Models of solid fuel heating equipment are an excellent alternative to their counterparts operating on liquid or liquefied fuel. Recently, boilers designed for long burning have been in great demand. They are able to work offline for several tens of hours. When choosing the best modifications of the device, you should be guided by consumer reviews. The rating of equipment included in the top 5 most demanded models of 2016-2017 will greatly simplify the task.
It runs on solid fuel and is a good alternative to its counterparts running on natural gas, diesel or electricity. Such equipment is especially in demand in non-gasified areas or remote from regional centers, as well as where there are constant interruptions in the operation of power lines. Solid fuel are produced for both industrial and domestic use.
Varieties of solid fuel boilers
On the heating equipment market, boilers are presented in a wide range from different manufacturers. In turn, the 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 working conditions. Therefore, solid fuel can be divided into several categories:
Advice. Boilers with an efficiency of 83 - 90% have an optimal ratio of the volume of the fuel chamber / duration of combustion. At the same time, they operate at the maximum power declared by the manufacturer.
Boiler rating by fuel type
Solid fuel boilers are highly versatile. Models designed to operate on wood or coal can be used as fuel pellets or briquettes. Based on the technical characteristics of the equipment and feedback from specialists and ordinary consumers, you can make a rating of the best models.
Stropuva S 40
A long-burning boiler that runs on wood, coal or wood briquettes takes the first place in this rating. The equipment of the Lithuanian-Russian company STROPUVA has the highest efficiency equal to 95%. An impressive volume of the firebox of 320 dm. cub. holds 50 kg of fuel. Depending on the operating mode, one load 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 operate on pellets or coke. Its design provides for one heating circuit, which makes it only used for the heating system. The power of the device is 40 kW, the liquid temperature is 85 ° C, and the working pressure is 2 bar.
Zota Pellet 25
The boiler is designed to work on wood pellets and takes the second place in the rating. The products of the domestic manufacturer are equipped with an LCD display, which displays all the necessary information: the current state, setting the operating mode, errors, etc. The automation system is capable of monitoring and controlling both the equipment itself and secondary devices. For example, it can control up to five circulation pumps for heating and underfloor heating. The pellet boiler has a high efficiency equal to 90%, its power of 25 kW is capable of effectively heating 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 furnace loading system. This function significantly increases the duration of burning and the 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, and the maximum log length should not exceed 68 cm. High efficiency of 90% and power from 10 to 20 kW compensate for minor disadvantages. A heat exchanger made of cast iron has a high heat transfer coefficient, which ensures rapid heating of the carrier to the required temperature. The device can operate on wood, coal and coke.
Protherm Beaver 50 DLO
The cast iron boiler from the Slovak manufacturer is ranked fourth. It 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 an insulating material between the furnace and the equipment body.
Teplodar Kupper OK30
The products of the domestic manufacturer are in fifth place. This is due to the relatively low efficiency of 84%. Due to the high power of 39 kW, it is able to heat the liquid to operating temperature in 20 minutes. It is able to efficiently heat a house with an area of up to 300 sq. M. 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 sufficiently high place.
Advice. The boiler, equipped with a cast-iron heat exchanger, has a high degree of heat transfer and a service life, which increases its efficiency and reliability several times.
Boiler rating by price
The cost of heating equipment plays one of the key roles in choosing the required model of a solid fuel boiler for long-term burning. In each price segment, there are the best models that 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. In this class, there are models that are perfect for summer 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 sound insulation characteristics. Power of 30 kW allows to heat an area up to 270 sq. M. Autonomy of work at one full load - 12 hours, maximum water temperature - 90 ° C.
The second place is taken 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. Possesses high heat-insulating and sound-insulating properties. Fuel consumption is 6.8 kg / h. The only negative is that it works exclusively on wood.
Alpine Air Solidplus 4 ranks third. Easy to maintain and operate, boiler power - 26 kW, efficiency - 70%, water temperature: minimum - 30 ° C, maximum - 90 ° C, operating pressure - 3 bar. Powered by wood or coal.
Premium class
- First place. Biomaster BM-15 is equipped with an ash pan auto-cleaning system, the volume of the fuel chamber is from 200 to 400 liters, the efficiency is 95%, the power is 16 kW. High performance allows the boiler to be used in multi-storey buildings or hotels, industrial buildings, etc.
- Second place. Viessmann Vitoligno Its 30 kW power and 90% efficiency allow heating up to 399 sq. M. One download is enough for battery life up to 40 hours. The automation system ensures reliable and stable operation.
- Third place. Candle S. A distinctive feature is the burning of only the upper part of the fuel. One download provides up to 36 hours of work. Efficiency 85 - 90%, power from 5 to 35 kW, depending on the model. Working pressure - 180 kPa, coolant temperature 90 ° C, fuel consumption - 0.29 kg / h.
Solid fuel boilers efficiently heat single-storey and multi-storey private houses, industrial premises: workshops, warehouses, etc., as well as various institutions: schools, kindergartens, hospitals.
