Best Thermostatic Shower Valve
A thermostatic valve also known in full as a thermostatic mixing valve (TMV) is a valve that blends hot water with cold water to ensure constant, safe shower and bath outlet temperatures, preventing scalding. The TMV will shut off in the event of cold or hot water supply failure.
This can prevent scalding. It increases user comforts as when you or your guest go into the shower the water is never too cold ( thermal shock)nor too hot ( scalding). The latter happens when you have a static mixing valve in your home.
Thermostatic Shower Valve for 2019
Ideally water should be stored at a high temperature which removes the breeding ground of Legionella. Many TMVs use a wax thermostat for regulation. They also shut off rapidly in the event of a hot or cold supply failure to prevent scalding or thermal shock.
Indeed in many countries storage water temperature for building is regulated .It must be kept above 60 degrees C( 140 F) but should be circulated at temperature below 50 C (122F)as anything above that can leading to scalding injuries.
Not only does a TMV ensure constant temperature of the water it also reduces over consumption of hot water direct from a supply that is maintained at a higher temperature.
There are three categories of ways in which water temperature can be controlled.
1. Heat source . This is used in central heating systems.
2. Group control . This allows for uniform distribution of all hot water outlets in a household.
3. Point of Use . Water temperature controlled at the point of use by TMV, ( also called thermostatic facets” Thermostatic taps and or thermostatic valves.
Having TMVs at your home is the favored way of ensuring constant water temperature- eliminating the possibility of scalding especially for kids , regardless of different pressure or flow from either the hot or cold water inlets. The TMV will also shut down if either the hot or cold water supply fails.
There are a wide choice of TMVs some of which are well designed such as the Honeywell, Kohler and Danze,which will enhance the look of your bathroom.
