In the 3311 postcode, the typical separate house with two or three bedrooms has steady but not extreme hot water demand. That makes the most efficient hot water system choices – such as a Sanden heat pump, Rheem heat pump hot water, or a compact Rheem solar hot water or Rinnai solar hot water setup – a neat fit. Local plumbers are seeing growing interest in heat pump vs solar hot water comparisons, as well as solar hot water vs electric hot water for homes that already have rooftop solar.
For many Casterton homes, realistic annual bill savings look like:
• Old electric to heat pump hot water installation: $400–$800 per year • Gas storage to heat pump: $300–$600 per year • Gas storage to solar hot water installation: $250–$550 per year • Old electric to modern electric hot water installation with solar diversion: $200–$450 per year
Brands like Sanden, Rheem and Rinnai, along with Chromagen solar hot water, are common choices when people look for the best heat pump hot water system or the best hot water system Australia can offer for regional climates. Many systems can be paired with timers or solar-diverter controls so your electric hot water system runs mostly on your own solar.
