How do I know what size of system I require ?

This task is more accurately carried out by one of our qualified engineers, however there are 'rule of thumb' guides to calculating heat-loads in residential applications.

If no excessive solar gain into the room exists, and there is no heat output from electrical equipment, take the floor area of the room in square metres and multiply it by 100 watts. i.e. (4m x 5m) = 20 sq m x 100 watts = 2000 watts or 2 kilowatts.

If the room is within an attic space, has sizeable south-facing windows or contains a substantial amount of heat-generating electrical equipment, then these additional heat-loads must also be considered, increasing the factor up to anything around 200 watts per square metre.

i.e. (4m x 5m) = 20 sq m x 200 watts = 4000 watts or 4 kilowatts.

Many other factors are considered by our engineers during a survey visit, in order to correctly assess your requirements. So please allow us here at Apollo Air to provide you with a free, no obligation, consultation.
