Learn how the calculator works

1

Select your zone

In which zone do you live? The country is divided into three areas according to the average daily minimum outdoor air temperature.

2

Select the age
of your home

This will determine insulation levels. If your home insulation has been upgraded or double glazing has been retrofitted, choose the next category up.

3

Select the size of
your heating space

Be realistic when choosing this size. Match the area to the space you are trying to heat, and bear in mind these calculations are based on a ceiling height of 2.4m.
