Local installers work with trusted brands like Rheem, Rinnai and Sanden, offering everything from rheem solar hot water and rheem heat pump hot water to rinnai solar hot water and premium sanden heat pump units. These options are popular with homeowners looking for the most efficient hot water system and the best heat pump hot water system for Australian conditions.
Average annual bill savings in Wandal will vary with usage and tariffs, but realistic ranges for a typical family home look like this:
