Very often in residential premises there is an infrared heater (IR device). People prefer this type of heaters because they are convenient to use and beneficial when heating a room. With such equipment, it is not only comfortable, but also economical. The device operates on the principle of heat transfer from the point of radiation of high temperatures to bodies with low temperature using infrared waves. In this case, rapid heating of the surface occurs.
How much electricity does an infrared heater consume
After the objects gain their temperature, they return 30% of the heat to unheated air, while at the same time keeping the flow of electrical energy to a minimum.
IR equipment spreads its electromagnetic rays to the surface of the interior of the room. In parallel, the room is heated from the surface of the walls and household items. IR heater works on the principle of penetration of sunlight.
Advice! The infrared heater should be pointed at the interior. This will help to save heat and not let it out. It is not recommended to direct it at doors and windows.
Several factors affect the consumption of electrical energy:
- how many square meters are the premises;
- consumer power IR device;
- heat loss coefficient.
Choosing IR equipment should be guided by the following factors:
- consumer capacity;
- what is the consumption of electrical energy;
- temperature limit of heating of a tungsten spiral;
- limiting temperature of incandescent material around the spiral.
Experts recommend purchasing devices that reach a border of 7000WITH.
Infrared heaters are of two types: short-wave and long-wave. You can distinguish between them with the naked eye. Short-wave devices in the dark emit waves that a person sees. Accordingly, long-wave radiation cannot be seen.
Benefits of IR Devices
Among all heating systems, the leading place is occupied by infrared devices for saving electric energy. Advantages of IR devices:
- they do not burn oxygen in the air;
- they heat large rooms, can be used in restaurants, cafes and shops;
- the heating rate of the room is several times greater in contrast to other devices;
- uniform distribution of heat throughout the room from bottom to top;
- It does not pose a danger to the human body (colds are treated under infrared rays);
- a regulator is built into it, which allows it to automatically turn on and off;
- positive effect on the body;
- makes no sounds;
- does not dry air and does not drive dust;
- in winter works great in outer space;
- fireproof;
- Do not interfere with the operation of other ventilation devices;
- easy installation work;
- aesthetic
- long-life device.
How to determine the power
Everyone is interested in the question of how to determine the power? When purchasing an infrared device, you should additionally purchase a thermostat. But more expensive models of the device are already equipped with them. Using a temperature controller, you can control the temperature, thereby saving electrical energy. Heat is supplied in a point-like manner, which allows heating both houses and apartments, as well as outdoor areas.
Shortwave IR Devices
The most popular models of short-wave heaters are incandescent lamps and gas emitters. All items that are close to heaters are heated. A person can see infrared radiation precisely because the surrounding material absorbs electromagnetic waves.
A tungsten spiral is used as a heating element. Tungsten burns at a temperature of 33500C. Range of short-wave infrared device 200-7000WITH.
Example of calculating the energy consumption of a heater for a month
As an example, a short-wave device with a power consumption of 0.5 kW / h is taken. With such an indicator, the efficiency (efficiency) will be high in relation to other similar heaters.
The appliance will be turned on for approximately 10 hours a day. After making calculations for the month, we can say that the device will take 150 kW / h. For an infrared device, this is a relatively small indicator of energy consumption.
Important! When purchasing the device, it is necessary to take into account the area that it will heat. Do not take a device with high power for a small room, as this will entail extra costs for paying for electricity.
Comparison of power consumption with other types of heaters
As an example, take a long-wave device, which is in demand. The power of IR equipment is approximately 1.5 kW. The calculation of energy consumption will be carried out under the following conditions:
- The room has 15 square meters.
- Outdoor temperature -200WITH.
- Desired room temperature +200WITH.
In the last place will be placed fan heaters. They have low efficiency and consume about 2.5 kW / h.
Oil coolers will be less wasteful. They consume about 1-2 kW / h, but they heat up very slowly.
With relatively low power consumption, convection devices (convectors) come. They consume about 1-1.5 kW / h.
