Hot water systems in Thompson Beach
Across Thompson Beach and the wider 5501 area, more households are swapping old gas and power-hungry electric units for modern, energy efficient hot water systems. With an average household size of around 2.8 people and more than 2,800 dwellings, reliable hot water is a daily essential – and rising energy prices mean it makes sense to upgrade to a smarter hot water system that costs less to run.
Thompson Beach enjoys strong sunshine, with mean daily solar exposure of about 17.8 MJ/m², or roughly 5 kWh/m² per day over the year. That level of sun is ideal for a solar hot water system or a heat pump hot water system, especially if you already have rooftop solar or are planning an all-electric home. Many locals own their homes outright or with a mortgage, so investing in a long-term hot water installation that cuts bills and boosts property value is a logical step. Swapping from an older gas or resistive electric hot water system to an energy efficient hot water system can trim a big slice off your annual energy use, freeing up more of that median household income for other priorities.
Around Thompson Beach, most homes are three- or four-bedroom separate houses, so hot water demand is steady, particularly for busy families and multi-bathroom homes. A modern heat pump hot water system or solar hot water heating system can be the most efficient hot water system option, especially when paired with rooftop solar. Brands like Rheem heat pump hot water and Sanden heat pump units are popular for low running costs, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water systems are common choices for roof-mounted or split solar hot water installation. For some homes, a well-sized electric hot water system with smart controls still makes sense, especially when used as a solar diverter load.
Typical savings for Thompson Beach households will vary with usage and tariffs, but these ranges are realistic for many homes:
• Old electric to heat pump: save around $400–$800 per year on bills. • Gas to heat pump: save roughly $300–$600 per year, plus avoid gas supply charges. • Gas to solar hot water: save about $250–$550 per year. • Old electric to modern electric hot water installation with solar: save around $250–$500 per year.
In the 5501 postcode, there have already been 421 efficient hot water installations, combining heat pump hot water installation and solar hot water installation.

Each new hot water installation adds to community hot water energy savings and helps normalise efficient options like the best heat pump hot water system or the best hot water system Australia can offer for coastal climates.
Hot Water Rebates, Tariffs & Savings
For Thompson Beach homeowners, there is growing interest in replacing old gas or electric hot water with efficient options such as a heat pump hot water system, a modern electric hot water system or a solar hot water system. Federal incentives, like Small-scale Technology Certificates (STCs), can reduce the upfront hot water system price by hundreds of dollars for eligible heat pump and solar hot water systems. On top of that, South Australian programmes can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate, bringing the effective heat pump hot water price or solar hot water price down even further. These discounts can cut the system cost by a substantial percentage and shorten the payback period to just a few years, especially when you use timers or solar-diversion to run your hot water system during sunny times. When you compare heat pump vs solar hot water or solar hot water vs electric hot water, it is important to factor in both rebates and local tariffs so you get the most energy efficient hot water system for your situation.
