The boiler is solid fuel with a water circuit. Solid fuel boilers: characteristics, price

A modern solid fuel boiler of long burning with a water circuit provides the house with heat by burning wood, coal, peat briquettes and other species. Many such products are made of metal, for example, steel or cast iron. It is solid fuel boilers that are the most popular and economical in operation, therefore they are widely used for heating suburban and country houses.

Alternative type of heating

Single- circuit and double-circuit solid fuel boilers are considered to be the most reliable and simple heating method in regions where gasification is completely absent or just planned. In addition, such a system is very cheap. If the customer wishes, any solid fuel boiler with a water circuit can be equipped with a burner, after which the device will be able to operate on the main natural gas. There are models of these units that can work on electricity due to the availability of special equipment.

Types of boilers depending on the material

The most durable are solid fuel boilers with a water circuit made of cast iron that can last at least 20-25 years. Such units are simple in operation and undemanding in care. They work on any fuel, are relatively inexpensive and easily repaired.

No less in demand steel boilers. Most often they are used for heating large areas of 200 square meters. M.

At present, models have appeared, in the production of which two materials have been combined: cast iron and steel. This allowed to significantly expand the capabilities of these units.

Advantages of Solid Fuel Models

A solid fuel boiler with a water circuit, like any similar unit, has certain advantages that make it possible to distinguish it from the background of other devices. We list the main of them:

• This system is an alternative type of heating for rooms where there is no possibility to hold a gas or use electrical appliances.
• Virtually all models are equipped with automation, which provides reliability and safety.
• A long period of perfect operation (an average of 20 years).
• Solid fuel boilers (the price of which is quite acceptable in comparison with other types) can be equipped with a burner, which will allow using gas for the heating system.
• When the unit is running, the fuel burns completely, ensuring maximum efficiency.
• The ecological and economical nature of this type of heating makes it quite popular.

A few words about shortcomings

Solid fuel has some features that are specific to it. For example, in such units it is rather difficult to supply fuel directly to the furnace itself. Boilers for heating the house with a single tab can continuously work no more than 8-10 hours. This means that after loading the fuel, for example, in the evening, by the morning it completely burns out, and the system begins to gradually cool down. The speed of this process depends directly on the quality of the insulation of the room. Such minor inconveniences are easily solved. To do this, it is enough to purchase a compact electric boiler, which is installed together with solid fuel as a support.

Solid fuel boilers

As mentioned above, solid fuel boilers can be single-circuit or double-circuit. The latest models, in addition to the main purpose (home heating), are also able to heat water for domestic needs. The structure of such devices, as a rule, the same type. Each solid fuel boiler with a water circuit is equipped with a special chimney. It is represented by a pipe located in the heat exchanger. It performs the function of heating the water and evacuating the gases after combustion of the fuel. Inside the boiler there are two cylindrical tanks: one is responsible for the supply of hot water, the other for the operation of the heating system. The circulation of heat and water is due to the staple pipes.

A feature of dual-circuit devices is the ability to work on different fuels. That is why many manufacturers order special gas burners for such units. This equipment is displayed on the cost of the product, which is also affected by technical specifications. For example, simple solid fuel boilers - the price of 25 thousand rubles., Equipped with gas burners - from 35 thousand rubles, similar to 4 sections - about 50 thousand rubles.

Mounting Requirements

The installation of a solid fuel boiler must be in accordance with certain rules. For these works it is recommended to use the services of skilled workers. They will not only conduct the installation in accordance with established norms, but will also give a guarantee. However, this does not mean that you need to completely trust the specialists. Therefore, it is recommended to familiarize yourself with the installation features that you need to know when installing a solid fuel boiler with a water circuit.

1. The place where this unit is to be assembled should not be made of combustible materials. Particular attention deserves sex. It is not recommended to install the boiler on a wooden covering. If this issue can not be solved crucially, then it is necessary to build a high-quality incombustible stand.
2. Be sure to install a boiler to maintain a certain distance - 20-25 cm from all surfaces.
3. The pipe joint should be as tight as possible, as this can lead to damage to the device and other unpleasant consequences.
4. The distance of the outlet duct, which is located between the boiler and the chimney, is not recommended to do more than 1 meter.
5. If necessary, you can connect a boiler - the correct installation will not damage the operation of the heating system and will ensure a stable DHW in the room.

Boiler with electric heating element

Solid fuel boilers with a water circuit, which are equipped with electric heating elements, can be automatically adjusted to switch on. As a rule, this is necessary in cases where the temperature of the coolant drops below a preset level, for example, 35 ° C. This means that the unit starts up and starts working, and the main solid fuel boiler remains inactive.
