I'm sorry for such a long answer, my dear friend. But your question about heating houses has put me at a dead end. Never thought about it before. 😅
As it turned out, nothing extraordinary. No super pipes or powerful pressure in the pipes. Almost everything is like in the central strip. With the exception of one nuance, certain chemicals are added to tap water in winter, so that hot water retains heat for longer, and cold water withstands even lower temepartures. And of course the boiler rooms are working to the maximum. And we also pay for heating in winter 8-10 times more expensive than people in the south 😁
Not too worry, dear Northman. I think it is hot water heating then. I was just curious because of the extreme cold at times.
A lot of houses and apartments here have gotten heat pumps which are suppose to be more efficient and use less hydro. They work by transferring heat from cold air outside your home to the inside of your home and they also double as an air conditioning system in summer. Most people have a second heat source too. Wintertime costs lots to keep warm.
Have a great Thursday! 😊
