The number and type of heaters required depends on the following:  size of the room, insulation, size and type of windows and window frames, orientation in respect of the sun, prevailing climatic conditions in your area, use of the room, ventilation requirements and the thermal comfort level you require.

If you have average requirements, you can cover about 60-75% of your floor with the Coldbuster heating system, however, in a bathroom, all tiles where people may walk should be heated, which normally means 90% of the available floor area.  Contact us for an estimate of your heating requirements or consult the colour coded guide underneath.
