Seriously good cold-climate heat pumps are headed to the US market

  We had great heat pumps in Montana already. And if it gets insanely (-38f) cold, there’s a resistive fallback mode. But I’d wager most places aren’t gonna get to 38 below.

    Not for much longer, at least.

      Interestingly climate change also makes cold snaps worse and more extreme in some places just as much as it increases heat waves. Hence the record cold in Boston last year that destroyed hundreds of homes with frozen pipes

    I’m in PA and it doesn’t get nearly as cold here, of course. We got mini splits in 2022 that can do -33f, I think. No resistive backup for us.

    Mini splits are so, so nice.

    Heat pumps don’t work well (even the new ones coming from this article are only good to 15f) anywhere near that cold. Most are only good to about 25f. Anywhere they’re installed that drops below freezing all have a backup heat system, whether or not it’s a gas backup, or resistive electric backup.

      I am looking out my window at a heat pump in my back yard which is effective down to -15F. Your info is I think about 10 years out of date.

      I think you’re forgetting ground source heat pumps. They’ll work fine at -40 because they don’t rely on air temperature.

      They’re literally all over the Alps and you’ve been lied to
