In only a few steps you can calculate your possible savings of heating costs with the heating costs calculator from Solarbayer.
If you already know your annual energy requirement you can enter it manually in the corresponding field.
Please note that the annual energy requirement must be specified in kWh per year.
As conversion factor for heating oil you can use a reference value of 1 ltr per 10 kWh.
Example: a heating oil consumption of 2500 ltrs equates to approx. 25000 kWh.
If you don't know your annual energy requirement it is also possible to calculate an estimated requirement by our tool.
the energy requirement cannot be calculated automatically by this script.
