What are the most expensive and inefficient home heating appliances?

In the winter season, in many apartments, the central heating capacity is not enough, so the owners are purchased with additional devices that allow them to warm in the cold. But at the same time, electricity bills can skyrocket. What are the most expensive heaters?

Fan heaters

In another they are called heat guns, which receives cold air from the room, heats up and is released again into the environment. The cost of the heaters themselves is the lowest on the market. But they have a number of disadvantages: they burn oxygen very much, make noise, are not intended for constant use. Also, heat guns cope poorly with fast heating of the room, so that a room of 20 sq m is filled with warm air, you will have to wait about 5 hours. In this case, the energy consumption per hour reaches about 2 kW.

Air conditioners

Air conditioners can not only cool the incoming air, but also warm it. For this, freon is used with a temperature of 80 degrees, which is heated by internal elements. The room with its help heats up faster after about 2 hours of work, but more energy is spent - from 2 to 5 kW per hour.

Oil heaters

Oil heaters have undoubted advantages - they can work unattended for a long time and give a lot of heat, practically do not burn air. But at the same time, such devices do not distribute warm air evenly throughout the apartment or room, in order to warm a room or apartment, it should work about 7-8 hours. And about 2 kW of energy is spent per hour.

How to calculate daily consumption

It is worth remembering that under a certain quadrature of the room, heaters with different power are needed. This is necessary so that the process of heating the air is the most effective. On average apartment rooms of 16 square meters. m it is worth buying a heater with a capacity of not more than 1.5 kW.

To determine how much electricity will run in a day, you need to know the power of the heater. The higher it is, the greater the consumption will be. It also depends on the mode in which the device operates.

On average, the heater works about 8 hours a day according to the following scheme: heating hour, two hours rest. Having learned how much the device spends kilowatts per hour, it is necessary to multiply this value by the number of working hours. Next, the resulting figure is multiplied by the cost of one kilowatt. It will turn out the amount that the owners pay per day, then it is multiplied by the number of working days of the appliance. The final figure will show how much money is spent on heat.
