The best solid fuel boilers - 2022

Solid fuel boilers are indispensable for heating a private house in the absence of a gas pipeline or connection to a central heating system. Their advantages are reliability and durability, ease of operation. Many models are independent of the power supply.

Gas or solid fuel boiler: differences

To make the right decision and purchase the necessary equipment, it is worth comparing the characteristics of these structures.

• Power. Gas boilers do not need to be constantly “feeded” manually; they can heat several houses at once. Solid fuel models, even the most modern ones, need to be periodically loaded with raw materials.
• Fuel. Solid fuel units have different alternatives (wood, coal, pellets), gas units need only one substance to be supplied.
• Service. Solid fuel equipment must be cleaned of ash and checked frequently. Gas does not need such cleaning; a preventive check is carried out once a year.
• Safety. Fires can occur during the operation of any type of equipment. Solid fuel boilers require a separate room, which reduces the risk of carbon monoxide poisoning in the event of a carbon monoxide leak.
• Mounting. Gas boilers are installed only by specialists, solid fuel boilers are allowed to be installed independently.
• Cost: The prices for these types of equipment do not differ much, the technical data is more important.

Varieties of boilers

According to the material of the heat exchanger

• Steel. Relatively inexpensive in price. They are light in weight and have a high degree of resistance to temperature extremes.
• Cast iron. Stronger and much more durable than analogues made of steel. However, a large temperature difference can adversely affect the brittle material.Another significant drawback of such a boiler is its heavy weight.

By type of fuel used

• Wood. An important principle when buying firewood: their moisture content should be minimal and not exceed 20% for a gas-generating boiler. In classic models, the use of wet firewood is acceptable, but not very desirable. Therefore, the place where the logs will be stored must be dry and well protected from moisture.
• Coal. When choosing which coal to use, you need to pay attention to its grade and fraction: they must comply with the technical conditions for the operation of heating equipment.
• Pellet. This type of fuel is pellets made from waste of various origins (peat, wood, agricultural). Such boilers are characterized by high efficiency, but they are not cheap, like the pellets themselves.
• On peat briquettes.
• Universal.

There are combined boilers that run on solid fuel and electricity or gas.

Air supply method:

• Volatile;
• Non-volatile.

According to the principle of fuel combustion

• Pyrolysis. The work is based on the combustion of gas released from firewood under the influence of high temperature. The wood is heated with minimal access to oxygen, resulting in the release of wood gas. Therefore, another name for such boilers is gas-generating. Gas is burned in a special chamber at a temperature of approximately 700 C. When using dry firewood, the efficiency of such equipment reaches 85%. However, they are harder to find and more expensive than regular ones. Another disadvantage is the high cost of the boiler and its complex multi-chamber design.
• Classic. They resemble an ordinary stove by burning fuel from the bottom up.Their advantages are simplicity of design, ease of operation, budget. Do not necessarily require high quality fuel. Disadvantages: frequent maintenance (it is necessary to add fuel 4-8 times a day), low efficiency (70-75%), low degree of power adjustment. Such a boiler will be a good option for heating a small house in which they do not live permanently.
• Long burning. It happens by analogy with a match or a candle: from top to bottom. Firewood laid in the boiler can burn up to three days, coal - up to five. Such efficiency is achieved due to the built-in electronic automation, turbine, special design of the combustion chamber. Pros: high productivity (efficiency of about 80%), environmental friendliness, independence from the quality of raw materials, automation of processes in energy-dependent models. Of the minuses, one can single out a rather big cost, the need to correctly observe the technology of loading fuel, the impossibility of reloading it.

By power:

• Up to 100 kW, suitable for heating a private house, cottage.
• Above 100 kW, industrial.

