[QUOTE="akaPABLO01, post: 4608824, member: 43748"] If you are using 1kW of electricity for 1kW of heat then an ashp will give you 3.3kW of heat for 1kW of electricity. It is something you should look into. Maybe compliment it with a small solar to help it generate hot water in summer. Loft insulation is very important some 300mm or more to help keep the heat in. To correctly size a pump means a heat loss calculation needs to be done, room by room. Do you have a full wet system radiator in place? A heat loss will determine the size of rads needed also and whether copper pipe runs need upgrading such as 10mm. You say main house, if you have another unit like converted stables or barn you should also consider ground source heat pump on district heating. Gshp is more expensive then ashp to install but gshp will pay you on district heating for 20 years and single unit heated 7 years Rhi. Both system generate heat at a low temperature so sizing rads as well as the heat pump is very, very important and could mean either not enough heat is generated or rads aren’t able to circulate the heat efficiently. You definitely need a heat loss calculation done. [/QUOTE]
