In which nordic country do you live? Im swedish and we have centralized water heating, and to me it sounds insane that people where you live does not have gate valves. The only time I heard of someone without that was when a friend changed the heating system in his building, and that was like a week of high temp. 30 degrees inside during winter sounds totally insane. Here we discuss that we should lower from 23 in the winter to save resources.
