Autonomous heating largely outperforms centralized heating. It can be turned on and off at your own discretion, you can adjust the temperature and significantly save during operation. The main thing is to choose the most optimal heating method - gas or solid fuel.
Features of gas boilers
Models running on "invisible" fuel have two undeniable advantages - they take up little space and are very affordable. They are ideal for homes and even apartments where there is no room to store firewood, briquettes or coal. Due to the closed combustion chamber and forced draft that draws air from the street, there is no need to install the boiler in a separate room. Its small size allows the unit to be hung almost anywhere.
Gas boilers have a large selection of double-circuit models. They not only heat the room, but also provide the house with hot water. Such devices are very economical: there is no need to spend extra money, because the water heats up simultaneously with the general heating system.
Solid fuel boilers: pros and cons
As a rule, solid fuel models are chosen by the owners of non-gasified houses. The most profitable are units that use wood waste - sawdust and shavings. In addition, many boilers can simultaneously "consume" different types of fuel.
Of particular interest are models with an additional stove function. The upper surface is made of cast iron. It can have removable rings. During cooking, such solid fuel boilers save electricity or gas.
It is believed that gas models are more practical, as they do not need to be constantly looked after. However, you can choose a machine equipped with a hopper and automatic loading. Ignition, fuel supply and operation of the circulation pump are regulated without human control. Many models can be connected to a room thermostat and use it to adjust the temperature. With one coal load, the boiler can operate for up to 24 hours.
Choosing solid fuel boilers, you should know that they have one significant drawback: before installation, it is necessary to equip a special boiler room with a good exhaust hood.
Universal combined models
If you can't decide between the two types of boilers, you can purchase a combined unit. It works well both on gas and wood or coal.
However, it should be understood that the installation of such a boiler will not be cheap - at least two to three times more expensive than conventional models. But in the future, such devices are very practical in operation and allow you to save a lot.
Before choosing a specific model, it is necessary to calculate all possible costs: purchase, installation, fuel consumption. For example, gas boilers are much cheaper, but a tie-in to a gas pipeline can cost a lot. On the other hand, building a storage facility for coal and firewood can also be problematic. Therefore, only after weighing all the pros and cons, you can provide your home with heat for many years.
Domestic wood-fired boilers have replaced traditional heating stoves. The main advantage of wood-fired boilers made in Russia is unpretentiousness to the quality of the fuel used and operating conditions, low cost (in comparison with European units).
Wood-fired boiler manufacturers in Russia
The domestic consumer has already been able to form a definite opinion about domestic and industrial solid fuel boilers for wood, Russian production. Like any other heating equipment, the products have their advantages and disadvantages.The types of wood-fired heating boilers produced in Russia can be divided into several classes:
- By the principle of work.
- The presence of a DHW circuit.
- Purpose.
- Heat exchanger type.
Domestic firewood boilers of the following designs are offered:
- Russian-made gas-fired wood-fired 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 for long burning are offered by several companies at once. The advantage of "our" equipment is the reduced consumption of firewood and longer work from one tab. - Boilers with a conventional design - heat generators of this type, according to the principle of operation, resemble an ordinary wood-burning stove. The difference is that the structure is equipped with a water circuit. It is allowed to connect to a conventional radiator heating network with or from a coolant.
Which domestic wood-fired boiler to choose
Wood-fired hot water heating boilers of Russian production 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 in their characteristics to Western counterparts. 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 firebox goes 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 (KChM plant) can be distinguished separately. The models are intended for domestic use.
Wood-burning boilers of high power, for industrial purposes, from all of the above manufacturers, are manufactured only by KZKO LLC.
The cost of Russian wood-burning boilers
The cost for domestic wood heating equipment is approximately 2-3 times less than for European counterparts, which explains its demand among the consumer. The price is influenced 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, approximately the same power and identical parameters. Productivity from 15-20 kW.
- PARTNЁR (Koster) - boilers of low 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 (Kirovsky plant)- the highest cost of boilers among analogs of this class, 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 within 44-48 thousand rubles.
- Zota -, in terms of the quality and automation of boilers, is as close as possible to European units. The cost of a 20 kW boiler will be about 33 thousand rubles.
