Models of solid fuel heating equipment are an excellent alternative to their counterparts that run on liquid or liquefied fuel. Recently, boilers designed for long burning. They are able to work offline for several tens of hours. When choosing the best device modifications, you should be guided by consumer reviews. The rating of equipment included in the top 5 most popular models of 2016-2017 will greatly simplify the task.

Working on solid fuel, it is a good alternative to its counterparts running on natural gas, diesel fuel or electricity. Such equipment is especially in demand in non-gasified areas or remote from regional centers, as well as where there are constant interruptions in the operation of power lines. Solid fuels are produced for both industrial and domestic use.

Varieties of solid fuel boilers

In the heating equipment market, boilers are presented in a wide range from different manufacturers. In turn, companies have several lines of their equipment, of which there are many models. This circumstance greatly complicates the choice of the optimal variant for specific working conditions. Therefore, solid fuel can be divided into several categories:

Advice. Boilers with an efficiency of 83 - 90% have an optimal ratio of the volume of the fuel chamber / burning time. At the same time, they operate at the maximum power declared by the manufacturer.

Rating of boilers by type of fuel

Solid fuel boilers are highly versatile. Models designed to work on wood or coal can be used as fuel pellets or briquettes. Based on specifications ah equipment and reviews of experts and ordinary consumers, you can rank the best models.

Stropuva S 40

A long-burning boiler that runs on wood, coal or wood briquettes takes first place in this rating. The equipment of the Lithuanian-Russian company STROPUVA has the most high efficiency equal to 95%. The impressive volume of the firebox is 320 dm. cube holds 50 kg of fuel. Depending on the mode of operation, one device boot provides smooth operation from 31 to 130 hours.

The low level of heat loss is due to the use of inorganic wool as insulating material between the furnace and the body of the equipment.

Teplodar Kupper OK30

Domestic products are ranked fifth. This is due to the relatively low efficiency of 84%. Due to the high power of 39 kW, it is able to heat the liquid to operating temperature in 20 minutes. It is able to effectively heat a house up to 300 square meters. The boiler is designed to work on wood, pellets, coal, and if necessary, it can be used as fuel. natural gas or electricity. All its advantages raise the equipment to a fairly high place.

Advice. Boiler equipped with cast iron heat exchanger, has a high degree of heat transfer and service life, which several times increases its efficiency and reliability.

Boiler rating by price

The cost of heating equipment plays one of the key roles when choosing the required model of a long-burning solid fuel boiler. In each price segment there are the best models that are able to meet almost all consumer requirements:

budget class

Not high price heating equipment does not mean low performance, reliability and lack of stable operation. In this class there are models that are perfect for summer cottages and small private houses:

standard class

How to choose a solid fuel boiler: video

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

To make the right decision and purchase 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 poisoning carbon monoxide in case of leakage.
• Mounting. Gas boilers are installed only by specialists, solid fuel boilers are allowed to be installed independently.
• Cost: Prices for these types of equipment do not vary much, greater value have technical data.

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. 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 correspond specifications 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. Flaws: frequent service(it is necessary to add fuel 4-8 times a day), low efficiency (70-75%), low degree of power adjustment. Such a boiler will good option not for heating big 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. This efficiency is achieved through the built-in electronic automation, turbines, 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; his top part goes through drying. 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 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 already focused on certain area premises. 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 hob included. 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 modern model, which requires only one load of fuel to operate 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: not always technical specifications a cheap boiler may be suitable for a particular situation.

Buying heating equipment is an important and responsible business. There are a lot of offers on the market, but it is impossible to recognize any one model as the best. The choice is determined primarily by those tasks, the implementation of which is important to the consumer.

Which boiler do you like?

Autonomous heating in many ways outperforms centralized heating. It can be turned on and off at your own discretion, adjust the temperature and significantly save on operation. The main thing is to choose the most best way heating - gas or solid fuel.

Features of gas boilers

Models running on "invisible" fuel have two undeniable advantages- take up little space and are very affordable. They are ideal for houses and even apartments where there is no place to store firewood, briquettes or coal. Due to the closed combustion chamber and forced draft, which takes air from the street, there is no need to install the boiler in a separate room. Its small size allows you to hang the unit almost anywhere.

gas boilers have big choice dual models. They not only heat the room, but also provide a home hot water. Such devices are very economical: no need to spend extra money, because the water is heated simultaneously with common system heating.

