SAVA - Thermostatic Mixing Valve

Thermostatic mixing valve (TMV) blends hot water with cold water to ensure constant, safe shower and bath outlet temperatures, preventing scalding.

A tempering valve is accurate to around 3℃ +/-, while a thermostatic mixing valve can keep the water to 1℃ +/- and responds faster than a tempering valve to changes in incoming water temperature. ... TMV's are designed specifically for use in facilities used by high-risk persons such as: aged care centres.

Thermostatic mixing valve neutralizes both threats by allowing water heater to be set to temperature high enough to reduce harmful bacteria, yet the mixing action maintains an appropriate outlet water temperatures to the fixtures and allows occupants to use the sinks, showers or tub with peace of mind.

Thermostatic mixing valves on your water heater are essential to prevent scalding and control the temperature of hot water at the delivery point.
