Especially for you, we have performed an analysis and compiled a rating of solid fuel boilers for long-term combustion. Data taken from the Internet sales market among the most popular Russian resources and electronic catalogs of climate technology for heating a private home, and tried to understand that, which are modern solid fuel boilers of long combustion, what is the difference between them and what are the advantages, and shortcomings.
To answer the question "How to choose a solid fuel long-burning boiler for the home?"- Let's start with that, what they are and what are their differences. What is hidden by definition - long-burning boilers, what is their difference from other solid fuel boilers installations?
Features of long-burning boilers
The first and most important fundamental difference is the method of fuel combustion. In these units, the technology of the combustion process differs significantly from the traditional classic scheme "bottom - up", as is customary in conventional furnaces and furnaces, and which ignites the entire portion of the fuel at once. In this case, everything happens exactly the opposite - "top - down", like a candle. A sustainable effect is achieved thanks to the telescopic design of the air flow distributor, which under the action of its own gravity presses on the flame and gradually shifts it down. As a result, the fuel slowly burns out in layers, along the entire height of the vertical combustion chamber starting from the upper level - the type of upper combustion boilers.
This design allows you to burn the material measured, evenly and better, increasing the efficiency and duration of one download. in addition, this feature allows: increase the service life of the unit, because the movement of the heat source in time reduces the "fatigue strength" of the steel heat exchanger compared to traditional furnaces, in which the cell is stationary and stationary; and completely abandon the use of additional heat accumulators.
Mechanical control of coolant temperature is carried out by a thermomechanical draft regulator (based on bimetal), which directly affects the air valve. Therefore, they can be used in systems, as with natural, and with forced circulation of the heat carrier.

And the second distinctive feature is their "unpretentiousness and omnipresence". And what is especially important in the heating system - the most economical fuel consumption. Example, to generate power to 20 kW, their performance is the type of fuel / one-time download, kg):
- firewood (? 50 kg);
- fuel briquettes - wood (? 110 kg) and peat (? 119 kg);
- coal - coal (? 145 kg) and anthracite (? 170 kg).
Due to specific design features - they are single-circuit, and have an efficiency of about 91-93%, one of the highest in its class. To completely burn a single bookmark of firewood, they need about 30 hours, and the amount of heat, released during the combustion of coal, enough for four days (for a private house with daily needs 150 kW / hour) depending on the temperature difference inside and outside the house. Their few drawbacks include only restrictions on the use of pellets, manual fuel loading and ash removal.
Yet, today solid fuel boilers are considered one of the most promising alternative sources of heating. Convincing evidence of this is the indicators of popularity ratings and the constant trend of growing interest in this segment of technology for heating a private home.

Market trends - choose the best solid fuel boiler for long burning 2016
Rating of popularity of solid fuel boilers of long burning is based on the analysis of statistical data of demand and consumer preferences of numerous users of the Russian Internet (shops and product catalogs). Carefully studying the rating data, choosing the best solid fuel boiler will not be difficult.
It is safe to say, that of all the variety of heating equipment, solid fuel models are confidently gaining popularity and gaining fans, especially those, who does not want to be price dependent, state of the economy and the vagaries of nature. Only last year, the growth of their segment has confidently reached 7%, while the most popular for heating homes before, remain: gases (73%), and gas with boiler (10%). Electric and condensing - in the amount of cover no more 8% market needs.
According to the type of energy, the rating of boilers is as follows:
- natural gas - 86%;
- solid fuel (all kinds) – 8%;
- electricity - 6%.
Useful power, kw:
- ? 15 – 18%;
- ? 16-25 – 53%;
- ? 26-35 – 16%;
- ? 36-50 – 7%.
The most popular models are top rated 10 solid fuel boilers
Which solid fuel boiler is better? Among the variety of brands, presented on the market, consumers prefer well-known brands, choosing reliability and quality for home heating. The best solid fuel boiler should be chosen under the brands: STROPUVA, lords, Candle, pereko, Heiztechnik, Buran, Gefest, SWaG, Metal tray, Viessmann.
Among these manufacturers, top ranking of the most popular models top (power, kw / maximum heating area, m2 to / dimensions: V?Sh?G, mm / weight, kg / price range, rub):
- STROPUVA:
- S40-U (40 / 300 / 2100?680?680 / 333 / 112636-126000);
— S30 U (30 / 240 / 1850?680?680 / 309 / from 109725);

We draw a conclusion from the rating, that the best solid fuel boilers for home heating are Lithuanian boilers Stropuva, The efficiency of which is 91,6%, all other firms no more 80%.
With all the positive benefits, at first glance - heating private homes with solid fuel boilers has its own specifics of operation, imposes certain restrictions on the owner and causes some difficulties, associated with their ongoing maintenance, procurement and storage of fuels. Unlike gas and electric, they constantly need to be manually "refueled", clean and remove ash as it burns out. They are unable to work autonomously more without human intervention 3-4 days in a row. The heating of the heating system and its entry into operation is longer. And that means, that you will not be able to leave your home unattended for long.
Yet, modern technologies are gradually increasing the efficiency and ease of use of these units, types and quality of fuel used, automated ways to download it are being developed and implemented, feed and remove ash, automation of control and management improves. Therefore, the consumer chooses solid fuel boilers for long-term combustion as the best alternative to expensive gas heating.
