m²

W/m² values are simplified reference heating powers, not measured average consumption. Outdoor conditions and actual heat losses are not modelled. This is not a heat-loss survey.

%

The illustrative 50% load factor represents the average proportion of reference heat output during the selected hours. Adjust it to your situation; it is not measured.

📊 Cost per heating season

All three systems supply the same useful heat.

💡 Why are costs different?

The load factor is an assumption, not a measurement. Resistive heating converts around 1 kWh of electricity into 1 kWh of heat. Heat pumps can deliver multiple kWh of heat per kWh of electricity. Pellet stove efficiency also matters.
