Most Nordic cities have central heating plants for millions of homes. This water is recycled, colored bright green and have non-corrosive additives.

Helsinki has also central cooling system utilizing near-by Baltic sea. There is also yearly discussion about using the heating radiators for cooling. Unfortunately system is not designed for that and condensation will damage buildings.

90% of houses in Linkoping get heating from the power utility. https://www.tekniskaverken.se/about-tekniska-verken/products...

I think I posted a comment here about a family friend who had two heating circuits, one for the house and one for a pool which was only used/heated in the summers.

So is the Stockholm area, they also "buy" excess heat from data centers and other places and offer district cooling as well
