What is it/what does it do?
A thermostatic mixing valve is a device which blends hot and cold water sources to ensure that the distributed water is of a constant temperature. As well as having the great advantage of ensuring constant water temperature the thermostatic mixing valve (TMV) is also an important safety feature on all of our products as they are designed to automatically shut off the water flow if either the hot or cold water supply were to fail. This ensures that the user cannot be scalded by extremely hot water neither can they suffer thermal shock from extremely cold water.
Everyone will have unfortunately experienced a rapid change in shower temperature due to a drop in water pressure or temperature cause by somebody flushing a toilet or opening another tap in the house. This is a thing of the past with TMV’s as the valve automatically compensates for variations in supply pressures or temperatures so as to maintain a safe temperature.
There are three main types of TMV’s, they are:
- Heat Source – used in water based central heating systems
- Group Control – control the flow of water to different household appliances
- Point of Use – used in individual appliances
All of our thermostatic mixers comply with BS EN 1111 or BS EN 1287 regulations and are of the highest quality.
