With many residents over 55 and staying in their homes long term, the annual hot water energy savings from upgrading can really add up over the years.
In a postcode with more than 1,900 occupied private dwellings, most are separate houses, many with three bedrooms or more – ideal for roof space and yard room to fit the most efficient hot water system for your needs. Hot water can be one of the biggest energy users in the home, so choosing between heat pump vs solar hot water or a modern electric hot water system is an important call. Brands like Rheem heat pump hot water, Rheem solar hot water, Rinnai solar hot water and premium Sanden heat pump units are all popular for families wanting an energy efficient hot water system that will go the distance in country South Australia.
For a typical Purnong household, upgrading can deliver solid bill reductions. On average, you might expect:
• Old electric to heat pump hot water installation: save around $350–$600 per year • Gas to heat pump hot water system: save about $250–$500 per year • Gas to solar hot water installation: save roughly $200–$450 per year • Old electric to modern electric hot water installation with solar PV: save around $200–$400 per year

When older units fail, many locals now look first at the best hot water system Australia can offer in their budget, weighing solar hot water vs electric hot water and electric hot water vs gas hot water. A good installer will talk you through hot water system price and heat pump hot water price compared with solar hot water price, and whether a solar hot water tank replacement, solar hot water repair, general hot water repair or a full new hot water installation makes the most sense.
