ScotT as it’s a hybrid system I am looking to install there is no need for a heat loss survey as the combi boiler kicks in if the Hybrid ASHP can’t cope when temperatures are really low.
I am looking to install a reasonably large hybrid ASHP at 9kw, I don’t think you can go much larger with a hybrid, which will cover most days except the really cold ones.
The only person who got all his work done by Friday was Robinson Crusoe.
