How much does the heater consume and what is the most economical

In the cold season, residents of private homes think about a comfortable temperature in the room. But among many heating equipment it is difficult to choose the best option. Many choose electrical products that have many advantages and consume a small amount of electricity. Consider which heater is the most economical for a private house in terms of electricity.

Which heater is the most energy efficient?

Before the start of the heating season, you should think in advance what equipment will be optimal for the home.

There are several types of heaters:

  • Electric (convector).
  • Infrared.
  • Mycothermal.
  • Air conditioning.
  • Ceramic plate (panel).

Electric heater in the interior

Electric convector

In principle, it looks like an oil cooler. Air circulates through the heating element. Heated air rises, and after cooling is lowered to reheat.

The most popular are models of the company Atlantic. The power of convectors varies from 0.5 to 2.5 kW. To heat the room 20 square meters. m. it will take 4-5 hours.

Infrared heater

Oil and electric products have been replaced by a new type of heating equipment. The power consumption of such equipment is much less. A quartz radiator is a heating element that heats up and gives off heat to nearby objects. Such equipment does not heat the air. It is suitable for quick room heating. But it is not able to qualitatively warm the entire house for a long time.

The infrared device can be installed outdoors. The equipment can be mounted to the ceiling or mounted on legs. For heating rooms up to 20 square meters. m. it will take 2 hours.

Popular models: Eko, Saturn, Beko, etc. The product spends an average of 90 watts per square meter.

Micathermic heater

Such a product is notable for its cost effectiveness and efficiency. It was developed using new technology and has been released not so long ago. The equipment used to be used in astronautics and medical facilities. You can install the equipment on the ceiling or wall.

The mycothermal heater heats up efficiently, as it has several plates that are covered with mica. It is safe as it does not get hot. Items around the appliance heat up evenly.

There is one drawback in the equipment - high cost. A quality model is a product of the company Polaris with a power of 1.8 kW.

Air conditioning

Air conditioning is distinguished by its efficiency. Often used to heat a country house. The equipment consists of an indoor and outdoor unit. Room heating is different from other heating appliances.

Air conditioning works due to the heat pump. It takes warm air into the room using a heat exchanger. Therefore, even at low temperatures, the air heats up and enters the house already warm. Freon is used for heating.Under the influence of pressure, the gas passes in the indoor unit in the heat exchanger and heats up to 80 degrees. After this, freon passes into the outer part and returns to gas under low pressure. After boiling, it re-flows into the indoor unit.

From 2 to 5 kW of electricity is spent per hour, depending on the model. Air conditioners can heat homes even with a large area. Popular models: Samsung, Daikin and LG.

Ceramic panel

Such equipment is also considered economical. The device looks like a ceramic plate. It works on the principle of infrared long-wave radiation. Great for different interiors, as it has a steel heat-conducting duct. You can install the panel on a wall or ceiling.

To calculate the electricity consumption, the dimensions of the device must be taken into account. On average, the panel spends 0.2-2.5 kW per hour. Room 20 sq. m. may fully heat up after 2 hours.

Which heater spends less electricity for summer cottages and other homes?



Based on many experiments, one can distinguish one species that consumes less electricity. Such a device is a convector. The principle of operation is similar to an oil cooler, but differs in its safety and modernity.

Through the heating element, which is arranged in the convector, air circulation occurs. Thus, there is heat transfer. The convector can be left turned on for a long time without supervision, since it is one of the safest devices.

For the country house, such heating equipment is ideal. It does not dry the air, and the heating temperature cannot exceed 60 aboutC. After turning on the convector, the room will start to heat up after 20 minutes. It consumes 25% less electricity than other heaters.

The convector is considered the most economical for the home.

How much does an oil heater consume per day?

This type of heater burns a small amount of oxygen and consumes little electricity. In addition, they are not as flammable as other appliances.

The disadvantages are the high cost and high weight. On average, an oil heater consumes 750W per hour. More powerful heaters spend about 1 kW. But you can find devices with less power.

Since the device works for several hours a day, the energy consumption is much less.

The greater the power of the device, the more electricity it consumes. While the appliance is turned off and in rest mode, it is not wasting energy. Despite some disadvantages, more advantages can be highlighted. That is why it is popular among residents of private homes. You can calculate the amount of electricity consumed after 1 month of using the device.

Calculation of the power of different types of heaters per room area

Heaters are used not only in country houses, but also in apartments. In the fall, when the cold weather starts in the apartment, the heating is still not turned on, so many people purchase electrical products. But in order not to get a big electricity bill, you must first calculate the power and consumption of the device.

For the calculation, the area of ​​the house or apartment and the number of heating appliances should be taken into account. It is necessary to calculate the power of radiators using a special formula.

kWt = 0.277 * c * ϱ * P * h * (t2-t1), where c is the specific heat, ϱ is the density of air, P is the area, h is the height.

As a result, you get the amount of heat that is needed to heat the house and the required power of the appliances.

Power table per floor space

The following points should be taken into account in the formula:

  1. Material and wall thickness. In a house with thick walls, heat loss will be minimal. And with thin walls, the heat goes to the street.
  2. Type of radiators. The batteries may be infrared or oil.
  3. Wall insulation.
  4. The quality and quantity of windows in the house. A large amount of heat leaves through the windows.Therefore, it is important that the windows are of good quality. In this case, the heater can be heated to a low temperature. And if the windows are blown, it is necessary to turn on the device at maximum temperature.

In order to correctly calculate the power of the required heater with all the nuances, you can use the calculator.

Quartz Heater Power

Such equipment consumes a small amount of electricity. The average consumption is 0.5 kW per hour. The type of heater is different from the same oil. In a special stove, a heating element is arranged, which heats up and radiates heat. Heat is distributed evenly throughout the area.

Quartz devices have the following advantages:

  • The heater does not dry the air. Therefore, people in the room will feel comfortable.
  • Beautiful appearance.
  • Long service life.
  • The air in the house remains fresh and clean.
  • The appliance does not heat up to high temperatures. It can heat up to 95aboutC. Therefore, such a product can be considered non-flammable.
  • The equipment accumulates heat for a long time. The appliance heats up and remains warm for a long time. It takes 20 minutes to fully heat the quartz product.

Power of oil heater

Based on the calculations, you can determine the power of the device. But it is worth considering the fact that such heaters distribute heat unevenly.

Around the appliance, the air is very hot, and in the remote parts of the house the air remains cool.

How much energy does an infrared heater consume?

On average, such a heater consumes 0.5 kW per hour. This indicator indicates a high coefficient of performance compared to other heating appliances. If it will work about 10 hours a day, then a month it will cost 150 kW / h. Such electricity consumption can be considered a good indicator.

When buying a heater, you need to pay attention to the power consumption and power of the device. The calculation of power when choosing an infrared heater must be made taking into account the area of ​​the room so as not to overpay for excess electricity consumption.
