Rating of solid fuel boilers with water loop: Top 10 models for the house for quality and price

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

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

The market is full of different options - which one to choose?

Rating TOP-10 best solid fuel boilers with a water loop

How to choose and what to pay attention to?

Experts recommend to pay attention to the following points:

• The principle of operation and the number of circuits. If it is necessary to provide DHW, then it is worth choosing two-circuit options. If there is a need to maintain heat for a long time without refueling, then long-burning boilers are the most optimal option.
• Type of fuel - Not all boilers are universal, and the price of fuel varies greatly. Here it all depends on the preferences and capabilities of the consumer.
• Power. Properly chosen power will provide a comfortable temperature in the entire room, with its lack of temperature readings will be noticeably lower than expected.

Types of solid fuel boilers with water loop

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

• Universal - operate on any fuel with the possibility of connecting a gas burner. They are equipped with a quality safety system that prevents burning or stopping operation without operator control.
• Long burn - operate on a candle principle, which provides uninterrupted heating from 24 hours to a week. However, due to the peculiarities of design, they are quite expensive.
• Pyrolysis - With two fuel chambers, which consume fuel and combustion gas. Have a very high efficiency, give less thermal pollution.
• Traditional - Similar in principle to the usual furnace, do not require electricity, are available and relatively cheap.

Advantages and disadvantages of solid fuel boilers with water loop

Advantages of water heating boilers are high quality of assembling, long lifetime, economical fuel consumption, and indiscriminateness of regular inspections.

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

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

Also, they need to be regularly loaded with fuel - on average, every 5-6 hours, except for long combustion variants and models with automatic supply of wood or coal.

Water loop - what is it and why is it necessary?

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

Heat loss in them will be very high, and the temperatures often do not reach even the optimal for living and prolonged stay.

In addition, in homes with stove heating, it is not uncommon for corners to freeze. The water circuit will avoid this problem.

How to choose the capacity of a solid fuel boiler with a water loop

The choice of power of the boiler with a water loop is not practically different from the usual. The easiest calculation is to divide the heated output by the specific power of the boiler.

The obtained result is to be reduced by a factor of 10.. The result is the starting point in the selection of boiler output with a water circuit.

In cold regions, it is worth adding 20% to the number to account for heat losses and climatic features.

V - volume of the room, T - difference between the optimal temperature in the room and the minimum outdoors.

K is the heat loss coefficient, which depends on the room. For modern structures with double-glazed windows it is 0.5, for wooden buildings - 4.

Which manufacturing company is better?

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

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

• Teplodar - Russian brand, works since 1997 and has its own unique patented technology. Each year the brand updates technopark, using for the production of heating equipment high quality machines of world brands.
• Zota - A relatively young brand that takes into account the climatic conditions of the countries where the heating equipment is supplied. They also take into account peculiarities of regular maintenance, which is not always possible due to the remoteness of residential areas from big cities and service centers. Supplied a large number of different modifications.
• Stropuva - is a company from Lithuania, founded in 2000. They own the patent for the candle-type combustion technology. Thanks to this technology long combustion boilers were developed. The release of products in Russia is carried out on a joint venture, thanks to the experience of domestic specialists the brand develops boilers optimized for the realities of the Russian climate.
