Hot water systems in Finniss
Across Finniss and the wider 5255 area, more households are rethinking their hot water system as power prices rise and older gas units reach the end of their life. With an average household size of around 2.5 people and more than 3,800 occupied dwellings, reliable, affordable hot water is a big deal for local families and retirees alike.

Finniss enjoys strong sunshine, with mean daily solar exposure of about 16.8 MJ/m², or roughly 4.7 kWh per square metre per day. That makes a solar hot water system or solar hot water heating system a natural fit, especially if you already have rooftop solar. It also supports excellent performance from a modern heat pump hot water system, which effectively uses the outside air as a heat source. Upgrading from an old gas or electric hot water system can trim a big chunk off your annual hot water energy use, which is often one of the largest single loads in the home.
In a postcode where the median household income sits around $1,364 per week and many residents are on fixed or modest incomes, choosing the most efficient hot water system really matters. Families and older couples in Finniss are increasingly comparing heat pump vs solar hot water, as well as solar hot water vs electric hot water, to find the best balance of up‑front hot water system price and long‑term savings. Brands like Rheem solar hot water and Rinnai solar hot water are common choices for roof or ground‑mounted systems, while premium heat pumps such as Sanden heat pump units and Rheem heat pump hot water are popular for all‑electric homes aiming for the most efficient hot water system possible.
Across the 5255 postcode, 471 efficient hot water systems have already been installed, combining heat pump hot water installation and solar hot water installation. Install numbers climbed sharply around 2003–2010, peaking in 2009, and while yearly installations have eased back, there is steady ongoing interest in electrification and lower running costs. Each new hot water installation helps households move away from gas, especially when paired with solar power, timers or smart controls that prioritise daytime heating.
Typical annual savings for Finniss homes switching to efficient systems can be substantial:
• Old electric to heat pump hot water system: save roughly $350–$700 per year on bills. • Gas to heat pump hot water: save around $250–$600 per year, depending on gas tariffs. • Gas to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water installation with good solar: save roughly $200–$450 per year.
When you factor in a realistic heat pump hot water price or solar hot water price, these bill reductions can deliver attractive payback periods, especially once rebates are applied. If your existing solar hot water tank replacement is due, it is a good time to compare the best heat pump hot water system options as well.
