I’ve just had a heatpump installed just a 3 bed detached house 1950s normal insulation (loft old double glazing and cavity.) Cost was £4000 after the grant. 8kw heatpump (Dailkn) including 3 bigger radiators. Fitted by Octopus and very pleased with their service. Cost of running it over the year will be about the same as gas - maybe a bit less as i have an ‘EV tariff’ so my electricity costs per kwh are very very low. (And my car fuel costs are also 10% of what they used to be!) Decided to get solar panels afterwards and it’s great. House has a EPC Grade A now. 6 years ago it ran on coal! And I sold my 5 year old gas boiler for £350 on ebay.
The 350% efficiency is because the heatpump is pumping existing heat from outside - it steals heat from the air on your street basically - and squeezes it into the small space of your house. It doesn’t ‘make’ heat - just moves it and squeezes it down a bit. Only need about 0.3kwh of electricity to get 1 kWh of heat into the house. Sneaky. (A gas boiler actually has to make make heat by burning gas, and a bunch of that heat disperses out of the flue so it can’t even reach 100% efficiency).

In Scotland there is a £9,000 grant for heat pumps if your house isn’t near the gas grid.

@@constructioneerful so does it make the air on the street colder?
