Imagine living in a snowy city where hot water is pumped through the sidewalks to people’s homes. No frozen pipes, no shoveling snow. No people freezing to death…
You still need to clear snow and ice. The hot water pipes are insulated to ensure that the hot water remains hot until it goes into radiators and faucets. You’d lose all that heat if you use it to heat sidewalks.
My city does this. Hot water is pretty cheap here if you’re hooked up to the municipal network. If you have an electric water heater you’ll go bankrupt in the winter.