Solid fuel boilers are an alternative way to heat private houses. Electric models consume a lot of electricity, so the effectiveness of their use (especially over large areas) is very doubtful. Gas boilers in this regard are more justified, however, they 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, for which firewood, coal and other solid-state elements serve as a combustible material.
The current realities of the market are such that hundreds, if not thousands, of models of heating boilers for every taste are presented to a potential consumer: long burning and pellet, classic 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 little, we have prepared for you a rating of the 18 best solid fuel heating boilers in six different categories.
The best solid fuel boilers for long burning
The advantage of long-term heating boilers over others is clear from the name: the duration of solid fuel burning in them with a full load of the furnace 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 is released on an ongoing basis, sufficient to heat the entire provided area. They are economical, but have low efficiency and cause a lot of hassle in maintenance.
3 NMK Magnum KDG 20 TE
Profitable price
Country Russia
Average price: 48,000 rubles.
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 applicants (according to the recommendations of manufacturers), it accepts exclusively coal for heating, which burns out within five days with an efficiency in the region of 75-80 percent. This is not much, however, when heating with other fuels, for example, wood, the situation looks much more sad. The feelings of users from the operation of this boiler are generally positive: the design is serviceable, unpretentious in maintenance, and in terms of power as a whole, it is a “golden mean”. It is very pleasing, albeit primitive, but the existing fuel combustion control system.
Advantages:
- a domestically produced product, which explains the favorable cost;
- good workmanship;
- the presence of a heating control system (the connection between the control links is carried out 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
The optimum ratio of price and quality. User Choice
Country: Lithuania
Average price: 56,500 rubles.
Rating (2019): 4.8
Lithuanian heating boiler highly appreciated 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", however, it is very heavy to move, in connection with which there are some problems with installation. Its efficiency is associated, first of all, with the type - long burning of one coal tab is capable of producing heat for two to five days. There are also no complaints about the quality - everything is done reliably, accurately (which is not so important in boilers) and causes some semblance of true admiration. But there is still one miscalculation - the pebbled cladding practically does not lend itself to removing carbon deposits, which most often form above the firebox door.
Advantages:
- very high quality performance;
- efficiency when heating premises - one stack of firewood is enough for 12-20 hours of burning; coal - up to five days;
- good balance of value for money;
- the ability to connect additional circuits, heating elements, and other systems.
Disadvantages:
- beautiful but impractical pebbled finish;
- difficulty in moving due to the large weight of the "mini-model".

1 Buderus Logano G221-25
Best quality
Country: Germany
Average price: 154580 rub.
Rating (2019): 4.9
German boilers from the Buderus company are the standard of quality and efficiency for heating spacious rooms. Despite the Eastern European production, they easily endure the difficult conditions of the harsh Russian winter, have a fairly high level of efficiency (85 percent), and also do not require a large amount of fuel. If the circulating pressure of the coolant is not enough, you can easily "hook up" a pump to the Buderus Logano G221-25, which is what smart users resort to. Heating takes place very quickly, and cleaning the firebox is straightforward. Thus, 20-kilowatt models are capable of heating a room with an area of up to 200 square meters. And what a 25-kilowatt boiler is capable of - judge for yourself.
Advantages:
- volumetric firebox - accommodates logs up to 68 centimeters long;
- nice design;
- excellent workmanship and irreproachable design reliability;
- high energy efficiency;
- unpretentious in maintenance and easy to install.
Disadvantages:
- high price.
The best inexpensive solid fuel classic boilers
Classic heating boilers are devices that are by no means rare in use. They are successfully used by people for heating private houses or for installation in houses at their summer cottages. By the way, inexpensive models are ideal for the second rather than the first option. They are by no means bad, but their characteristics are very often overestimated, which leads users to disappointment after the first attempts to use.
3 EVAN WARMOS TT-18
High rated power
Country Russia
Average price: 32,850 rubles.
Rating (2019): 4.4
Solid fuel boiler of Russian origin. Not bad to become a heat source for a country house, but doubtful for use in a private room. All his trouble lies in the overestimated characteristics - the rated power of 18 kilowatts is designed for heating 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 squares. Solid fuel, with optimal regulation of the dampers, burns out in 60-90 minutes, after which the boiler cools down quickly and, if this moment is missed, it requires re-ignition. And you can't forget about the functions of a stoker either. 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 quality of the case;
- able to work on wood, coal and peat.
