Please Note - we will not accept the return of heaters after they have been tested, tried or used in any way. We offer a specification service whereby we will help you select the correct heater for your use when you supply the details of the space you wish to heat.

Guidance Notes on Purchasing Heater

In order to find out which heater you need, you will need to know
1) The volume of the space you are heating (cubic meters)
2) The rise in temperature needed (degrees Celsius)
3) How well the room is insulated

Please follow this formula to find what heater will suit your needs

1) Calculate the volume of the space you wish to heat
Volume (cubic meter) = Width (m) x length (m) x height (m)
(E.g. A single garage 3m wide x 5m long x 2.5m high = 37.5 cubic meters

2) Multiply this by the rise in temperature required
(E.g A single garage where a 10 degrees Celsius rise is required 37.5 x 10 = 375)

3) If there is no insulation multiply by 3.5
If there is only light insulation multiply by 2.5
If there is medium insulation multiply by 1.5
If there is high insulation multiply by 0.5

To then get a result in BTU multiply this result by 4

(E.g A single garage with no insulation would mean a calculation of 375 x 3.5 = 1312.50
This then multiplied by 4 is 1312.50 x 4 = 5250 BTU)

If you would like the figure in kilowatts divide the result by 3412 1 watt is the same as 3.4
(E.g. 5250/3412 = 1.5 kW)

Please note these are only approximate figures, we recommend that customers consult a heating engineer before buying large amounts of heating equipment.
