In England a figure of 25 Watts per m3 is usually used for this calculation. We prefer to use a figure of 30 Watts assumed for Scotland to allow for climatic variations!. If a very well insulated property 25 watts should be ok even in Scotland.
Above assume reasonable levels insulation in walls and roof
Room Length (m) x Room width(m) x Room Height (m) = m3
m3 x Watts per m3 = Power requirement
e.g. Living Room 3.6m x 4.5m x 2.4m =38.88m3
38.88m3 x 30 Watts per m3 = 1166watts
Total infrared panels wattage for room should add up to the above figure (or more)

Available Heater sizes Max room volume ( based 30 Watts per m3)
IF IN DOUBT GO OVER! MORE POWER THAN REQUIRED WILL
JUST CAUSE HEATER TO HEAT QUICKER AND CUT OUT QUICKER!
It is important to ensure you have the right size of heater for your room. If you under power a room this can lead to inefficiency,feeling cold and increased costs, as the heater tries to get the room up to the required temperature but can't, so the heater stays on all the time. If in doubt it is always better to have a little too much power as all that will happen is the room heats up quicker and cuts out quicker.
The information opposite should enable you to accurately assess your needs, but if you are in any doubt please get in touch and we will be pleased to help out.
