> That heats one 100m² room, doesn't it?

A lot of both Norwegian and UK homes have open plan main floors.

Just leave all the internal doors open. The average family home in the UK is less than 100 m2 all told. A pair of air to air heat pumps would easily heat the two floors.

And of course the UK really should insulate houses better.
