  2. Heat trap - Wikipedia

    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. [1] [2] Newer water heaters have built-in heat traps.

    en.wikipedia.org/wiki/Trace_heating

    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.

  7. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    With a central water heater of any type, any cold water standing in the pipes between the heater and the point-of-use is dumped down the drain as hot water travels from the heater. This water wastage can be avoided if a recirculator pump is installed, but at the cost of the energy to run the pump, plus the energy to reheat the water ...
