The running costs of an air source heat pump

[@jezzaandrews1940]

Hi, interested where you got the average SCOP from? Cheers

That's from the MCS, so set a lot of the standards for low carbon products.

Does this calculation work if you live in a colder area of the country?

[@WeLoveHeatPumps]

@@rasmusanker2999 yes. You just need to reference the HDD for your area. This info is available on the met office website

HDD x Heat loss x 24 you have forgotten to calculate for hours your calculation gives you kWdays per year

@@allisternoble8349 that would be the case if we were using the traditional heat loss calculation method. This is a short cut cheat method where we don’t need to multiply by 24. We would always recommend a full heat loss calculation method if you are considering installing a heat pump. This method is more to get a general idea of your likely running costs