Solid fuel boilers: pros and cons

As a rule, solid fuel models are chosen by owners of non-gasified houses. The most profitable are the units using wood waste- sawdust and shavings. In addition, many boilers can “consume” different types of fuel at the same time.
Of particular interest are models with additional function stoves. The top surface is made of cast iron. It may have removable rings. During cooking, such solid fuel boilers save electricity or gas.
It is believed that gas models are more practical, since they do not need to be constantly looked after. However, you can choose a machine equipped with a hopper and automatic loading. Ignition, fuel supply and operation circulation pump regulated without human control. Many models can be connected room thermostat and use it to adjust the temperature. With one load of coal, the boiler is able to work up to 24 hours.
By choosing to solid fuel boilers, you should be aware that they have one significant drawback: before installation, it is necessary to equip a special boiler room with a good hood.

Universal combined models

If you can’t decide between the two types of boilers, you can purchase a combined unit. It works well on both gas and wood or coal.
However, it should be understood that the installation of such a boiler will be expensive - at least two to three times more expensive than conventional models. But in the future, such devices are very practical in operation and allow you to save a lot.
Before choosing a specific model, it is necessary to calculate all possible costs: purchase, installation, fuel consumption. For example, gas boilers are much cheaper, but a tie-in to a gas pipeline can cost a considerable amount. On the other hand, building a storage room for coal and firewood can also be problematic. Therefore, only after weighing all the pros and cons, you can provide your home with heat for many years.

Heating boilers combined type have become widespread in the arrangement of private houses. Their main difference from similar equipment is the use of several types of fuel, which contributes to cost savings and independence from the supply of a particular type of fuel.

Combined boilers can combine up to four types: diesel, gas, solid fuel and electric boilers. Such equipment ensures the autonomy and efficiency of the heating system. The transition from the main type of fuel to auxiliary occurs automatically.

Types of combined boilers

Combined boilers are classified depending on the type of fuel used:

1. Gas and solid fuel. The main advantage of such equipment is independence from gas.
2. Gas and liquid fuel. They effectively heat large areas and are easily transferred from one fuel to another (by changing the burner).
3. Gas, electricity and liquid fuels. Suitable for heating private houses. Gas and diesel quickly heat up the room, electricity maintains the set temperature.
4. Gas, solid fuel and liquid fuel. Multifunctional equipment suitable for heating cottages and houses. It is difficult to operate and maintain.
5. Gas, solid fuel, liquid fuel, electricity. Such a system can significantly reduce the cost of heating the room.

Distinctive features of boilers "gas-firewood"

"gas-firewood" belongs to the first type. It is designated by the letters T. G. Solid fuel for it is firewood, coal, briquettes, pellets. The equipment is convenient for those who are just planning to conduct gas to the house in which they already live.

The material for the manufacture of the boiler furnace are steel and cast iron, so the equipment is placed on the floor. Moreover, for a boiler with a cast-iron furnace, strengthen the foundation.

There are single-circuit and double-circuit models of boilers. single circuit can only heat the room, double-circuit additionally provide the house with hot water. Heat exchange units supply 700 liters to housing hot water in an hour.

The combined boiler can have one or two fireboxes. In two-furnace models in the lower furnace is located gas-burner, and a chimney is mounted in the top. Both furnaces heat up at the same time. Combustion products settle on a special pallet. it facilitates the cleaning process equipment. The pallet is installed only if firewood is used.

Advantages of combined gas-firewood boilers

• the equipment has built-in heater and two cameras for combustion of gaseous and solid fuels;
• installation, maintenance and repair do not require special knowledge and financial investments;
• possible connection several heating circuits, that is, at the same time it is possible to heat a house, a garage, a bathhouse, etc., which simplifies the installation scheme of the heating system;
• independence of the mini-boiler house from electricity and gas supply ;
• a small amount of space occupied by the boiler;
• small outlier harmful substances in atmosphere;
• efficiency reaches 90%.

Approximate cost savings, which allows you to get a gas-firewood boiler, is visible from the following table

Criteria for choosing boilers "gas-firewood"

Since one of the energy resources of this type of boiler is gas, its pressure in the network should be taken into account. Boiler performance decreases at low gas pressure. In this case, the possible shortage of power is taken into account.

