THE DANGERS OF HOT WATER
Every year, thousands of people suffer serious thermal shock or scalding injuries in their bathtubs, sinks and showers. Additional untold numbers become ill due to water-borne bacteria, such as Legionella.
Often, injuries in the shower are caused by slips and falls in reaction to a sudden increase or decrease in water temperature. Ideally, if the supply of cold or hot water is lost, the water flow should be shut down immediately. Termination of flow would eliminate the instinctive but dangerous reaction to move quickly away from a too hot or too cold water stream.
WHAT IS A TEMPERATURE CONTROL DEVICE?
A temperature control device is a valve designed to maintain the temperature of your hot water as a safe level to avoid scalding
There are two main types of valves commonly used in Australia which are:
- Thermostatic mixing valves (TMV’s) &
- Tempering valves
A thermostatic mixing valve is a more reliable and commercial valve that would usually be found in: Schools, Hospitals & Aged
A tempering valve works on rations not temperature and is found on most domestic hot water installations and in some small commercial scanarios.
