Hot water systems in Bonython
In Bonython, hot water is a big chunk of the power bill, so more locals are looking at an energy efficient hot water system rather than hanging onto old gas or electric units. With around 1,933 occupied dwellings and an average household size of about two people, many homes are owned outright or with a mortgage, which makes hot water upgrades an easy way to improve comfort and cut running costs. The median age here is 57, so reliability and low maintenance matter just as much as savings.
Bonython is well suited to a solar hot water system or heat pump hot water system. The nearby Palmer weather station records average solar exposure of about 17.5 MJ/m² per day – roughly 4.9 kWh/m² of sun – which is excellent for both a solar hot water heating system and modern heat pump hot water that runs efficiently during the day. Upgrading from older gas or an inefficient electric hot water system can trim hot water energy use dramatically, with typical households saving hundreds of dollars a year.
Across the 5238 postcode, most homes are separate houses with two to three bedrooms, so a 250–315 litre hot water system is usually ideal. Hot water can account for a quarter or more of household energy use, so choosing the most efficient hot water system you can afford makes sense. Locally, we see a mix of heat pump vs solar hot water decisions, with many households that already have rooftop solar leaning towards a heat pump hot water installation to soak up excess solar power. Others prefer a roof-mounted solar hot water installation with a ground or roof tank.
Typical annual bill savings for Bonython homes are: • Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water system: $300–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water installation with solar: $200–$450 per year
Brands like Rheem heat pump hot water and Rheem solar hot water are popular for their broad range and solid warranties, while Sanden heat pump systems are often chosen as some of the best heat pump hot water system options for very low running costs. Rinnai solar hot water and Chromagen solar hot water are also common choices for households wanting a premium solar hot water tank replacement or a full new solar hot water system. Many locals research the best hot water system Australia wide, then narrow it down based on hot water system price, roof space and whether they want all-electric hot water vs gas hot water.
In Bonython, there have already been 221 efficient hot water systems installed, combining heat pump and solar hot water. Installations peaked in years like 2005, 2007 and 2009, each with close to 20–24 systems going in, and there has been steady interest right through to 2024 and 2025. This ongoing pattern of hot water installation shows a clear local shift towards electrification, lower running costs and more energy efficient hot water system choices.
Hot Water Rebates, Tariffs & Savings
Interest in hot water SA upgrades is growing as power prices rise and more people move away from bottled or mains gas. Homeowners in Bonython can usually tap into a mix of Australian Government incentives and state hot water rebate SA programs. Small-scale Technology Certificates (STCs) help reduce the solar hot water price / cost and heat pump hot water price / cost at the point of sale, while state-based schemes can offer a separate heat pump hot water rebate or solar hot water rebate. In some cases, electric hot water system rebate offers apply when you replace old gas with an approved energy efficient hot water system.
With rebates and discounts, it is common for the effective hot water system cost to drop by 20–40%, which shortens payback times significantly. Many Bonython households see payback in as little as three to six years, especially when a heat pump or solar hot water vs electric hot water is paired with rooftop solar. Adding timers or smart controls so your electric hot water system runs mainly on solar can further trim bills and improve the overall value.
