    KW-Zulauf = Kaltwasser-Zulauf = Cold water input Temperaturregler =Temperature regulator Abgang = Outlet Mengeneinstellung = Volume control. A thermostatic mixing valve (TMV) is a valve that blends hot water with cold water to ensure constant, safe shower and bath outlet temperatures to prevent scalding.

  3. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    Achieving cooler temperatures: Tankless water heaters often have minimum flow requirements before the heater is activated, and this can result in a gap between the cold water temperature, and the coolest warm water temperature that can be achieved with a hot and cold water mix. Maintaining constant shower temperature: Similarly, unlike with a ...

  6. Thermostat - Wikipedia

    en.wikipedia.org/wiki/Thermostat

    A thermostatic mixing valve uses a wax pellet to control the mixing of hot and cold water. A common application is to permit operation of an electric water heater at a temperature hot enough to kill Legionella bacteria (above 60 °C, 140 °F), while the output of the valve produces water that is cool enough to not immediately scald (49 °C, 120 ...
