There is a group of varieties of such heating devices. Boilers are classified according to the installation method and the nature of the fuel.
Gas boilers
Blue fuel heating appliances. At the moment, gas equipment can rightly be called the most common type of heating equipment - approximately 7/10 of the total number of devices are operated, which is due to the low cost of blue fuel and the extensive gasification of the Russian state. These heating devices are divided into 2 subspecies:
- Wall mounted. They are equipped with an expansion tank and a circulation pump, which significantly saves the occupied space in the room where such boilers are located. This subspecies is classified into two groups. With two circuits - provide heating and increase the temperature of hot H2O. These devices will be very useful for residential premises in the private sector due to their small size, ease of installation and diagnostics. With one circuit - they function only in the heating circuit for glowing the coolant.
- Floor standing. They are required in accordance with safety requirements in a specially equipped room with all the rules and conditions put forward by gas institutions. They operate on the basis of a heat exchanger made of cast iron or steel. Floor heaters are divided into equipment with atmospheric and inflatable burners. The latter are quite easy to operate, less expensive, and the operation of the devices does not create a loud buzz. Atmospheric burner boilers are more efficient and more expensive. Devices with inflatable burners have a significant advantage - methods of installing burners that operate both on blue fuel and diesel fuel.
Diesel boilers
Diesel heating equipment. Their main feature is a replaceable burner. By changing the burner, it is possible to replace the type of fuel used in this device. The device for heating on a diesel engine has an uninsulated combustion compartment, operates on 1 heating circuit and is manufactured exclusively in the floor.
Solid fuel boilers
Solid fuel heating equipment. The oldest and most common type of heating appliances among Russians. Such boilers are used to provide heat in the room and to increase the water temperature to a high value in cottages and industrial enterprises. This type of equipment is used in structures located at a great distance from the city limits. Such devices operate independently and are completely independent of the presence / absence of electric current.
Electric boilers
They do not need special approval and approval for functioning in the residential sector of the private sector. The main specific feature of such devices was the integrated equipment of systems and tuners to. Electric boilers are used as a fallback for equipment operating on solid fuel if the wood has already been burned. These boilers are comfortable in a small heating area, where it is impossible to mount a solid fuel heating device with a large combustion compartment, as well as in areas where gasification has not reached.
Combined Fuel Devices
The main characteristic feature of universal equipment for heating is the ability to use immediately a group of types of fuel. The basis of the operation of such an aggregate is solid fuel, and other types (electric current, blue fuel, diesel) are used as additional ones. This specific feature makes it possible to operate the device in various regions in a variety of settings. The most modest set of a combined boiler consists of a water jacket, a combustion chamber and a frame. In addition, at the request of the manufacturer, a pump, automatic systems, thermostat and protection structures can be attached. The burner is usually bought separately. The frame of the device is cast iron or steel. The latter fail less often, and the former have a large mass.
Varieties of combined heating devices are: devices with a compartment for burning solid fuel with the additional installation of mounted burners on diesel and light blue fuel; devices with replaceable burners for blue fuel and diesel engine with an integrated electric glow element; wood-gas generating (wood-gas) devices.
How to correctly choose a heating device for domestic use
The selection of the boiler must be carried out with an eye to the following parameters: cost, type of fuel, power, method of getting rid of exhaust gaseous substances, installation, number of circuits. In terms of cost, equipment is divided into 3 main categories: efficient and expensive (usually these are brands created in Germany and Sweden); average in cost, but worse in efficiency (South Korean, Italian, Spanish, Japanese, Slovak, Czech models). The power is calculated based on the meter of the heated area and possible heat loss. As for the number of circuits, then for ordinary heating it will be enough for a 1-circuit device, and if you also need to heat water, then it is better to buy a device with 2 circuits.
