That's pretty amazing. Is floor heating enough in the winter? Can you turn up the temperature if needed? In the house I am in right now the floor heating is not enough, they had to add radiators. All electric.

More than enough, but they are all new houses and have great insulation (Triple glass everywhere etc.)

Would be more efficient to add a air-to-air heat pump rather than pure electric heating?
