Tempering valves and TMVs are different products
Both tempering valves and thermostatic mixing valves blend hot and cold water, but they are not interchangeable names. Select the device against the building, outlet, users and applicable installation requirements.
Do not choose by facility label alone
A healthcare patient-care outlet can have different temperature and device requirements from a kitchen equipment connection. Requirements for personal hygiene outlets also differ from the temperatures needed by some equipment. A statement that one device is mandatory in every commercial kitchen is not an adequate specification.
Give the plumber a usable brief
- Identify each outlet’s use and the people who use it.
- Provide the equipment manufacturer’s inlet-temperature requirements.
- Ask the licensed plumber to identify the applicable local rule, device specification, delivery temperature and commissioning checks.
- Keep the commissioning and maintenance requirements for the exact installed device.
The NSW heated-water installation guidance is a starting reference for NSW projects. It does not establish one device or temperature for every Australian facility.
