%) and rated power;
• the presence of an electronic control system that exercises full control over the processes;
• screw feed mechanism.

Disadvantages:

• high price.

1 PELLUX COMPACT

Albeit not large, but the high-performance model of a pellet boiler PELLUX COMPACT boasts a high value of efficiency - as much as 92 percent at an optimal level of work. All this and much more is the result of the booming activities of the Swedish firm NIBE, specializing in the production of solid fuel boilers. To obtain such a value of efficiency allows the installed burner, which has a positive effect on reducing the consumption of granulated pellets while increasing the release of thermal power. Another clear advantage is the presence in the combustion chamber of the replacement mesh, which allows you to turn the pellet boiler into a pyrolysis by replacing the pellets with dry logs.

Advantages:

• economical burner, which allowed to reduce fuel consumption and increase heat output;
• availability of automated electronic control;
• the possibility, if necessary, to switch to another type of fuel - from wood pellets to wood and back;
• high level of efficiency;
• high build quality.

Disadvantages:

• no serious flaws were found.

The best double-circuit solid fuel boilers

Double-circuit boilers benefit from the already considered models in the sense that they are used not only to heat the house, but also to provide hot water. This is one of the best solutions for private homes located in areas where it is impossible to connect the gas and often there are interruptions in electricity. Dual-circuit solid fuel boilers are economical to operate and many models fully meet the needs of users in heat and hot water.

3 Bourgeois-K T-50A-2K

One of the most powerful solid fuel bypass pyrolysis type boilers. Designed for heating large areas up to 500 m²It can be used for heating of cottages and industrial premises and providing hot water in them. Due to the complete autonomy of the boiler it can be used in places where electricity is not available. Firewood, waste wood processing production and coal of any brand can be loaded into the furnace. Fuel consumption is very economical - on one tab the boiler works up to 10 hours.
