It’s time to get a little technical, but the tempering & thermostatic mixing valve installation and maintenance service that we offer at Watertight Group is one of the most critical services for our commercial clients. We go into some level of detail below, but if you want further explanation, please don’t hesitate to contact us on 1300 745 758.
In basic terms, a tempering valve is a valve that prevents burn injuries. It works by controlling the temperature that supplies your tapware. It reduces the temperature to a safe temperature typically below 50°C. At Watertight Group we can give you advice on tempering & thermostatic mixing valve installation and maintenance.
There are regulations on water storage temperature. The regulations were introduced to regulate hot water temperature storage to a minimum of 60°C (AS3500.4.2 Clause 1.6). This is in order to prevent deadly legionella bacteria, which breeds in warm water under this temperature.
Tempering & thermostatic mixing valve installation and maintenance is mandatory on all new mains pressure hot water unit installations. Tempering valves are also required to be installed when an old unit is being replaced. Over 80% of scalds and burns requiring admission to hospital are caused by hot water and are caused primarily from immersion in baths containing water heated to unsafe temperatures or as a result of young children turning on hot taps whilst bathing. By having a tempering valve installed on your hot water supply it would take a whole five minutes of exposure (at 50°C) to cause a full thickness burn.
Approximate contact times to receive a third-degree burn:
- At 70°C – 1/sec adult – 0.5/sec child
- At 60°C – 5/sec adult – 1/sec child
- At 55°C – 30/sec adult – 7/sec child
- Below 50°C – approx. 5 mins adult/child
