“Heat pumps are extremely popular in cold countries.
In fact, the top four European nations with the most heat pumps per person – Norway, Sweden, Finland, and Estonia, respectively – are some of the chilliest places on Earth.
In Norway, where the average winter temperature is -6.8°C, an incredible one in four people own heat pumps.
And the European countries moving the quickest to adopt heat pumps are Lithuania and Poland – which are also among the coldest, with temperatures often falling below freezing.”