Next important parameter, according to which the boiler is selected, - its appointment. If the boiler functions only include heating, then you can opt for single-circuit equipment. In the case when it is required to provide housing with hot water, a double-circuit boiler is purchased. This device is of two types: with a built-in boiler or with a built-in coil. The first always has 40-60 liters of hot water at the ready. The second type of device is inferior to the boiler in terms of water volume, but at the same time it has more compact dimensions, weight and saves more fuel. You can always go to a single-circuit boiler connect additionally indirect heating boiler.

When buying a boiler, you must require an official certificate. Without this document, it will be difficult to register heating equipment and obtain permission to connect it to gas supply systems.

Equipment installation

The operation of the gas-firewood boiler involves the delivery and loading of firewood, and loading is done manually. Work of equipment on wood does not exceed four hours.

When buying firewood, their humidity is taken into account, which should not exceed 20%. It is better to buy firewood in a specialized store.

Uninterrupted work heating and hot water is possible thanks to automation. If one type of fuel (solid) is missing, the combi boiler automatically puts the other (gas) into operation.

Thus, the combined gas-firewood boiler is one of the the most affordable types of heating country house. The device is trouble-free in operation, does not require special training in maintenance, safe and environmentally friendly.

The cheapest type of heating a private house is, one of which is firewood. The calmness and comfort in the house will depend on how high-quality and suitable, exactly for your conditions, the boiler you install. Therefore, which solid fuel boiler is better for your home and according to what criteria to choose it, we will understand meticulously and thoroughly.

If you are going to buy a boiler for heating a private house, the first thing you need to know is the area of ​​\u200b\u200bthe heated room. After all, the power of the unit directly depends on this. According to manufacturers, the calculation is simple: every 10 m2 of area requires the production of 1 kW of thermal energy. At total area Houses of 150 m2 have enough power of 15 kW. But everything is not so simple here.

Corrections must be made if:

• The ceiling height is more than 3 m;
• Quantity window openings exceeds the norm;
• The house is not well insulated.

You also need to remember that in harsh climatic zones during the cold season, the boiler will have to be heated constantly, even at night. Therefore, it is better to choose a unit with a power reserve of 5-10 kW, which will allow you to control the intensity of combustion.

In addition to power, the following characteristics are important:

• Productivity or efficiency - important characteristic heating system. This ratio is directly related to design features equipment and method of fuel combustion. For solid fuel boilers, the efficiency is quite high, it is 80-98%.
• Operating cost. The reliability of the brand of boilers depends not only on the manufacturer, but also on the design solutions, materials used for the components and the body, the cost and availability of services, spare parts, and operating conditions.
• The type of fuel consumed is another important characteristic. When calculating the cost of heating in a private house, the price of the selected fuel in the region (coal, pellets, firewood) and the performance of the equipment are taken into account. The more expensive the fuel is and the higher the combustion rate, the more expensive the heating of a private house or cottage becomes.

Kinds

There are several classes of boiler equipment according to the principle of its operation:

Classic.
Quite traditionally arranged. They consist of a combustion chamber and an ash chamber, a tank for a water jacket, a chimney. All known species are used solid fuel- firewood, sawdust, pellets, they can also be heated with coal. They are used in heating circuits with natural air circulation. Every 5-7 hours of operation it is necessary to load the next portion of fuel. The automatic control unit regulates the air supply to control the combustion process of the fuel, depending on the value displayed on the display. temperature regime. In the best models, a draft regulator is built into the chimney, the task of which is to force cold air into the chimney in order to keep the heat inside the furnace as much as possible.

Gas generating or pyrolysis.
These boilers have two combustion chambers. Firewood is placed in the lower firebox, where, under the influence of high temperature and in the complete absence of oxygen, the process of smoldering takes place. Carbon dioxide enters the upper chamber, burns there, the heat exchanger heats up. It is necessary to load fuel once a day. There are models of boilers with automatic and manual draft regulator. Look at user reviews on the forums, think about what is more convenient for you.

Pellet
Why pellet boilers so popular in Europe? It is this equipment that requires minimal human presence and runs on environmentally friendly fuel. Pellets are granules made from sawdust, peat, wood and agricultural waste.

The main advantages of pellet boilers:
• high efficiency;
• wide range of adjustments;
• fuel is undemanding to storage conditions.

Among the shortcomings, we note the high cost of equipment and pellets.