Disadvantages:
- overestimated data on heated areas;
- the need to select the optimal position of the damper in order to prevent excessive fuel consumption or obstructions to normal combustion.
2 ZOTA Dymok-M AOTV-12M
Optimal balance of performance
Country Russia
Average price: 18 870 rubles.
Rating (2019): 4.6
The ideal model for installation in a summer cottage. Small, but with decent power potential; unsightly, but covering it with its original functionality. 12 kilowatts of thermal power released during the complete combustion of combustible material is enough to heat 80 square meters of area. Even 70% efficiency does not spoil the overall operating experience. This version of the furnace is combined, therefore it can also use an electric element (heating element) for heating. The top of the cabinet houses the hob - a nice addition to the main function and acceptable performance.
Advantages:
- the presence of a hob as a pleasant addition;
- efficient heating of the area declared by the manufacturers;
- the ability to connect a thermal electric heater;
- heating of the coolant is carried out to a temperature of 95 degrees Celsius.
Disadvantages:
- mediocre appearance;
- slightly overpriced.
1 Lemax Forward-16
Best price
Country Russia
Average price: 16,500 rubles.
Rating (2019): 4.8
16 kilowatts of power of the Lemax Forward-16 boiler is enough to heat the premises of the administrative and household levels, private houses and even cottages, by means of 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 of small but productive installations with an uncharacteristically high (about 75-80 percent) level of efficiency. The uncomplicated design contains a solution to many operational problems. From the point of view of the technologist, such measures as, for example, "tamping" the heat exchanger with channels to increase the ultimate tensile strength, look redundant, but justify themselves from the point of view of durability of use. Such a boiler can serve for a good seven to nine years, provided that all measures of correct operation are followed without exception.
Advantages:
- the presence of additional elements that have a positive effect on the durability of the installation;
- optimal cost with acceptable quality;
- sufficiently high (atypical) level of efficiency;
- the ability to connect a pump to increase the circulation rate of the coolant;
- the possibility of converting the boiler to work with gas (carried out by installing a gas burner device).
Disadvantages:
Boilers classic solid fuel boilers of premium class
More expensive classic boilers are installations of a completely different level. Unlike their budget "counterparts" 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 deliberate overestimation of characteristics, are absent here, however, the typical disadvantages of classic systems are fully manifested.
3 Kentatsu ELEGANT-03
Optimal cost
Country: Japan
Average price: 35,990 rubles.
Rating (2019): 4.8
Kentatsu ELEGANT-03 is a modified model of a heating boiler, which took into account all the nuances and mistakes 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 grates became such, and, as practice shows, it copes with the assigned task flawlessly. A thermometer is located on the front wall of the cast-iron body, showing the real temperature of the water coolant. A controversial step towards ensuring ergonomics was the division of the boiler into sections. On the one hand, the usable area inside the model has increased, but on the other hand, this negatively affects the conditions of service.
Advantages:
- the model took into account the mistakes of the past, including those with active cooling;
- the presence of equipment for self-service in the kit;
- low price;
- high quality and durability of the cast iron body;
- the presence of a thermometer on the front wall.
Disadvantages:
- splitting the boiler into sections complicates the process of repair and maintenance in the event of a breakdown.
2 Bosch Solid 2000 B SFU 12
The optimum ratio of price and quality. Expert selection
Country: Germany
Average price: 51977 rub.
Rating (2019): 4.9
Bosch products confidently occupy high places in all areas of the manufacturer's activity and in the boiler segment a similar trend is also observed. 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 ability. The main "feature" of the model lies in the functionality of use: it can be a leading one or combined with a gas boiler to increase the efficiency of heating the premises. 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. The heat from one load was kept in the system for three to four hours, which indicates the unambiguous expediency of the installation.
Advantages:
- high quality of both the case and the internal structure;
- acceptable efficiency (84-85 percent);
- positive user reviews;
- ease of maintenance;
- the possibility of combining with gas boilers.
Disadvantages:
- low rated power (13.5 kW).
1 Protherm Beaver 50 DLO
The best indicator of efficiency (90.2%). High boiler output (39 kW)
Country: Slovakia
Average price: 109,500 rubles.
