Rating of solid fuel boilers with a water circuit: TOP 10 models for the home in terms of quality and price

Solid fuel boilers with a water circuit are able to heat both small apartments and large industrial premises.

They are optimal in those places where there is no central heating and gas mains.

The market is filled with various options - which one to choose?

Rating of the TOP 10 best solid fuel boilers with a water circuit

How to choose and what to look for?

Experts recommend paying attention to the following points:

• The principle of operation and the number of circuits. If it is necessary to provide hot water supply, then it is worth choosing double-circuit options. If there is a need for long-term maintenance of heat without refueling, then long-burning boilers are the best option.
• Fuel type - not all boilers are universal, and the price of fuel varies greatly. It all depends on the preferences and capabilities of the consumer.
• Power. Properly selected power will provide a comfortable temperature throughout the room, with its lack of temperature indicators will be noticeably lower than expected.

Types of solid fuel boilers with a water circuit

Boilers with a water circuit are divided into traditional, long-burning, universal and pyrolysis - depending on the type of combustion.

• Universal - operate on any fuel with the ability to connect a gas burner. They are equipped with a high-quality safety system that prevents fire or stoppage of work without operator control.
• long burning - work on the principle of a candle, which provides uninterrupted heating from a day to a week. However, due to the design features, it is quite expensive.
• Pyrolysis - with two fuel chambers that consume fuel and the gas formed during its combustion. They have very high efficiency, give less thermal pollution.
• Traditional - similar in principle to a conventional oven, not demanding on electricity, affordable and relatively cheap.

Advantages and disadvantages of solid fuel boilers with a water circuit

The advantages of boilers with a water circuit in high build quality, long service life, economical fuel consumption and undemanding to regular technical inspection.

Some models have high efficiency due to the recycling of combustion products. Most boilers are undemanding to install.

However, most of these boilers have a lower efficiency compared to other types of boilers..

They also need to be regularly loaded with fuel - on average, every 5-6 hours, with the exception of long burning options and models with automatic supply of firewood or coal.

Water circuit - what is it and why is it needed

The water circuit is a well-known heating system using radiators.. It is necessary in houses with a not very good layout, reduces heat loss from the window, evenly heats the room.

Heat losses in them will be very high, and temperatures often do not even reach the optimal ones for living and long stays.

In addition, corners often freeze in houses with stove heating.. The water circuit will avoid such a problem.

How to choose the power of a solid fuel boiler with a water circuit

The choice of power of a boiler with a water circuit is practically the same as a conventional one.. The simplest calculation is to divide the heated power by the specific power of the boiler.

The result obtained is reduced by 10 times. The result is the starting point in selecting the power of a boiler with a water circuit.

In cold regions, add 20% to the number to take into account heat loss and climatic features.

V is the volume of the room, T is the difference between the optimal temperature in the room and the minimum outside.

K is the heat loss coefficient depending on the room. For modern structures with double glazing, it is 0.5, for wooden buildings - 4.

Which manufacturer is the best?

Solid fuel boilers with a water circuit are supplied by Russian and foreign manufacturers.

Experts identify the following brands, whose equipment is the most optimal for Russian climatic realities:

• Teplodar is a Russian brand that has been operating since 1997 and has its own unique patented technologies. The brand annually renews the technopark, using high-quality machines of world brands for the production of heating equipment.
• Zota - a relatively young brand, taking into account the climatic conditions of the countries where heating equipment is supplied. They also take into account the features of regular maintenance, which is not always possible due to the remoteness of residential areas from big cities and service centers. They supply a large number of different modification components.
• Stropuva is a company from Lithuania in 2000. They own a patent for the technology of fuel combustion like a candle. Thanks to this technology, long-burning boilers have been developed. Production in Russia is carried out at a joint venture, thanks to the experience of domestic specialists, the brand develops boilers optimized for the realities of the Russian climate.
