Heating Cost Calculator
Estimate what heating your home really costs.
Consumption = area × W/m² × hours × days / 1000. Multiply by the price per kWh for the season cost.
How it works
Consumption = area × W/m² × hours × days / 1000. Multiply by the price per kWh for the season cost.
Worked example
80 m² × 100 W/m² × 8 h × 120 days = 7,680 kWh. At 0.20, that is 1,536 per season.
Recommendations
- Well-insulated homes need 50–80 W/m², older ones 100+
- Lower the thermostat 1°C to save ~7% on heating
- Insulate the attic first — biggest heat loss
Tips & advice
- Use a programmable thermostat
- Bleed radiators at the start of the season
- Close shutters at night to keep heat in
