With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Windermere and the 3352 area, 1,457 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.
With Windermere's climate delivering an average of 4.4 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

With solid median household incomes and a large share of homes either owned outright or with a mortgage, upgrading from older gas or resistive electric hot water to the most efficient hot water system is a logical way to lock in long‑term savings. Many locals are seeing annual hot water energy savings in the hundreds of dollars, especially when they pair efficient systems with rooftop solar.
In the 3352 postcode, detached houses dominate and four‑bedroom homes are very common, so hot water demand is often high. That makes an energy efficient hot water system particularly attractive, because hot water energy use can be a big slice of the overall bill. Over time, more households have moved from gas to electric hot water vs gas hot water, or from basic electric to options like heat pump vs solar hot water, to cut running costs and future‑proof their home against gas price rises. Brands such as Rheem, Rinnai and Sanden are popular locally, with Rheem solar hot water and Rinnai solar hot water units a familiar sight, while premium systems like a Sanden heat pump or Rheem heat pump hot water are often chosen by those chasing the best heat pump hot water system on the market.
Typical annual bill savings in Windermere look like this:
• Old electric to heat pump hot water installation: save roughly $400–$800 per year. • Gas to heat pump hot water system: save around $300–$700 per year. • Gas to solar hot water installation: save about $250–$600 per year. • Old electric to modern electric hot water installation with solar: save roughly $200–$500 per year.

Hot Water Rebates, Tariffs & Savings
Around Windermere VIC, more people are now replacing old gas or ageing electric units with a heat pump hot water system, a modern electric hot water system or a solar hot water system to cut bills and emissions. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pumps, effectively acting as a solar hot water rebate or heat pump hot water rebate that reduces the upfront hot water system price.
