I always thought heat pumps were expensive waste of time

Nice Dylan Thomas reference there!

Dylan Thomas had problems with double vision totally related to alcohol consumption. now pirate is suffering similar symptoms: double posting. put that neat rum down. ??

put that neat rum down

Ok, put it down the hatch, what now? Another one down? oh yeh!

It's enough to turn a man to drink (any old excuse) this nonsense. Those government grants, they aren't from the government they're from us the people held to ransom through our energy bills and taxes. Shhhh, don't tell anyone, not a lot of people know that. Instead they get a warm glow (which might be an interesting and more realistic energy strategy) thinking how kind the government are giving us grants. Think I am being cynical, your'e right.

ASHPs aren't the best solution for every house but that doesn't mean they don't have their place. Here in the north of Scotland there aren't many places outside of Inverness that have mains gas.

The video is correct in that they are not suitable for many older houses but in new builds they can work well, especially when paired with UFH. In small houses the air-to-air units can even work quite well.

? ? ? ? ?
"Can" being the operative word.
Yes, if the house builder builds something well insulated, puts UFH in (especially in the otherwise cold block of concrete they tend to have as a ground floor), then a heat pump will probably work well. But as long as they carry on with the attitude of "doing it this way will save us 2d, so we'll do it this way" then we'll carry on getting new houses where HPs aren't going to work well.
They aren't going to fit UFH because it costs more than fitting a rad. They aren't going to fit an oversized rad because fitting the minimum size the figures suggest might work is cheaper. They aren't going to fit passivhaus standard insulation because that costs more than fitting the minimum the BRs (building regs) allow them to get away with - if they even fit it (c.f. a program on TV a few years ago where a big name housebuilder didn't even fit the roof insulation, it was still in rolls in the attic, and they had to take roofs off to fit it).
The quickest and simplest win for new builds would be to simply tighten up the BRs to need better thermal performance - then new builds would become better performing.

In fact in the new build we just completed, we came in a few days in after completion and there was a massive amount of water leaked. It turns out it was from condensation from above the insulation. It then transpired the "architect" got it wrong in the method of installing it. Cue, major work. I mean if you can't even get that right in a new build.......what hope?
