They designed for a very high flow temp (45deg) which would deliver a horribly inefficient COP.
I guess they have skin in the selling energy game.
This also meant they could underspec the radiators / change fewer of them.
In addition to the above, I had the following issues:
- 1 month delay when they refused to believe my AC unit wasn't defined as a heat pump for planning permission. The local planning officer I spoke to described their POV as aggressively unnecessary
- 1 month before install, I got an email saying they were swapping out the specced hot water cylinder for a much cheaper, less efficient one (about 20% less efficient). As it was a fixed price quote, they were not changing the cost to me. All margin for them.
- The final straw was when they said three weeks before install that they'd need to go through another home visit and potentially go through planning because the surveyor put the heat pump in the wrong place on their drawing despite being incredibly clear where it would go from the start.
The person who dealt with my install throughout was incompetent, slow to respond and impossible to get on the phone.

Soul-
Thanks for this. My dealings with them so far have been good but will keep this in mind.
How did you get a view on what you thought the right flow temperature? Presumably this meant you weren’t happy with the radiator upgrades they were suggesting. Just did the heat geek quote as comparison and they are quoting a lot more.
We don’t need planning permission so that side is simpler for us.

Any details on what was shit about the design?
Did you go with another provider or not yet?
