Securing Your Solar Hot Water System
Ensuring a safe and efficient hot water system is not just about the system itself but also about its accessories. One such accessory crucial for safety is the tempering valve. Let’s discuss its importance for your solar hot water system.
What Is a Tempering Valve in a Solar Hot Water System?
A tempering valve is essential for controlling water temperature. It mixes hot and cold water to maintain a regulated temperature, ensuring no one gets scalded when using hot water.
Tempering Valve vs Thermostatic Mixing Valve: Know the Difference
Both tempering valves and thermostatic mixing valves (TMVs) perform similar functions, but there are key distinctions:
- A licensed plumber with a TMV endorsement is required to install a TMV.
- TMVs respond more quickly to temperature changes and are mandatory in facilities like schools and hospitals.
- Tempering valves are generally less expensive but may have a shorter lifespan.
Types of Tempering Valves
Depending on your solar hot water system, different valves are recommended:
- Orange Cap: Suitable for heat pump and solar hot water systems.
- Green Cap: Recommended for gas hot water systems.
- Blue Cap: Ideal for electric water heaters.
Your solar repair specialist can guide you on the appropriate valve type.
Why Brisbane Homes Need a Tempering Valve
In accordance with Australian Standards (AS3500), every hot water system in Brisbane should have a tempering valve for:
- Maintaining a minimum water temperature of 60°C to prevent bacteria growth.
- Ensuring that water from taps does not exceed 50°C to prevent scalding.
Moreover, a licensed plumber must install tempering valves, and they are a requirement during:
- New hot water system installations.
- Transfers of hot water systems between properties.
- Replacements of hot water systems.
Considering the safety it provides, installing a tempering valve on your solar hot water system is highly recommended.
