Thermostatic controls

Healthy adult skin requires only 30 seconds of exposure to water at 55 degrees centigrade before third-degree burning occurs. At 70 degrees centigrade burning occurs in less than a second. The skin of children and older people is even more sensitive to extreme temperatures. A maximum hot water temperature of 40 degrees is recommended for showers, 43 degrees for a bath and 48 degrees for the kitchen sink

Products called thermostatic mixing valves (TMVs) are available to accurately control the temperature of water for showering, bathing and hand-washing. These valves also maintain the pre-set temperatures even if the water pressure varies when other appliances are used. Installed and maintained correctly, they can significantly reduce the risk of scalding in the home. Some types of thermostatic mixing valves can be installed with existing conventional taps, others can replace existing taps.
