May I ask you something? If we assume that is the Area (30m^2) of the outside wall of one room. Then every second we need 1035 Watt to keep the room temperature constant. Then in one hour the required energy of one heater to keep the temperature constant will be 1035 times 3600 seconds which is 3726000 Watts or 3726kW. This is an extremely high number. I would appreciate if you explain me where am i wrong.
