At what ambient temperature does your ASHP noticeably start to lose efficiency?
I've seen a lot of comments about heat pump efficiency and drop off in performance when it's no longer "mild" outside. Mild will mean different things to different people, homes and heating systems, so at what ambient temperature does your heat pump start to consume a lot more power with a noticeable drop off in efficiency (COP)?
