How are people with heat pumps faring? (lemmy.ca)

With the cold weather I was hoping to hear of some experiences people have had with their heat pumps.

What kind of backup heat do you have? Are you using it? Is there some temperature where you just stop using the heat pump, or are you even consciously thinking about it?

Thanks!

Senville claims that some models are good to -30C. Even their "cheap" stuff seems to be good to -15 or -20

Keep in mind that while the heat pump works at low temperatures, it produces less heat. Senville’s 36000BTU unit produces just 27000 BTU at 17f per AHRI. The drop in output is an important consideration when evaluating system sizing and backup/auxiliary heating.

Thanks for the additional information! I'm still trying to get past all brochures and promotions to real data.

I have found NEEP’s tool extremely useful
