Most electric space heaters have a power requirement of single phase models: 3 kW, 5kW(max), where any electric heater over 6kW requiring a three phase 415V electrical supply. With mains gas a heating requirement for a building of 30kW is not a problem, but for a electric heater that would be 125A which can take a huge chunk of a commercial buildings electric energy supply incomer of 100A per phase. This is why many commercial buildings with limited electricity supplies use air heat pumps such as air conditioning and gas. For a spot heating large areas, direct electric heating such as fan heaters and oil filled radiators can be un-economical use of power but are useful for localized heating.
How Much Space Heating Power Is Required For My Area
Another Example: An area(A) of 250 m3 requires (A)250x33(W)= 8.25 Kw (x 3412= 28000 Btu)
