As you know, in our country, gas is the cheapest fuel available for use in the heating systems of buildings and structures. Despite this, many of our compatriots choose heating schemes (CO), in which electricity acts as an energy carrier.
The types of home heating with electricity will be discussed in this publication.
Types of electric heating
Today, our compatriots have access to five options for heating their own homes with electricity that are different in design, principle of operation and efficiency.
- Water system using an electric boiler.
- With electric convectors.
- Heating the house with fan heaters.
- Using IR panels.
- Application of the “electric floor heating” system.
Next, consider each type of electric CO in more detail.
Electric heating boiler systems
The principle of operation of electric heating water heaters is based on the transfer of thermal energy to a heat carrier, which gives off the accumulated heat to the air in the room. Today, on the European market of climate technology there are three types of electric boilers operating in water heating systems at home.
- Boilers with heating elements (heating elements).
- Electrode hot water devices.
- Induction installations.
TEN electric heating boilers are the most in demand among the European consumer. The principle of operation of this equipment is simple: the heater heats the moving coolant, which, in turn, heats the batteries. The circulation of the coolant along the circuit is provided by a circulation pump, which can be a separate element or part of the design of the boiler plant. The power of such boilers varies from 3 to 50 kW.
The main advantage of this design is that the coolant does not directly contact with electricity, which eliminates the risk of high voltage damage to the owner. The disadvantage is the limited resource of the heating elements.
The principle of operation of electrode boilers is as follows: a constant electric current flows through the installed electrodes. The coolant (water, and most often brine) is not a dielectric and conducts current well, as a result of which it is heated.
The main advantages are reliability and small dimensions. Disadvantages — high requirements for the coolant.
The principle of operation of induction-type heating installations is as follows: the boiler heat exchanger (through which the coolant moves) is heated under the influence of a powerful magnetic field. When the heat exchanger is heated, thermal energy is transferred to the heat carrier.
Advantages: reliability, practically no scale is formed, high degree of safety. Disadvantages: significant dimensions, weight and installation cost.
Important! Before installing a large capacity electric boiler, consult a qualified electrician about the wiring in your home.
Heating the house with electric convectors
Electric convectors for home heating are wall-mounted or floor-mounted devices in which air is heated by an electric heating element enclosed in a ceramic case.
The air is heated by a heating element located at the bottom of the device. Rising the upper part of the device, heated air gives way to colder air. This is how the air circulates, heating the room. Most models have a built-in thermostat to regulate and maintain the most comfortable air heating temperature. These products are made of steel or aluminum and have the appearance of modern heating radiators.
The main advantages of heating a house with electric convectors: installation in any place convenient for this; with correctly calculated power, the room warms up quickly enough and without human intervention. Cons: relatively low power of one convector, which varies from 0.5 to 3 kW.
There is an opinion that the heating of premises with IR radiation is the most economical and as close as possible to natural. The principle of operation of these devices is that IR rays do not heat the air in a heated room, but objects that are located in the area of the emitter. In this case, all surfaces in the room are already heat exchangers that give off their heat to the air.
IR heaters are ceiling and (rarely) wall-mounted. These devices have many advantages:
- Oxygen is not burned during operation.
- There are no installation problems.
- These devices do not circulate air and do not understand dust.
- Service life more than 30 years.
- Economical and fireproof.
The only disadvantages of heating a house with IR emitters are the rather high inertia and the relatively high cost of the panels.
Important! Most often, infrared heaters are used to heat country houses and small buildings.
Structurally, the “electric floor heating” system is made of heating elements laid under the floor covering (linoleum, laminate) or concrete screed, which can be cable or film. As a result of the work, the floor is heated and, as a result, the air in the room. Connection to the household power supply is made through a current regulator, thanks to which you can set the required degree of heating in a heated room.
Advantages: uniform distribution and heating of the room. The disadvantage is the complexity of installation.
In addition to the considered electric COs, various types of fan heaters are quite popular for heating small rooms. Their advantages: mobility and fast heating of a heated room. Disadvantages: high wiring requirements, fire hazard and uneconomical.
Advice! If you decide to create an electric CO in your home, then before deciding on the use of one or another option, carefully weigh all the advantages and disadvantages of each and be sure to consult with a specialist.
