50 watts per square metre

If I want to use infrared heaters to heat a room, how many watts do we need to heat that room?

The answer is in the title - 50 watts per square metre!

Of course this assumes that you have a standard height of ceiling (around 2.4 metres), that the room doesn't have too many windows or glass doors to the outside, and that the room/building is insulated to modern standards.

If you have an old house, or if you french doors to the outside, or if it is overly draughty, or if you have very high ceilings, you may well need to use 80 watts per square metre or even more.

50 watts per square metre of floor space!

Assuming that your property (residential or commercial) has been insulated to current modern standards then you will need around 50 watts per square metre of floor space to keep your room/property heated using infrared heating panels!

So, for a room about 12 square metres you need just 600 watts of power to keep the room warm!

All of the energy from the panel needs to come down into the room for this calculation to work, so sticking the panel on a wall will require a bit more power (yes, fit it on the ceiling to get maximum efficiency), got a lot of windows, you may also need more power (infrared will go through glass), always keep the door/window open letting in cold air, you might want to think about having a bit more power!
