I have a heat pump heating and cooling my basement in Atlantic Canada.

Temperatures in the winter hold steady around -20C with some dips a few times in the -40c range when accounting for windchill.

Works just fine. I keep my basement a nice 21C. Heating works well. I see lots of disinfo posted online about heat pumps not working in the cold and it’s all horseshit. Make sure you’re buying a heat pump that’s built for colder temperatures and you’re golden.

This place uses a heat-pump for cooling, in the summer, but it uses a furnace for heating.

It used to reach -20C or colder, here, in the winter…

it’s rained damn-near every week, this winter…

since there is sooo much lag, between the climate-forcing adulteration of our atmosphere,

and the actual climate’s temperature,

it looks like we’re going to be … needing to find some other planet to be inhabiting, in a century…?

Based on actual history, this planet’s current equilibrium-temperature is +5C…+6C, not anywhere near the +1.5C delusion people are still believing-in.

but when one factors-in methane ( & only that one ), that we add, it works-out to +8C…+9C planetary equilibrium… ( using methane’s 20-y equivalent, of 82.5x factor, given the current 1.3ppm to 1.4ppm that we have unnaturally added of methane )

anyways, here’s the link stating that at this atmospheric CO2 the planetary-equilibrium-temperature is between +5C & +6C, in case anyone is interested:
