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 . The storage of water at high temperature removes one possible breeding ground for Legionella; the use of a thermostat, rather than a static ...
The classic thermostatic radiator valve contains a plug, typically made of wax (forming a wax motor ), which expands or contracts with the surrounding temperature. This plug is connected to a pin which in turn is connected to a valve. The valve gradually closes as the temperature of the surrounding area increases, limiting the amount of hot ...