Rating (2019): 5.0
Protherm Bober 50 DLO is a real monster among the elite, a product of Slovak production, which will definitely appeal to everyone who wants to have a high-performance heating boiler.
Slovaks did not come up with anything new for the preservation of useful heat energy. Based on the well-known physical laws, facts and practice, they simply stuffed heat-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 bring quite a comfortable temperature into a room with an area of up to 350 square meters. This is largely due to the rated power of 39 kilowatts.
Advantages:
- high technical characteristics;
- adequate build quality;
- extensive heated area;
- low heat losses due to the presence of insulating material;
- the presence of an air regulator;
- the presence of a service tool in the kit.
Disadvantages:
- not detected.
The best solid fuel pyrolysis boilers
The action of pyrolysis, or gas generating, boilers is based on the combustion of wood gas released from smoldering wood under the influence 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
High level of efficiency (91%)
Country: Austria
Average price: 370216 rubles.
Rating (2019): 4.8
Austrian boiler capable of maintaining a comfortable temperature throughout the day. It all depends on the selected power: in the nominal mode of burning wood and briquettes it is no more than four hours. With a decrease in the indicator, the rate of complete combustion of the bookmark decreases. According to experts, an important difference between this model and domestic ones lies in the course of the real pyrolysis process, as opposed to ordinary afterburning. Perhaps the only drawback of the boiler is the need for a permanent connection to the CAS - a specialized heat storage tank. The supplied control panel is responsible for the functioning of the systems.
Advantages:
- the presence of a control panel - full automation of processes;
- after pyrolysis, the process of afterburning of exhaust gases occurs - complete production of fuel;
- high rated power.
Disadvantages:
- failure of the control panel deprives the user of the ability to manipulate processes;
- very high cost.
2 Bourgeois-K STANDARD-20
Affordable price
Country Russia
Average price: 55470 rub.
Rating (2019): 4.8
The heating capacity of boilers of the Bourgeois-K series has been repeatedly questioned - they say that a value of 20 kilowatts does not mean absolutely nothing, since it does not heat the declared area of 200 square meters. Some of the users take the side of the manufacturers, someone claims to be unable. Nevertheless, endless disputes have 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 the "foreign" models, which is its main and irrefutable advantage.
Advantages:
- the cost is lower than that of competitors;
- high thermal power and corresponding heating capacity;
- burning time of the bookmark;
- low consumption of combustible material.
Disadvantages:
- huge excitement around the possible inconsistency of the characteristics of the declared information.
1 Wattek PYROTEK 36
Best rated thermal power (36 kW)
Country: Czech Republic
Average price: 171,900 rubles.
Rating (2019): 4.9
A pyrolysis boiler of a serious European level, built in accordance with all current quality standards. Czech manufacturers decided to release a line of automatic control units, which at the same time made life easier and more difficult for themselves and their users. The fact is that "automation" is a delicate thing, and in some especially unfavorable cases (due to accidents) it can easily fail. Repair and adjustment of the control system on a boiler of this level is expensive, which often causes bewilderment and an angry reaction of people. Perhaps this is the only significant drawback of the system, because in other components it is almost perfect.
Advantages:
- the presence of an auto-control system for temperature and operating parameters;
- availability of emergency, boiler and boiler sensors;
- burning wood mortar is 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 pellet boilers
Pellet boilers are large-scale installations equipped with bunkers for granulated wood waste. The sizes of such granules are from 5 to 70 millimeters in length and from 6 to 10 millimeters in thickness. This is the longest-lasting way to heat 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. Granular pellets are not sold everywhere, so there is a high likelihood of equipment downtime.
3 ZOTA Pellet 100A
The optimum ratio of price and quality
Country Russia
Average price: 379,000 rubles.
Rating (2019): 4.9
One such boiler is more than enough to heat an entire building, where there is a hot water heating system with a pre-installed pump for forced circulation. The manipulation of all aspects of the system is reduced to an electronic control panel. This system is truly indestructible - unless, of course, the opposite goal is set before the user. The nominal power of the boiler reaches 100 kilowatts, but it can be reduced by regulating the air supply. The supply of pellets to the firebox is regulated in the same way. The only and most significant drawback of the system is the overweight of the structure. 829 kilograms - this is how much this unit weighs, which is not so easy to move even within the scope of the delivery task, let alone the final installation.
