Since there are many different types of heat pumps and control systems, we use a simplified rule of thumb to help estimate your electricity consumption realistically.
We calculate with 45 kWh per m² of living space – this is slightly above the average (typical range: 27–42 kWh/m²) and thus provides a safe guideline.
Formula for consumption estimation:
Estimated annual consumption (kWh) = 45 × living space (in m²)
Example calculation:
You have a living space of 120 m²:
➡️ 45 × 120 = 5,400 kWh per year
This estimate is only a rough guideline. Actual consumption can vary depending on the type of heat pump, insulation standard, and heating habits.
