Hot water systems in Kewell
In Kewell, more locals are looking at their old gas and electric units and wondering if there’s a smarter hot water system for the long term. With energy prices creeping up and many homes already thinking about solar, upgrading to an energy efficient hot water system – whether that’s a heat pump hot water system, solar hot water system or modern electric hot water system – is becoming the obvious next step.
Kewell’s a small, mostly owner‑occupied community, with around 480 dwellings and about half of them owned outright. The average household size is only 2.2 people, but with a lot of three‑ and four‑bedroom homes, hot water demand is still steady. Median household income sits just over $1,000 a week, so keeping running costs predictable matters. The local climate helps too: Kewell averages about 17.3 MJ/m² of solar energy a day across the year – roughly 4.8 kWh/m²/day – which is ideal for both a solar hot water heating system and efficient heat pump hot water running on daytime solar.
In postcode 3390, hot water can be a big slice of the energy bill, especially for older electric hot water vs gas hot water systems that are past their best. Switching to the most efficient hot water system you can reasonably afford can trim hundreds of dollars a year from bills. Many households are weighing up heat pump vs solar hot water, or even solar hot water vs electric hot water backed by rooftop solar, to find the right balance of hot water system price, performance and roof space.
For Kewell’s mix of smaller households and family homes, efficient hot water systems installed in the 160–300 litre range usually cover day‑to‑day needs comfortably. Community hot water energy savings can really add up as more homes move away from old storage gas or resistive electric tanks. Brands like Rheem heat pump hot water, Sanden heat pump units, Rinnai solar hot water and Chromagen solar hot water are common choices for people chasing the best heat pump hot water system or best hot water system Australia can offer for rural conditions.
Typical annual bill savings when you combine a smart hot water installation with good tariffs and, ideally, rooftop solar look like:
• Old electric to heat pump hot water system: save about $350–$700 per year • Gas to heat pump hot water: save about $250–$600 per year • Gas to solar hot water system: save about $200–$550 per year • Old electric to modern electric hot water installation with solar: save about $200–$500 per year
Across Kewell and the wider 3390 area, there have been 38 efficient hot water systems installed, including both heat pump and solar hot water installation projects.

More recently, there have still been new installs most years, showing a steady underlying interest in electrification and lower running costs. Every new solar hot water tank replacement or heat pump hot water installation helps cut local emissions while keeping hot water reliable for households.
Hot Water Rebates, Tariffs & Savings
Right now, there’s strong interest in Kewell in replacing ageing gas or electric units with efficient options – from a simple electric hot water system rebate upgrade through to a full solar hot water installation or premium heat pump hot water system. Australian Government Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as a solar hot water rebate or heat pump hot water rebate that cuts the upfront solar hot water price or heat pump hot water price at the point of sale. Victoria also offers state‑based hot water rebate VIC programs from time to time, further reducing the hot water system cost for qualifying homes.
For many Kewell households, these incentives can shave 30–50% off the installed solar hot water cost or heat pump hot water cost, bringing quality brands like Rheem solar hot water or Sanden heat pump within reach. Combine that with typical savings of a few hundred dollars a year and the payback period can drop to just a handful of years, especially if you run your system on off‑peak tariffs or use timers and solar diversion so your energy efficient hot water system heats when your panels are producing.
If you live in Kewell and your current unit is older, noisy or running up big bills, now is a smart time to see if your home is ready for a hot water upgrade.
