An electronic mixing valve is a type of thermostatic mixing valve. It is installed as part of a hot water system in order to mix hot and cold water together.
The valve typically includes a temperature sensor and electronic controller which can be used to control water temperature by adjusting the hot/cold water mixture.
With a digital thermostatic mixing valve, water can be stored at higher temperatures. Storing water at high temperatures helps prevent the growth of waterborne bacteria and helps save on energy costs.
By mixing hot and cold water on demand, less hot water is used when a faucet or appliance is turned on. That means your water heater doesn’t need to run as often.
Ultimately, a thermostatic mixing valve can cut residential hot water costs by up to 40 percent.
