Thermostatic, a type of water mixing valve, differs from digital mixing valves. Mixing valves help regulate the delivery of stored water, reduce the output of bacteria, and prevents scalding or freezing water. The idea behind mixing valves is that they keep water at a desired state and temperature. While digital valves have the advantage of doing so at a set time, don't underestimate the benefits of a thermostatic mixing valve, giving you the power to control it yourself.
Thermostatic Mixing Valve
A thermostatic mixing valve combines both hot and cold water in order to produce a consistent temperature when it exits a faucet. Thermostatic mixing valves are engineered to maintain water temperatures. Not only are they designed to prevent accidental scalding, but they can increase the amount of hot water that is available. This device can control the output of water from both a faucet and from your shower.
Digital Mixing Valves
Digital mixing valves are controlled by a sensor. In this censor the valve can be turned on by time or by a position sensor. The control system is where this digital control exists, where there is an on and off option, giving you the option to manually use the mixing valve as well. Digital Mixing Valves offer all the benefits of a thermostatic mixing valve, but with the advantage of being placed on a timer.