By type of fuel loading:

• Manual. The combustion process is also controlled manually. Boilers are inexpensive, have a simple design, but require constant supervision and care, it is more difficult to maintain the required temperature in them.
• Semi-automatic. A person lays the raw materials, and automation controls the combustion. It is possible to precisely adjust the temperature.
• Automatic. All processes are automated. Fuel is supplied to the boiler from a special bunker, often by means of a screw mechanism. Pellet or coal models are the most economical. The boiler has a high efficiency, can work autonomously for a long time, and is safe to use. Of course, this convenience comes at a cost.Other disadvantages are energy dependence, large equipment sizes.

According to the method of loading raw materials:

• Frontal (horizontal), as a rule, is typical for models with a cast iron heat exchanger. Ease of use when heating with wood. Possibility to report logs.
• Top (vertical). It prevails in boilers with a steel heat exchanger. The high efficiency of this method is due to the fact that it is characterized by lower combustion of the fuel; its upper part is being dried. At the same time, it is very important to carefully stack the logs in the firebox, otherwise there is a risk of reducing the efficiency.

Heating options:

• Single-circuit (only heat supply of the room is carried out).
• Double-circuit (not only heat the room, but also provide hot water).

Which company's equipment is better to buy

Popular models of both foreign and Russian production are presented on the heating appliance market today.

The best manufacturers of solid fuel boilers:

• Robert Bosch GmbH. Group of companies of German origin. Founded in 1886. Heating equipment is manufactured by the Bosch Thermotechnology division.
• Buderus. This firm was founded in Germany in 1731. Named after the name of the owner. It has enterprises for the production of equipment all over the world, including in Russia. Its products are in demand due to their high quality and reliability. In 2003, it became a brand of a group of companies.
• Protherm. The Czech manufacturer offers products certified according to EU standards.
• Stropuva. The Lithuanian company has been leading its history in Russia since 2006, offering consumers patented long-burning solid fuel units. Since 2011, products have been manufactured in St. Petersburg.
• Teplodar.The Russian manufacturer has been on the market since 1997. The company's products are not inferior to foreign counterparts and are cheaper.
• TPK Krasnoyarskenergokomplekt LLC produces boilers under the ZOTA brand, which includes five different lines.

How to choose a solid fuel boiler

A competent approach to the acquisition of such equipment is very important, therefore, if possible, you should consult with the seller of a specialized store.

Main selection criteria:

• Boiler power. There are models that are already focused on a certain area of ​​\u200b\u200bthe room. If the consumer buys a device designed for a smaller area than in reality, there is a risk that the boiler, working for wear, will quickly fail. An attempt to take equipment “with a margin”, that is, designed for a larger heating area than necessary, will also not be successful. The fuel simply will not burn out completely, remaining on the pipe in the form of resin, which will inevitably lead to a deterioration in the operation of the boiler. Universal calculation formula: 1 kW of energy will heat approximately 10 square meters. m. of housing. A number of other parameters: the number of windows and doors, the height of the ceiling will give additional information, which experts will help to analyze.
• Functionality. If the boiler is planned to be placed in the kitchen, then it makes sense to purchase it with a hob in the kit. Those who do not want to spend a lot of time servicing the device and laying raw materials into it should pay attention to long-burning boilers.
• The type of fuel to be used. As a rule, a model focused on a certain type of raw material can use an alternative. For example, coal-fired boilers can be loaded with wood, which, however, can reduce their power.Combustion features that affect the efficiency should be indicated in the technical data sheet.
• The volume of the combustion chamber: the smaller it is, the more often you will have to reload.
• Operating time at single loading. If it is important for the consumer not to approach the boiler every 4-5 hours, then it is better to choose a modern model, which needs only one load of fuel to work for several days.
• efficiency. This important indicator will tell you what part of the thermal energy is spent on heating the home. The lower it is, the more fuel consumption will be.
• What is the manufacturer's warranty period?
• Popularity of the model: there are a number of units that have proven themselves well with users.
• How much does the unit cost: domestic, as a rule, are cheaper than foreign ones. However, it is wrong to choose such equipment only at a low price: the technical parameters of a cheap boiler may not always be suitable for a particular situation.
