I've worked construction, I've worked around a massive redvelopment involving ASHP and the problems that estate is having is legion. They really don't work as well as they hoped though I am pleased for you that you are having a good experience.

But 1000+ cases does not replicate your positive experience and the costs of installation (naturally inflated by being council of course) were very high because you need bigger radiators and a lot more insulation due to them running 10 degrees cooler.

I mean you can also pair them with an HVAC system instead of relying on central heating, but that also comes with it's own installation problems. Roughly how long ago was this construction project, if you don't mind me asking? Heat pump technology has developed very quickly in the last decade.

Lastly I just want to share a short article about the heat pump market. Over 30% sales increase in Europe is absolutely massive, and that's with supply chain issues in the mix.

2022 mate where are you from because ASHP work very different efficiencies depending on ambient temperatures. I'm in the UK and for various reasons our temperature variation is truly bad for its efficiency.

I'm from Portugal and have very mild winters, which is a blessing. But heat pump sales are also rocketing in places like Norway and Iceland. A lot of sales in these countries are from ground source, but ASHP are also on the rise there.
