@Rich44 I have a large house so if your ASHP is 8kwh then maybe a 10kwh+ would be what I need.
There’s only me and the wife so a couple of showers each day is about all the hot water I use from the combi.
The only person who got all his work done by Friday was Robinson Crusoe.
Anything i post over three lines long please assume it is an article lol.
