Heating cost savings calculator
Estimate how much a more efficient heat generator saves per year.
Savings per year
€441
- Savings (kWh/year)
- 3,673
- Previous cost/year
- €2,400
01
Via efficiency
The saving comes from the ratio of efficiencies: 1 − η_old/η_new.
02
In kWh and euros
The saved share of energy and the energy price give the annual saving.
03
Just an estimate
Use, climate and real efficiencies vary — the figure is guidance, not a guarantee.
Rough estimate, no warranty; real savings depend on use, climate and the actual efficiency.
