Interesting. I guess you can manage with slightly reduced temperatures a few days a year. Our heat pump cycles on and off even during the coldest weather, I suspect it's oversized.

don't forget modern variable speed pumps hide this a bit. if its a variable heat pump and its cycling on/off on the coldest day then its massively oversized. thats because it should simply slow down rather than turn off.
my lounge one is about right, it constantly run at normal cold weather and struggles to heat the lounge on those coldest days. however my bedrooms ones all heat up then turn off, they are way oversized.
this is why you need to check what the minimum output of the heat pump is.

Yeah I think it's oversized. Plus in winter we don't really turn it off, the house is fairly well insulated, so it's too powerful. On the coldest days it's definitely on more. Overnight we were fine with 1000W oil heaters in the bedrooms, even they weren't on all the time, so the minimum power output of 4kw when about 500w is required means a lot of cycling.
