I’m probably going to install a Ground Source Heat Pump (GSHP) in a house ~150yrs old with living area of 300m$^2$. Most of the “Fabric First” issues have been addressed (roof, windows etc), though still some some minor work to do; except Internal insulation of external walls.
The walls are about 600m stone with lathe and plaster, with intricate cornices. I don’t want to damage or obscure the cornices, and am willing to accept the penalty.
I’m no electrician but Maximum Demand with diversity is approaching single phase limit with V2G charger and GSHP.
I’m interested if anyone has got experience of similar set up.
