Hello everyone, recently my city has been doing some repairs to the city’s hot water system and i was without hot water for about 3 weeks.
That got me wondering, how exactly does this work? I read something about a heating agent but i don’t know what that means. And how does the water stay hot while travelling from the place it gets heated to our homes?
Thanks!

A large city by me in the Midwest US has hot and chilled water for heating and cooling buildings down town. This is recirculated back to the district energy buildings with many giant boilers for hot water and cooling towers outside for the chilled water.
These are supplied to buildings for HVAC use. Most of the large buildings downtown are on domestic instead of having their own boilers and cooling equipment.
Cold potable (drinking water) is supplied and run through a heat exchanger where the domestic hot loop heats it up to make hot water for showers etc. The now colder domestic hot goes back to the district boilers to be reheated.
Domestic hot water supply wouldn’t be consumed at least here in the states it is used in coils that make hot or cold air and heat exchanges to make potable hot water.
