Starting out on my heat pump journey

[Ronski]

My house, which is mostly 1970s and around 170 square meters, has a heat loss of just under 7 kW, so I would think a 100 year old 370m2 house would likely need more than 8.5kW.

Maybe, maybe not! He says the insulation has been thoroughly upgraded. If the insulation has been upgraded to a high standard then 8.5kW is genuinely realistic. Particularly if (as I say) there is secondary heating for the coldest conditions.

Considering my insulation has been upgraded, I have cavity wall insulation as well, my house is roughly half the size of his, I think it's pretty conclusive he'll have more than a 8.5 kW heat loss. Yes, if there is sufficient secondary heating then he may well get away with an 8.5 kW heat pump, BUT I have secondary heating, a 5kW WBS, but the heat gets trapped in the lounge dinning room, and doesn't really heat the rest of the house even with the doors wide open.

We'll find out when he gets the heat loss survey done.

March was an incredible month for solar, we generated 1357 kWh, we exported 1649 kWh and imported 1123, mostly at 7p kWh.

Today we generated 65.58 kWh, currently at 59.5 kWh exported, may even break my record of 70 kWh exported.
