AnswerHeat pump running cost for a 2-bedroom house
A 2-bedroom house costs roughly £490/year to heat with an air-source heat pump on a standard tariff (about £300 on a dedicated heat-pump tariff), versus around £433/year on gas.
On today's prices a heat pump can cost about the same as gas on a standard tariff — the real savings come from its efficiency plus a heat-pump electricity tariff with cheap off-peak rates.
