A thermostatic mixing valve is a type of valve used mainly in hot water systems.
It controls the mixing of hot and cold water, keeping the water temperature constant for user comfort.
Thermostatic mixing valves are typically found in bath and shower systems and perform the following functions:
-
Temperature Control: Mixes hot and cold water to keep the water at the temperature set by the user. When the temperature rises above a certain value, the valve automatically adds cold water and the temperature stays constant.
-
Safety: Protects the user from sudden temperature changes (e.g. the water becoming too hot or too cold), preventing scalding.
-
Energy Efficiency: By preventing temperature fluctuations, it improves system efficiency and saves energy.
-
Comfort: The user can rely on the water being kept at the desired temperature at all times, for a more comfortable shower experience.
These valves are used for showers and bathtubs and are frequently preferred in places such as hotels. Some thermostatic mixing valves also offer digital control panels instead of a "lever" or "knob" for adjusting the water temperature.
