Great idea for cities with the infastructure, but rough for those without.
Running the piping would be way, way more expensive than subsidizing stand alone heat pumps, which are 3x more efficient than even excellently efficient electric furnace.
They also provide cooling in summer months, so its a win year round.
District water loop heat pumps also have that piping cost, but has significant efficiency benefits. Both in spring and winter when some homes might need heating while more sunny ones need cooling, as well as the ability to use lake, river, or ocean as the heat source in the middle of winter as compared to much colder air.
