Brands such as Rheem, Rinnai, Sanden and Thermann are common locally, with options ranging from rheem solar hot water and rinnai solar hot water through to premium sanden heat pump and rheem heat pump hot water units that are often rated among the best heat pump hot water system choices in Australia.
