    As with all heating relying on water for energy transport, absolutely when building new buildings, but will cost an arm if you add it in a remodeling.

    As for solar capture in Sweden, there are a few places that try to store heat in sandpits, among others a high school in Stockholm. And on that subject the Finns must be mentioned😊 Will be interesting to follow!