Advantages:
- the price corresponds to the declared parameters;
- the fuel is supplied to the combustion chamber by a screw mechanism;
- an electronic control system controls all aspects of the functionality of the installation;
- high rated power.
Disadvantages:
- very heavy weight of the structure.
2 ACV TKAN 100
Optimal set of parameters in a lightweight body
Country: Belgium
Average price: 554,000 rubles.
Rating (2019): 4.9
Almost complete analogy of the downstream model, ACV TKAN 100 is one of the best pellet boilers on the world market. The screw feeder, the presence of an electronic control system, a rated power of 100 kilowatts - all this is not new. The main difference between the two models lies in the parameters of price and weight - ACV weighs only 595 kilograms (noticeably less than the opponent), but costs one and a half times more. Nevertheless, based on the words of experts and those rare users who dealt with this boiler (mainly at large enterprises), we can conclude 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 ongoing processes;
- auger fuel feeding mechanism.
Disadvantages:
- high price.
1 PELLUX COMPACT
Best compact model. Highest efficiency level (92%)
Country: Sweden
Average price: 220 941 rub.
Rating (2019): 5.0
Albeit not large, but a high-performance model of the PELLUX COMPACT pellet boiler can boast a high efficiency value - as much as 92 percent at an optimal level of operation. All this and much more is the result of the vigorous activity of the Swedish company NIBE, which specializes in the production of solid fuel boilers. The installed burner allows obtaining such a value of efficiency, which has a positive effect on reducing the consumption of granular pellets while increasing the release of thermal power. Another clear advantage is the presence of a replacement grid in the combustion chamber, which allows you to turn a pellet boiler into a pyrolysis boiler by replacing the pellets with dry logs.
Advantages:
- economical burner, which made it possible to reduce fuel consumption and increase heat output;
- availability of automated electronic control;
- the ability, if necessary, to switch to another type of fuel - from pellets to firewood and vice versa;
- high level of efficiency;
- high build quality.
Disadvantages:
- no serious flaws were found.
The best double-circuit solid fuel boilers

The high cost of operating gas-fired heating equipment and the inaccessibility of this type of energy carrier for small settlements lead to an increase in the popularity of solid fuel boilers.
The use of coal and wood is becoming an excellent alternative to gas. However, a huge assortment of equipment models causes certain difficulties in choosing.
In order to determine which boiler is best to buy for specific conditions, it is worth conducting a comparative analysis. That is, taking equipment similar in performance, consider several models from different manufacturers. So, for example, each of the boilers of the proposed TOP review can be used to heat premises with a total area of about 200 sq. m and has its own advantages.

Model Description
The purpose of the Protherm Bober 20 DLO solid fuel boiler is to heat residential and utility rooms with a total area of up to 170 sq. m. Additional installation of the boiler will allow to provide hot water supply with its help. The model is equipped with a cast-iron sectional heat exchanger and can serve for 10-15 years with fairly intensive use. At the same time, it has quite an attractive appearance due to the coloring of the body with heat-resistant red enamel.
Advantages and disadvantages
The main advantages of the boiler are its high operating efficiency and fuel economy. You can load firewood into the firebox no more than 2 times a day. At the same time, the equipment is able to serve for a long time, without succumbing to deformation and corrosion, thanks to the use of cast iron in the manufacture of both the furnace and the heat exchanger.
Among the disadvantages of the equipment, it is worth noting that cleaning is not very convenient and the need to adapt to the features of traction control. When loading firewood, the furnace door interferes a little. And to move the Beaver 20 DLO is heavier than a number of analogues due to its relatively large mass.
Installation features
The boiler can be installed both in residential premises and in utility rooms (corridors, basements, boiler rooms). In this case, it is necessary to provide an inflow of combustion air and a system for the removal of combustion products. In addition, for safe operation, the equipment must be installed on a non-combustible base. The installation of the boiler must be carried out by specialized organizations that have the appropriate permission.
Price
In the domestic market, the minimum cost of a boiler is about 45 thousand rubles. The maximum amount that you have to pay for its purchase can reach 52 thousand.
Main characteristics:
- the use of coke, coal or dry wood;
- Efficiency in the range of 75–78%;
- equipment performance when operating on wood, coke and coal 23 kW, 26 kW and 24 kW, respectively;
- outdoor installation;
- the length of the logs placed in the firebox: up to 41 cm;
- dimensions: 110 × 60.5 × 92 cm;
- boiler weight: 278 kg.
