That strong sunlight supports both a solar hot water heating system on the roof and a high efficiency heat pump hot water system on the ground. For many homes, shifting from older gas or resistive electric hot water to an energy efficient hot water system can deliver substantial annual hot water energy savings and noticeably lower power bills.
With 547 occupied private dwellings and a high proportion owned outright in Wehla, many properties are at the age where a hot water tank replacement is due. Hot water installation choices now range from premium brands like Rheem solar hot water and Rinnai solar hot water through to advanced heat pump options such as Sanden heat pump and Rheem heat pump hot water. Locals are comparing heat pump vs solar hot water, solar hot water vs electric hot water and even electric hot water vs gas hot water to find the most efficient hot water system for their home, budget and roof layout.
In the 3518 postcode, 113 efficient hot water systems have already been installed, including both heat pump hot water installation and solar hot water installation. Installations peaked around 2009, when 43 systems went in, and there has been steady interest since, with new systems added almost every year through to 2025. This long-term trend shows growing confidence in all-electric homes, lower running costs and the reliability of brands like Sanden, Rheem and Rinnai. Many households that installed solar PV earlier are now adding a matching energy efficient hot water system to soak up excess solar and cut bills further.
For a typical Wehla home, hot water energy use can be one of the biggest single loads. Upgrading can deliver real savings:
• Old electric to heat pump hot water: save roughly $350–$700 per year on bills. • Gas to heat pump hot water: save around $250–$600 per year. • Gas to solar hot water system: save about $200–$500 per year. • Old electric to modern electric hot water with solar: save roughly $250–$550 per year.
When you compare heat pump hot water price or cost against solar hot water price or cost, it is worth factoring in running costs, lifespan and available rebates. Many locals find that the best heat pump hot water system or a quality solar hot water system ends up cheaper over the life of the unit than simply replacing like-for-like. For some, the best hot water system Australia can offer is a high performance heat pump such as a Sanden heat pump, paired with rooftop solar; for others, a roof-mounted chromagen solar hot water or Rheem solar hot water tank replacement is the right fit. Reliable electric hot water installation also remains popular where roof space or shading limits solar.
Hot Water Rebates, Tariffs & Savings
In Wehla, interest is growing in replacing ageing gas or electric units with efficient options supported by hot water rebate VIC programs.
