What does a heat pump cost to run per year?

A heat pump in a typical single family home uses 3,500 to 5,000 kWh of electricity a year.1 With a heat pump tariff of around 28 cents per kWh that is about €980 to €1,400 a year.2

Older houses without floor heating sit at the upper end, because the pump has to heat the water more.1,3 Your quote assumes 4,200 kWh a year.4 The exact value depends on the winter and on how much hot water you use.
