Regulate the water temperature on the supply side of the distribution system.
The first function of a thermostatic mixing valve in a heating application is to regulate the water temperature, however in many systems, it is not the only function of the mixing device. In systems using “conventional” non-condensing boilers, the thermostatic mixing valve can also ensure that the boiler return temperature remains high enough to prevent sustained flue gas condensation.

The primary function of these valves is to control the output water temperature.