Description
The G221-25 boiler is completely autonomous, and its operation does not depend on voltage surges, or on gas or electricity cuts. It is equipped with an open combustion chamber, which means that air is drawn directly from the room and flue gases are removed by the draft of a vertical chimney.
The operating time of the equipment on one fuel load reaches several hours - it can be increased by switching to an economical mode of operation or by additionally installing a loading hopper. And due to the stylish painting with heat-resistant blue enamel, the boiler of the new generation looks great in the interior of any room where it is installed.
Advantages and disadvantages
The main advantages of the model are the increased corrosion resistance of the body and heat exchanger material (cast iron), ease of use and increased dimensions of the furnace. In addition, for ease of use, the firebox door can be hung on both the left and right sides. And the disadvantages of the model can only be called a significant weight (310 kg) and a high cost.
Installation nuances
The boiler can be installed both separately and together with other types of heating equipment (gas, oil or electric) in residential, domestic and industrial premises. And Buderus Logano G221-25 can be used in pumping and gravitational water heating systems.
The equipment can be installed independently, even without welding. However, due to the need to comply with a number of rules, this is not recommended. And the installation should be carried out by qualified specialists familiar with the process of installing solid fuel boilers in heating systems.
Price
The average cost of a boiler is approximately 80 thousand rubles, depending on the store. If you wish, you can find this model for 75 thousand.
Main characteristics:
- the ability to work on wood, coal, wood waste and briquettes;
- power reaching 24 kW;
- Efficiency at the level of 82–92%;
- heated area: up to 250 sq. m;
- log length: no more than 55 cm;
- wood moisture: up to 50%;
- boiler dimensions: 50 × 80 × 118 cm;
- weight: 310 kg.
Basic properties of the model
The equipment has a modern stylish appearance, which is emphasized by the red color of the body. The boiler furnace door is equipped with a convenient handle, which increases the reliability of opening and closing. This model takes air from the room and expels it into the atmosphere through a vertical chimney.
Due to the design features, Bourgeois-K Modern-24 can operate for several hours after one load. Although, with the help of a regulator of air flow into the furnace, a high-speed heating mode is also provided, which allows you to quickly heat a cold room.
Advantages and disadvantages
The main advantages of the boiler, according to user reviews, are the economical use of firewood - about half that of other solid fuel boilers. Heating the maximum possible area serviced by the boiler requires no more than 40 kg of firewood per day. It is also worth noting the complete independence of the equipment from such energy sources as gas or electricity, and its compact size, which allows the device to be installed in any convenient and suitable place for this.
However, Modern-24 also has drawbacks. For example, the need to install a pipe with a height of at least 8 meters for the normal removal of combustion products. And the grates of the equipment burn out too quickly and need to be replaced. In addition, according to the owners of the boilers, sometimes the gates of the devices clog up too quickly.
Installation features
The boiler and related equipment should only be installed by professionals in accordance with the project documentation and the current installation regulations. They must also ensure that the device is started up and repaired in the event of a malfunction. The rooms for the installation of boilers must be provided with a sufficient amount of light; if necessary, they must be equipped with good artificial lighting.
Price range
Depending on the store chosen, the equipment has a different cost. For example, with an average price of about 80 thousand rubles, the minimum amount demanded by sellers starts from 71,700 rubles. the limiting values of the cost can reach 95 thousand rubles.
Main characteristics:
- work on solid fuels of various types, including not only firewood, but also coke and coal;
- capacity sufficient for heating approximately 200 sq. m of area, and the component for various types of coolant (firewood, coal and coke) 16, 18 and 20 kW, respectively;
- floor mounting type;
- compact dimensions: 110 × 60.5 × 82 cm;
- Efficiency: within 70–78%;
- the size of the logs placed in the firebox is about 35 cm;
- device weight: 237 kg.
Model Description
Traditionally painted in blue with heat-resistant enamel (which, thanks to its anti-corrosion properties, will last no less than the boiler itself, that is, about 15 years), it has an attractive appearance and is able to decorate with itself both residential and household, and even utility rooms. The cast-iron body of this model is strong enough to ensure a high degree of fire safety, and high heat transfer guarantees comfortable temperature conditions in the house throughout the entire cold period.
