From the beginning of cold weather many begin to think of how to provide heat in the apartment or the house. One of the most widespread ways of maintenance in the dwelling of optimum temperature is use of various heaters. To exclude unreasonable overexpenditure of energy, it is necessary to calculate the necessary power of the device in advance.

Instruction
1. Determine the area and volume of the room which you need to warm. In the simplest case it is necessary to increase room length by its width, and then by height of walls. Write down or remember the room volume expressed in meters. This size is required at acquisition of the heating device with specific power.
2. Evaluate the room in terms of possible losses of heat. If the room has several windows and doors or is located in angular part of the building, it will be required to buy the heater of a little bigger power. Also demands more significant heating the room located in northern part of the apartment or house.
3. When choosing the specific heater you recognize that for high-quality heating of the room it is required to provide about 1 kW of the energy developed by the heater on 10 sq.m of the room with standard height of ceilings of 2.75 m. If floor-to-ceiling height differs from the specified size, calculate the volume of the room and accept the required power of equal 1 kW on 25 CBM.
4. Review specific example of determination of the required heater power. Let's say you need to provide with heat the room of 25 sq.m which height of walls is 3 m. The volume of the room will be 75 CBM. The room has one wooden window and one door. Having separated room volume into 25, you receive the size of 3 kW. Approximately such power to you will need the heater. If the room northern or angular, add to the found size another 20% of power.
5. Choosing the heater, get model with the built-in temperature regulator. If air temperature outside the house changes, you can change position of the regulator as appropriate. It will allow you to use more flexibly opportunities for heating of the room, changing temperature condition in any given party if necessary.
