Hotwater diversion

Hot water diversion systems divert hot water draw-off (cold water in the hot water pipe) until the hot water at the fixture reaches the set temperature. The diversion is triggered by the operation of the hot water tap, and the water is stored in a hot water diversion tank. This water is available as an alternative water source for toilet flushing.

If a hot water diversion system is selected the saved diverted water will be automatically nominated as the alternative water source for toilet flushing in BASIX.

To maximise the water saving benefits, the system must be permanently connected to not less than all shower fittings, kitchen sinks, and all basins located within the dwelling. This will require discussion with your plumber/hydraulic designer, to ensure they understand the plumbing requirements for these systems, and factor this in during design/installation stages of the development.

Further information and installation advice is available from the respective manufacturers of these systems.

Note: a hot water diversion system is not an instantaneous hot water system. For further information on hot water systems, refer to the help notes within the 'Energy' section.
