In reality to get ASHP insulation right you need to build the walls out and insulate with celotex/kingsman. Cavity wall isn’t good enough.
Someone else covered a point to why they are shit and I would avoid them. I think in reality a combi right now is the only option that works without spending next level money.
It’s also at a point where they are chatting all this shit but the viable options are 5 x the price of the gas equivalent and not great rn

Anyone have solar panels and doesn't think its shit?
I don't see how HW solar saves £37 per year!
Over winter, in northern Scotland, it doesnt contribute much as the days are short and the sun doesn't climb that high. But it can still contribute a bit.
However it's halfway through a fairly cloudy April day and my old serpentine collector is running 12C to 15C hotter than the bottom of the cylinder.
The incoming cold water was 8C this morning and the bottom of the tank is already at 35CIt won't do it all today, but I'll probably be able to completely switch off the immersion again in a month or so. At the new energy prices, that could be saving £2 per day
Just had the EPC from the seller and interestingly it notes that the loft (rated good) and cavity walls (rated average) are already insulated, and 'the assessor did not find any opportunities to save energy by installing insulation in this property'. The windows are double glazed and will be replaced at some point, the floor downstairs is 'assumed' to not be insulated (which we will do'. It's poor performance on the EPC is down to the fact there is no heating installed, and they have some recommendations to boost it (attached - not sure there is a right lot of point in the solar water heating at 108 years to repay itself at the lowest estimate!).
I'm not naive enough to think that this is super accurate, but its better than I thought! I guess getting a professional in may be the way to go, but then I worry they justify their existence/cost by trying to flog you things that aren't strictly necessary.
The section of roof we'd ideally use for PV panels is South, South East facing and we'd add batteries, just need to look at what our energy needs are/might be before I can figure out if we should take the leap.
I'm still worried the ASHP won't be viable without huge radiators, we will heat the kitchen with underfloor but it doesn't look like we'll have the budget/time to do everywhere and I would rather not have mega-radiators everywhere. Hard to get the balance right I guess.
