Select location of your project
Do you want to conduct the calculation for a new building or an existing building?
Select your current water-borne system
Enter actual need.

You've chosen NEW BUILDING. Remember that the building's demand for energy must be provided regardless of heating system (eg heat pump). This means that you have to specify the actual need and not planned purchase of energy.

Enter the buildings annual requirement for room heating incl. ventilation:
DKK/year kWh/year
Enter your annual requirement for domestic hot water:
DKK/year kWh/year
Enter your annual energy costs or energy consumption

You’ve chosen EXISTING building. Tick for your current source of energy. Then you’ll have the opportunity either to provide your energy cost (DKK) or your energy consumption (kWh). You can also choose a mix of two or more sources of energy.

If you provide electricity as source of energy the system automatically withdraw 5.000 kWh from your energy consumption. This energy is included in the remaining household electricity..

Sample: If you provide 30.000 kWh as your annual energy consumption, 5.000 kWh automatically withdraws, which implies an energy consumption of 25.000 kWh for heating and hot water.
