TO DETERMINE THE SIZE OF HEATER REQUIRED FOR A GIVEN AREA USE THIS CALCULATION.
Determine area in cubic metres L x W x H in metres (A)
What temperature rise is required in °C? (T)
How well insulated is the building?
Good
= 1.2(K)
Heat requirement (btu/hr) = A x T x K x 4, to get the answer in kw divide by 3412.
e.g. a badly insulated enclosed area of 2000m³ requiring a temperature rise of 10°C will be:
2000 x 10 x 3 x 4 = 240,000 btu/hr or 70kw/hr
Large areas may require multiple heaters.
