    Hot water service piping can also be traced, so that a circulating system is not needed to provide hot water at outlets. The combination of trace heating and the correct thermal insulation for the operating ambient temperature maintains a thermal balance where the heat output from the trace heating matches the heat loss from the pipe.

    en.wikipedia.org/wiki/Heat_trap

    Heat traps are valves or loops of pipe on the cold water inlet and hot water outlet of water heaters. The heat traps allow cold water to flow into the water heater tank, but prevent unwanted natural convection and heated water to flow out of the tank.

This will make the working environment more hospitable for miners, and prevent freezing of workings, in particular water pipes. In Arctic mines, where the mining horizon is above the permafrost, heating may not take place to prevent melting the permafrost.
