Heat Pump Calculator — How much would you save?
Compare what you pay for heating today (oil, gas, pellets, air conditioners) with a heat pump, based on the climate zone of your area. Four fields, instant result.
Got a roof? Try the Solar PV Calculator too — a heat pump plus solar is the cheapest way to heat a home — and see how your energy class climbs with the Energy Class Upgrade tool.
Frequently asked questions
How accurate is the calculation?
We use indicative consumption benchmarks per construction period and climate zone — not a full energy study. It is an honest first estimate; precise sizing happens during the site survey.
Is a heat pump worth it compared with oil?
In most oil-heated homes the savings exceed 50% of the annual heating bill, thanks to the seasonal performance factor (SPF ~3.5) of the heat pump.
Is it covered by Exoikonomo?
Yes — replacing the heating system with a heat pump is an eligible expense under Exoikonomo (the national home-energy subsidy). The percentage depends on income criteria; we handle the whole application.
Does a heat pump work with my existing radiators?
Often yes, with a high-temperature heat pump or minor adjustments. During the site survey we check the pipework and propose the right solution.
