Better than this, I’m in QC (basically same climate as ME) and my heatpump is rated -20C/-4F and yes it works in winter to heat the house. Sometimes the heat pump goes in a “anti frost mode”, it’s automatic. I set it to 73F in winter and depending of the room it’s between 70 and 73, even if it’s -4F outside.
In QC, ME, VT, etc it can go down to -22F in winter, not uncommon. I have electric baseboard set to 70F so in case the heatpump stops, the baseboards take the relay.
-60⁰ F windchill. You always want to install the heat pump exchanger where it’s not getting battered by wind anyway, so it’s probably not feeling temps that low
Not familiar with the weather there, but there are heat pumps out there that work in temps as low as 4 degrees F.

And the article states that they’re working at -60 in Maine. They also aren’t geothermal. I’m intrigued.
I think that was -60 windchill. Which is odd, I would think the windchill temp is irrelevant. Marketing and spin I guess.
