Yeah, OK, then your point stands. In Germany the coldest winter nights we get are about -10 degrees Celsius, and at that temperature I get less than 20% range loss, but that’s partly due to the lower speeds you naturally drive on slippery winter roads. In your conditions 50% range loss might actually be realistic since heat pumps drastically lose efficiency that far below freezing
Close enough, I live in the mountains where it regularly gets down into the negative teens Fahrenheit for a few weeks in winter.
