Hot Water Tempering Valves 

How does a Tempering Valve Work?

Tempering valves blend hot and cold water to deliver mixed water at a constant temperature. They incorporate a temperature sensitive element which expands and contracts depending on the temperature of the water flowing across it. Tempering valves work by mixing hot and cold water together to supply a tempered hot water temperature no higher than 50 degrees.

This action of the element in turn moves a piston which shuttles between the hot and cold ports. In doing so the valve maintains an essentially constant outlet temperature, and thus reduces the risk of scalding accidents. When replacing an old hot water system you must install a tempering valve to comply with the current Queensland Govt Law.

There are a number of different tempering valves available with each being specific to a particular plumbing application throughout your household or business.

In all new homes or renovations it is compulsory to install tempering valves to service all bathing areas.

Blue Cap Heat GuardTempering Valve

This valve is probably the most commonly found and is for use in conjunction with electric and some heat pump water heaters. RMC HeatGuard tempering valves are suitable for domestic and commercial installation on water heater systems. The HeatGuard is available in 15 mm and 20 mm diameter with with male compression fittings.

Green Cap HeatGuard HP Temping Valve

This High Performance valve is suitable to gas hot water systems including gas storage, continuous flow and instantaneous models. 

Orange Cap HeatGuard Ultra Tempering Valve

This ultra/high performance valve is for use with solar hot water and heat pump hot water systems. The HeatGuard Ultra is a high performance tempering valve specifically designed to withstand the extreme thermal demands of solar water installations. The high performance design of the HeatGuard Ultra makes it suitable for instantaneous and continuous flow installations or any demanding installation where you would previously use a HeatGuard HP or HeatGuard Solar HP. The HeatGuard Ultra is available in 15 mm and 20 mm nominal diameters with male compression fittings.

Black Cap HeatGuard HF Tempering Valve

The HeatGuard HF is a high flow tempering valve suitable for domestic and commercial applications where high flow rates with a low head loss are required. It is also recommended for low pressure or gravity fed systems. The HeatGuard HF is available in 20 mm nominal diameter with male compression integral union fittings.

Black Cap Nefa Tempering Valve

For large capacity systems and low pressure gravity feed systems.

Orange Cap HeatGuard Solar HF

The HeatGuard Solar HF is a high flow tempering valve suitable for domestic applications where high flow rates with a low head loss are required. The HeatGuard Solar HF is specifically designed to withstand the extreme thermal demands of solar water installations. The HeatGuard Solar HF is also recommended for low pressure or gravity fed solar installations. The HeatGuard Solar HF is available in 20 mm nominal diameter with male compression fittings.

Yellow Cap Nefa Tempering Valve

These tempering valves are suitable for solar domestic and commercial installation on water heater systems.
They are available in 15 mm and 20 mm nominal diameters with with male compression integral union fittings.

Anti Scald Devices Thermostatic Mixing Valves

Hot water can burn like fire.

• It takes just 1 second for a child to receive third degree burns water between 65 and 80 degrees Celsius.
• Even at 50 deg C a child's sensitive skin can burn enough to require hospitalisation and may result in scarring.
• The best way to prevent scalds is to reduce the temperature at the bathroom with an approved Thermostatic Mixing Valve.
• Thermostatic Mixing Valves work by mixing hot and cold water together to reduce the temperature of the hot water.

Our service vehicles are fully equipped to carry out all kinds of tempering valve and thermostatic mixing valve testing, repairs and new installations even hot water repairs to all major brand Hot Water Systems, Hot Water Heaters, Hot Water Tanks and Hot Water Units.
