The best solid fuel boilers - 2024

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 use. Many models differ in independence from 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 "fed" 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 only need one substance.
• Service. Solid fuel equipment must be cleaned of ash and checked frequently. Gas does not need such cleaning; a preventive check takes place once a year.
• Safety. Ignitions 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 leak.
• Mounting. Gas boilers are installed only by specialists, solid fuel ones are allowed to be installed independently.
• Cost: the prices for these types of equipment do not differ much, technical data is more important.

Varieties of boilers

By heat exchanger material

• Steel. Relatively inexpensive for the price. They are lightweight and highly resistant to temperature extremes.
• Cast iron. Stronger and much more durable than analogues made of steel. However, large temperature differences can adversely affect fragile material. Another significant drawback of such a boiler is its heavy weight.

By type of fuel used

• Wood burning. An important principle when buying firewood: their moisture content should be minimal and not exceed 20% for a gas-fired boiler. In classic models, the use of wet wood is acceptable, but not very desirable. Therefore, the place where the logs will be stored must be dry and reliably 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 operating conditions of heating equipment.
• Pellet. This type of fuel is pellets made from waste of various origins (peat, wood, agricultural). Such boilers are distinguished by high efficiency, but they are not cheap, as are the pellets themselves.
• On peat briquettes.
• Universal.

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

By air supply method:

• Volatile;
• Non-volatile.

By the principle of fuel combustion

• Pyrolysis. At the heart of the work is the combustion of gas released from wood under the influence of high temperature. The wood is heated with minimal oxygen access, resulting in the release of wood gas. Therefore, another name for such boilers is gas generating. The gas is burnt in a special chamber at a temperature of about 700 C. When using dry wood, the efficiency of such equipment reaches 85%. However, they are more difficult to find and more expensive than usual. Another disadvantage is the high cost of the boiler and its complex multi-chamber design.
• Classic. They resemble an ordinary stove with fuel combustion from the bottom up. Their advantages are simplicity of design, ease of use, and budget. They 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 power adjustment. Such a boiler would be a good option for heating a small house in which they do not live permanently.
• Long burning time. It happens by analogy with a match or a candle: from top to bottom. The firewood put into the boiler can burn up to three days, coal - up to five. This efficiency is achieved due to built-in electronic automation, a turbine, and a special design of the combustion chamber. Pros: high productivity (efficiency is about 80%), environmental friendliness, independence from the quality of raw materials, automation of processes in volatile models. Of the minuses, one can single out a rather large cost, the need to correctly observe the technology for loading fuel, the impossibility of reloading it.

By power:

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

By type of fuel loading:

• Manual. The combustion process is also manually controlled. Boilers are inexpensive, have a simple design, but require constant supervision and maintenance, it is more difficult to maintain the required temperature in them.
• Semi-automatic. A person lays in raw materials, and automatic equipment 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 hopper, often by means of a screw mechanism. Pellet or coal models are the most economical. The boiler has high efficiency, can operate autonomously for a long time, and is safe to operate. True, such convenience will cost more. Other disadvantages are volatility, large equipment sizes.

By 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 heated with wood. Possibility to report logs.
• Top (vertical). Dominated by boilers with a steel heat exchanger. The high efficiency of this method is associated with the fact that it is characterized by bottom combustion of the fuel; its upper part is being dried. At the same time, it is very important to carefully place the logs in the firebox, otherwise there is a risk of a decrease in efficiency.

If possible, heating:

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

Which company equipment is better to buy

On the market of heating devices, popular models of both foreign and Russian production are presented today.

The best manufacturers of solid fuel boilers:

• Robert Bosch GmbH. A group of companies of German origin. Date of foundation - 1886. The production of heating equipment is a division of Bosch Thermotechnology.
• Buderus. This company was founded in Germany in 1731. Named by the name of the owner. It has facilities 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 traces its history in Russia since 2006, offering consumers patented long-burning solid fuel units. Since 2011, products have been manufactured in St. Petersburg.
• Teplodar. Russian manufacturer, present on the market since 1997. The company's products are not inferior to foreign counterparts and are cheaper.
• LLC TPK Krasnoyarskenergokomplekt 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, it is worth consulting with the seller of a specialized store.

Main selection criteria:

• Boiler power. There are models already focused on a certain area of ​​the room. If a consumer buys a device designed for a smaller area than in reality, there is a risk that the boiler, which is working for wear, will quickly fail. An attempt to take equipment "with a margin", that is, designed for a larger heating area than needed, 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 about 10 sq. m. housing. A number of other parameters: the number of windows and doors, the height of the ceiling will give additional information, which will be analyzed by specialists.
• Functionality. If the boiler is planned to be placed in the kitchen, then it makes sense to purchase it with a hob included. Those who do not want to spend a lot of time on servicing the device and putting raw materials into it should pay attention to long-burning boilers.
• Fuel grade to be used. Typically, a raw material-oriented model can also use an alternative. For example, wood can be loaded into coal boilers, which, however, can reduce their power. Combustion features affecting the efficiency must 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 with one load. 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 only needs one load of fuel to operate for several days.
• Efficiency. This important indicator will tell you what part of the heat energy is spent on heating your home. The lower it is, the more fuel consumption will be.
• What is the warranty period provided by the manufacturer.
• The popularity of the model: there are a number of units that have proven themselves well among users.
• How much does the unit cost: domestic ones, 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 specific situation.
