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'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.

eh? Did you write it? Didn't get my click, tired of bait articles.

Thats true, and tech journalists absolutely love it with no thought to viability or if they are being sold snake oil

The only issue with renewables is they need grid storage (possible) and back up from other power sources (nuclear) and it does not solve the issue of heat, generating heat with electricity is expensive, industry in particular but people too tend to like cheap heat.

Unfortunately the holy grail for battery technology is like nuclear fusion, it has been promised 6 times a year every year.

Data science is fine if he likes it, hell if he does not and he will go nowhere.