The long burning process of logs in the boiler furnace is obtained using a special regulator that increases or decreases the air flow. Due to this, the equipment, which can be used in both pressure and gravitational heating systems, can work for several hours on one portion of firewood. Together with it, it is allowed to include equipment on other types of energy carriers in the water heating system - gas, electricity and even liquid fuel. For this, the boiler is equipped with a receiving hopper of a significant size, designed for loading large logs.
Advantages and disadvantages
The boiler has a lot of advantages. These include the minimum time for heating the ambient air and an attractive appearance. And when equipped with a bunker, the equipment does an excellent job with almost semi-autonomous work, that is, it can heat premises, almost without requiring the presence of a person.
But in the standard configuration, the boiler cools down quickly, regardless of the mode, as evidenced by the reviews of buyers who have already used Buderus Logano G221-20. In addition, the cost of the equipment is too high compared to its functionality. And during operation in a hot water heating system, the boiler is best supplemented with other heating equipment, for example, gas or electricity powered.
Mounting
When installing this Logano model, there is no need to use welding - it is quite simple to connect to the existing heating system using ordinary tools. True, in this case, a number of recommendations should be followed that only an experienced specialist can handle. After connecting and putting the equipment into operation, the user is required to comply with a number of rules:
- do not change the design of the smoke exhaust system;
- do not start up the boiler without sufficient water;
- use only approved types of fuel;
- do not reduce the size of the ventilation openings in the room.
Price
Many buyers who choose heating equipment note the high cost of the G221-20. The minimum amount you have to pay for it is 70,600 rubles. However, there are offers on the market that are much more expensive - up to 104 thousand rubles.
Main characteristics:
- maximum area of heated rooms: 150 sq. m;
- power regulation capabilities: within 30-100%;
- thermal efficiency of the model: up to 83%;
- using fuels such as coal, firewood, wood waste or pellets;
- built-in electrical equipment: heating element with a capacity of 6 kW;
- it is possible to install a gas or pellet burner;
- maximum dimensions of firewood: diameter up to 100 mm, length up to 500 mm;
- device dimensions: 74 × 34 × 50 cm;
- total weight without firewood: 98 kg.
Model Description
The compact dimensions and appearance of the equipment facilitate its placement in any room of a residential building or household premises. At the same time, the boiler is quite powerful and efficient due to the presence of a heat exchanger and the possibility of complete extinguishing of the flame in the tube sheet. The time of its operation on wood can vary from 60–90 minutes to several hours, which determines the fuel economy.
If, however, one of the pellet or gas burners produced by the same Teplodar brand is installed on the boiler, it is possible to ensure the operation of the boiler in the temporary absence of solid fuel. The equipment is also capable of operating on electricity, for which a 6-kilowatt heating element is already built into its design.
Advantages and disadvantages
The main advantage of Kupper OK 15 is considered by most consumers to be its low cost, combined with decent quality. The efficiency of the heating device and its maintainability are also highly appreciated. Using the boiler, you can put firewood in its firebox no more than 2 times a day. You can also use other types of energy, the transition to which for this model is quite simple.
The disadvantages include fuel consumption, which is significantly increased compared to other, more expensive solid fuel boilers of other brands. Another disadvantage of the model is its rather complicated installation.
Installation features
Most boilers operating in a hot water heating system are relatively easy to install, and the call of a specialist for their installation is rather related to the need for experience in such work. However, for the installation of Kupper OK 15, you will have to turn to professionals also because of the complexity of its connection with pipes. In this case, one should be guided by the rules for connecting the electric power supply and the PUE.
Price
The cost of a boiler from different suppliers may differ by almost one and a half times. The minimum price for equipment is 22,820 rubles. The maximum reaches 35,210 rubles.
The work of a wood-burning boiler on gas fuel (natural gas) excites craftsmen. The combination of firewood and natural gas adds to the comfort and economic efficiency of heating systems. I will say right away - the issue of transferring a wood-burning boiler to gas fuel is not disclosed in this article due to its harmfulness and danger. But, combining firewood and gas is possible and necessary. It is really comfortable and economical.
