Heat pumps do fine down to -20C or so. The modern ones have all sorts of tricks to avoid icing. (mostly they run the cycle in reverse which is extremely efficient since you are heating the ice on the compressor with the warmer inside air)
- spockz 9mo agoThat is awesome to hear. I noticed that mine does fine sub 0, but when it is moist and around 1-4 degrees Celsius a lot of ice forms and it needs the resistive heating. I didn’t see it reverse cycle yet. But I have air-air with one outside unit connected to three inside units. It’s a Mitsubishi Heavy from 2023.
