Submitted by Baerbel Epp on July 27, 2009

The Government of Western Australia aims to increase the efficiency of water heating systems in new residential buildings.  The 5 Star Plus energy and water efficiency requirements stipulate that new home builders install either an energy efficient gas water heater, a solar water heater or a heat pump (see table below). “We give homeowners the choice”, says Angela Heymans from the state’s Department of Commerce. All three types of hot water heating systems are approved as being highly efficient by the Sustainable Energy Development Office in Western Australia.