- Combination of two separate boilers "gas" and "wood" in the heating system
Wood burning gas fired boiler
Technically (correctly and safely), it is impossible to improve a wood-burning heating unit to the state of "omnivorous" (gas and wood). Gas is an explosive poisonous fuel, the free handling of which leads to dire consequences. The rules for the operation of gas equipment cannot be ignored.
The fantasies of folk craftsmen for gas heating are limited by the word "forbidden". Legislators, manufacturers, designers and operators are all reinsured on the topic of safety. To climb over the OFFICIAL GAS "FORBIDDEN" is practically unrealistic.
Officially, for the transfer of a wood-burning boiler to gas fuel, a project is required, coordinated with the relevant local control services - gas, fire, utilities, etc. Installation with the subsequent commissioning of the heating equipment takes place in accordance with the current legislation. Behind simple words, there is a deep engineering problem.
Already at the initial stage of transferring a wood-burning boiler to gas fuel, the whole idea breaks down on the discrepancy between the designs of the combustion chambers and the ventilation systems of wood and gas heating equipment. Wood and gas fuels are in different states of aggregation, they have different specific calorific value, so it requires completely different ventilation modes of the combustion chamber and, most importantly, different sizes of this very chamber.
A gas boiler is a complex product. The body of a gas boiler has been calculated and tested over the years. Its dimensions are determined by the established norms and rules for burning gas fuel. Height, width, distance of the torch to the hearth and to the roof, tightness of the combustion chamber, turbulization of gas flows, quality of ventilation, coordination of the operation of automation units, etc. - all parameters are verified by the manufacturer, who is fully responsible for the safety of his brainchild. There are not so many manufacturers of gas boilers.
Wood-burning boilers "rivet" all and sundry. No responsibility. If only the wood-burning fire would be warm and burning. Unlike a gas boiler, the design of a wood-burning boiler is not limited by anything, except for one thing - the desire to "squeeze" more heat out of the wood. The body of the wood-fired boiler has additional devices that create turbulence and slow down the speed of movement of gaseous combustion products. Simply put, in a wood-burning boiler, gas flows are inhibited in order to increase the efficiency of the wood-burning boiler as a whole. That, in relation to the rules for the operation of gas heating equipment - is strictly prohibited! All gas boilers work only on direct draft! Any devices that slow down the ventilation rate of the furnace (combustion chamber) of a gas boiler are prohibited. Any tubular heat exchangers, turbulators, dampers, additional ventilation "pockets" and so on are prohibited for gas heating equipment.
And now let's try to mentally put a gas burner into a wood-burning boiler and remember that a wood-burning boiler has a combustion chamber (firebox) much larger, because it is focused on firewood. What will this give in combination with insufficiently effective ventilation? Right. Excess combustion products in the boiler drum. And if we add here the presence of a loading door and other holes through which this excess of combustion products can enter the heated room (furnace), then it becomes quite clear why no controller will give permission to operate such a monster.
P.S. There are many things that make the conversion of a wood-burning boiler to gas extremely unprofitable. But, the most important thing is the unjustified risk of operating a converted heating unit. At the official level, the conversion of a wood-burning boiler to gas fuel will never be encouraged. Heating technicians, officially, do not convert wood-fired boilers into gas burners. Because they know - all fiscal services (fire, gas, and utilities) - will always struggle with modified and homemade gas heating equipment.
As for unauthorized construction and independent (illegal) transfer of a wood-burning boiler to gas fuel, then everyone will disown such a "kulibin" at once. A person trying to independently transfer a wood-burning boiler, stove or stove to gas heating violates a whole bunch of laws and exposes his safety and the safety of the people around him to unjustified risk.
Combined gas-wood boilers
From the point of view of the development of modern technology - combined gas-wood boilers have the right to life. Combined gas-wood boilers existed even under the Union. But, the Soviet combined gas-firewood boilers always worked on a separate power supply - either gas or firewood (solid fuel). And so that both at once is a clear know-how. In the modern electronic world, it is not difficult to implement any technical idea. Here, only - the benefit is small. In the performance of modern amateurs, combined gas-wood boilers are either not safe, or too expensive, or inconvenient and cumbersome to operate.
Combination of separate boilers "gas" and "wood"
The combination of two separate boilers "gas" and "wood" in one heating system is the best option. If the boilers are located in different combustion rooms, then this is generally ideal.
