What Valves Do I Need?

Every Hydrotherm hot water system comes with a HT-55 Pressure & Temperature Relief Valve (PTR) as standard. When installing the hot water system a plumber may be required to provide a tempering valve, high performance pressure limiting valve, isolating valve and cold water expansion valve. The valves the plumber will use is dependant on your existing hot water system and the state or council that the installation is occurring. Every council has there own set of laws and legislation regarding the installation of hot water systems, so well we can provide guidelines , it is always best to check with your installing plumber.


The cost of these valves can be between $150 – $250, these are a requirement for warranty compliance.
