> Something like 70% of houses are heated by heat-pumps
To me, living in US Northeast, this is astounding. I've read heat pumps lose efficacy below 25F. My family would never forgive me if I made our house cold. But then I see 70% of the Nordics's house are "warm enough", or dealing colder than room temperature houses.
I've asked half-dozen contractors and HVAC people in my area, and none of them have recommended a heat pump. But, I'm just as suspicious of their motives as I am of the science and environmental populizers on YouTube.
