Hot water systems in Davenport
Across Davenport and the wider 6230 area, more homes and businesses are swapping old gas and electric units for an energy efficient hot water system that is cheaper to run and kinder to the planet. With an average household size of around 2.4 people and more than 17,000 occupied dwellings in the postcode, reliable hot water is a must – but so is keeping energy costs under control. Many households are on mortgages or paying rent, so shifting from an ageing gas storage or resistive electric hot water system to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a logical way to lock in long‑term savings.
Davenport’s Bunbury climate is ideal for efficient hot water. The local weather station records mean daily solar exposure of about 18.6 MJ/m², which works out to roughly 5.2 kWh/m² of solar energy every day across the year. That strong sunlight boosts the performance of any solar hot water heating system and helps heat pump hot water systems run more efficiently, especially when paired with rooftop solar. For many households, hot water is the single biggest chunk of electricity use, so the potential Annual Hot Water Energy Savings from upgrading can be substantial.
In the 6230 area, separate houses dominate, with thousands of three‑ and four‑bedroom homes, which typically means higher hot water demand – showers, laundry and dishwashers all adding up. A well‑sized hot water system can dramatically cut running costs without sacrificing comfort. Local installers see strong interest in brands like Rheem and Rinnai for both solar hot water and efficient electric units, as well as Sanden and Stiebel‑style premium heat pump options for those chasing the most efficient hot water system on the market. For many, the question of heat pump vs solar hot water comes down to roof space, budget and whether there is already rooftop solar in place.
Typical savings for Davenport homes moving away from old systems look like this:
• Old electric to heat pump hot water installation: around $350–$700 per year off bills. • Gas storage to heat pump: roughly $250–$600 per year. • Gas to solar hot water installation: about $300–$650 per year. • Old electric to modern electric hot water installation with solar: around $250–$500 per year, depending on usage and tariff.
Local hot water installation data shows this is more than just talk. In the 6230 postcode there have already been 2,152 efficient hot water systems installed, combining both heat pump and solar hot water installation.

That steady pattern of heat pump hot water installation and solar hot water installation reflects growing interest in electrification, lower running costs and getting the best hot water system Australia can offer for local conditions.
For many Davenport households, the upfront hot water system price or cost is the main barrier. This is where rebates make a real difference. Federal incentives through Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively cutting the solar hot water price or cost and heat pump hot water price or cost by a meaningful percentage at the point of sale. On top of that, WA homeowners may access a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate under various state and retailer programs from time to time. When you combine these hot water rebate WA offers with smart tariffs, timers and solar‑diverter controls, payback periods can drop to just a few years, with typical savings of hundreds of dollars per year.
Whether you are comparing electric hot water vs gas hot water, weighing up solar hot water vs electric hot water, or planning a solar hot water tank replacement with brands like Rheem solar hot water, Rinnai solar hot water, Chromagen solar hot water or a premium sanden heat pump, it pays to get local advice.
