Hot water systems in Gordon
Across Gordon, more locals are swapping old gas and electric units for an energy efficient hot water system that keeps bills down without sacrificing comfort. With mostly separate houses and an average household size of around 2.7 people, many families and downsizers are looking at whether a modern heat pump hot water system, solar hot water system or efficient electric hot water system is the smartest next upgrade.
Energy prices keep rising, and hot water can quietly chew through a big chunk of a home’s electricity use. Gordon’s solid median household income and high rate of homes owned with a mortgage mean there is a real focus on long-term running costs, not just the upfront hot water system price. Swapping from older gas or resistive electric to an energy efficient hot water system can deliver strong Annual Hot Water Energy Savings for Gordon households, especially when paired with rooftop solar.
The local climate helps too. The nearby Finlayson weather station records an average annual solar exposure of about 15.2 MJ/m² per day, which is roughly 4.2 kWh/m²/day. That level of sunlight is well suited to both a solar hot water heating system and modern heat pump hot water, which effectively "amplifies" the energy in the air. For many homes, that makes heat pump vs solar hot water a genuine choice rather than a compromise. Brands like Rheem solar hot water, Rinnai solar hot water, Chromagen solar hot water and premium options such as Sanden heat pump units are all seen in the mix locally, alongside rheem heat pump hot water for all‑electric homes.
In the 3345 area, there have already been 66 efficient hot water installations (heat pump and solar) recorded, with a noticeable spike around 2009 and renewed activity from 2017 through to 2025. Years like 2009 and 2017 saw clear peaks, and the steady trickle of recent installs shows growing interest in electrification, lower running costs and getting off bottled or mains gas. For many Gordon households, hot water VIC upgrades are happening at the same time as solar panels or other efficiency improvements.
When you look at hot water energy use compared with overall household demand, the savings from upgrading are significant. Typical annual bill reductions in Gordon might look like:
• Old electric to heat pump hot water system: save around $350–$700 per year • Gas to heat pump hot water system: save around $250–$500 per year • Gas to solar hot water system: save around $200–$450 per year • Old electric to modern electric hot water with solar: save around $200–$400 per year
Choosing between a solar hot water system, a heat pump hot water system and a modern electric hot water system often comes down to roof space, budget and whether you already have solar PV. A well‑designed solar hot water installation or heat pump hot water installation can deliver the most efficient hot water system performance, particularly when paired with timers or solar diversion. For some homes, a straightforward electric hot water installation using off‑peak tariffs or solar excess is still a solid option, especially with an electric hot water system rebate available in some programs.
Many Gordon homes are now comparing solar hot water vs electric hot water and electric hot water vs gas hot water when their old tank fails. That might mean a solar hot water tank replacement, a switch to the best heat pump hot water system they can afford, or a staged move to an all‑electric home. Local installers regularly work with popular brands like Rheem, Rinnai, Sanden and Chromagen to match the best hot water system Australia has to offer with each household’s needs and hot water system cost expectations.
Hot Water Rebates, Tariffs & Savings
Right across Gordon, there is growing interest in replacing old gas or electric hot water with efficient options such as heat pumps, newer electric units and solar hot water. Homeowners can often tap into a mix of Australian Government incentives and state-based support. Federal Small‑scale Technology Certificates (STCs) reduce the effective heat pump hot water price or solar hot water price at the point of sale, while Victorian schemes can add a heat pump hot water rebate, solar hot water rebate or hot water rebate vic that further lowers the upfront cost. In practice, these discounts can slice the installed heat pump hot water cost or solar hot water system price by a substantial percentage, meaning payback periods can drop to just a few years, especially if you already have solar. Add smart controls, timers or solar‑diversion, and an energy efficient hot water system can shave hundreds of dollars a year off bills while cutting emissions.
If your Gordon home still runs on an older gas unit or a power‑hungry electric tank, now is a good time to check whether a hot water upgrade makes sense.
