Thermostatic Mixing Valves

hotwaterThermostatic Mixing Valves are used to protect the general public especially the elderly and the very young, from the scalding effects of water that is too hot.

East Coast Water Pty Ltd can provide proper installation, maintenance and annual testing which will ensure safer hot water settings for all households.

How can Hot Water be dangerous?

People often injure themselves in the shower by slips and falls in reaction to a sudden increase or decrease in water temperature and in the case of the elderly and the very young the loss of the cold water can cause severe burns due to the lack of movement or slow reaction to feeling the hot water.

Ideally, if the supply of cold or hot water is lost, the water flow should be shut down immediately, preventing scalding, burning and dangerous reactions from moving too quickly away from a too hot or too cold water stream resulting in injury.


A thermostatic mixing valve (TMV) is a valve that blends hot water with cold water to ensure there is constant, safe shower and bath outlet temperatures, preventing scalding.

The storage of water at high temperature removes one possible breeding ground for Legionella; the use of a thermostat, rather than a static mixing valve, provides increased safety against scalding, and increased user comfort, because the hot-water temperature remains constant.
