A tempering valve mixes together your hot and cold water. This water is then delivered as hot tap water which is at a constant temperature. Tempering valves have a temperature sensitive element which adjusts the mix of hot and cold water depending on the temperature of the incoming water through the valve.
Failure of a tempering valve may result in little or no hot water at your place!
A tempering valve is designed to maintain a constant temperature when at the tap ware. This reduces the risk of accidental scalding, especially if you have little children.
Here at Plumbaround Pty Ltd, we can supply and install a new tempering valve to your property in no time at all, to ensure the safety of your family and ensure to you have hot water!! Adjustments to the tempering valve (if required) to the required temperature can be arranged by us on inspection.
The temperature is typically controlled by the valve to within 3% give or take. The tempering valve is to a temperature between 30 – 50 degrees. As an installer/licensed plumber, we have a duty of care to ensure that all aspects of the installation comply with the AS/NZS 3500 Plumbing and Drainage Standards, appropriate Codes of Practice and local regulations.
Tempering valves are required by law now to be installed on all new homes or renovations.
So, when replacing an old hot water system you must now install a tempering valve to reduce the temperature to 50°C or below in bathrooms.
Kitchen and laundry tap ware are still permitted to bypass the tempering valve and use the hot water directly from a standard electric or gas hot water tank.
