Main characteristics
A boiler is a device that generates thermal energy by burning gas. It is used for heating private houses, apartments, less often utility rooms, warehouses, industrial workshops. The process of connecting a heater to distribution circuits is called piping.
The choice comes down to determining the main technical characteristics. Take into account performance, installation method, dimensions. You need to pay attention to the reviews of experienced users. An undoubted advantage of any heater will be the official manufacturer's warranty.
Mounting type
When buying, this is the main criterion. The model is selected taking into account the dimensions, so that it does not take up much space indoors.
By type of installation are:
- Wall. Suspended heater with compact dimensions. This has a negative impact on performance. It rarely exceeds 35 kW. Wall-mounted boilers are recommended for apartments or houses with an area of less than 100 square meters. m.
- Floor. Heavy and overall unit for houses, apartments with an area of 100 sq. m. Floor products are installed in a separate room - a mini-boiler room.
Wall-mounted boilers are cheaper. The kit is usually supplied with circulation pumps, auxiliary equipment, spare parts. Floor heaters are more expensive and are supplied without additional equipment.
Number of circuits
The principle of operation of the heaters is based on the heating of running water due to the combustion of gas. Fuel enters the plant from the main gas pipeline. The hot liquid is pumped into the circuit and transferred to the heating radiators installed in the rooms. A similar principle applies to hot water supply. The availability of such a function depends on the number of circuits.
Heater types:
- Single-circuit. Hot water circulates only to supply the radiators. Heaters are used for space heating, but are not connected to the water supply pipeline.
- Double-circuit. They heat the liquid for both heating and hot water supply.
Single-circuit models can be used simultaneously for the heating network and for hot water supply at home. To do this, they are equipped with a storage boiler.
Principle of operation
The standard mechanism of operation of a single or double-circuit heater has been declared obsolete. The new models have an improved heating principle.
The principle of operation affects the efficiency of the device.Efficiency reflects the ratio of heat produced to energy expended. The higher this figure, the better
According to the principles of work are:
- Convection. A standard appliance in which water is heated by gas combustion. Combustion products, together with residual heat, are removed through ventilation.
- Condensing. It has an auxiliary heat exchanger that uses condensate produced by burning gas and heating water. Condensing models use less energy for higher performance and require fewer repairs.
The disadvantage of condensation models is the price. Improved boilers are much more expensive than convection ones.
Combustion chamber type
For efficient operation, access to clean air and the removal of combustion products are required. These functions are influenced by the type of combustion chamber of the boiler.
Camera types:
- Open camera. The air is taken from the room where the unit is installed. Combustion products are discharged through forced ventilation into an equipped chimney. Heaters with an open chamber are called chimney.
- Closed chamber. Connected by a coaxial channel, which leads to the street. From there, air enters the chamber, supporting the combustion of gas. Heaters with a closed chamber are called turbine.
On the modern market, the assortment includes heaters equipped with a built-in hood that accelerates the removal of combustion products from the chamber. Usually these are wall-mounted heaters that are mounted in the kitchen or in the bathroom. They are recommended for apartments and cottages where it is impossible to equip an individual chimney.
Power calculation
In this matter, it all depends on the area and volume of the room. The optimal indicator is 1 kW per 10 squares when operating in normal mode. Sometimes the device works more intensively, which requires additional power reserve. Therefore, the indicator should be 20-25% higher.
When calculating, the method of supplying oxygen to the combustion chamber and removing exhaust gases is taken into account. For systems with forced circulation, the operating pressure in the installation is from 1.5 to 2.5 mbar. For buildings with 2 or more floors, the appropriate nominal pressure is determined individually.
Floor installations with forced fuel supply reaches 7-10 bar. They are used for heating apartment buildings and industrial buildings.
Some people think that it is better to buy the most powerful boiler. But they cannot be used in small rooms, since fuel consumption will be higher, the burning time will increase. Another reason is the low quality of main gas.
Energy dependence
Heaters are divided into volatile and non-volatile. The first category includes equipment that operates only in the presence of electricity. If there is no power supply, the device turns off - the electronics cannot work without power.
The disadvantage of volatile gas boilers is that they are sensitive to network outages. Protective mechanisms are built into the design to prevent damage due to power surges.
Non-volatile boilers are equipped with a flexible configuration system. In case of emergencies, the device can work without being connected to the network. The electric carrier is heated by gas, but electric ignition does not work. These devices are recommended to buy for residents of regions with frequent power outages.
