Matt Simon on Wired.com:
If heat pumps don’t actually work in frigid weather, no one told the Nordic nations, which endure Europe’s coldest climates, with average winter temperatures around 0 degrees Celsius (32 degrees F). As of 2021, Norway had heat pumps in 60 percent of households. In 2022, Finland installed more of the appliances per capita than any other country in Europe, while Sweden has similarly gone all-in on the technology. In the United States, heat pumps are selling like hotcakes in Alaska, and last year Maine announced it had reached its goal of installing 100,000 of the devices way ahead of schedule. These places ain’t exactly perpetually sunny California. (US-wide, heat pumps now outsell gas furnaces.)
I will professionally die on this hill. I’ll go as far as to say that people who say that heat pumps don’t work in cold climates is on par with people who don’t believe in climate change, that the world is round, etc.
