Gas absorption heat pumps are usually installed outside, and gas and supply pipes are connected from inside to outside
underground and sealed. The good news is that current methods of heat distribution inside the house – such as your pre-existing radiators – do not have to be changed, and there is no upheaval from the installation side of things. Indeed, in most cases, you can continue to use your existing radiators, water tanks etc.
What’s more, thanks to the limited use of electricity in a GAHP unit, there’s no upgrade needed on your home’s electrical switch cabinet. Of course, any flue gas and condensate must to be discharged according to legislation, but that’s a regular job for installers.
