When comparing heat pump vs solar hot water, think about roof space, shading from trees, and whether you already have PV solar. A solar hot water vs electric hot water decision can be different for each home, especially if you plan to go all‑electric. Some households still prefer an efficient electric hot water system with a timer or diverter to soak up excess solar, while others want a full solar hot water heating system with a roof collector and solar hot water tank replacement for an ageing cylinder.
Hot Water Rebates, Tariffs & Savings
In WA, interest in hot water WA upgrades is rising as people move away from gas hot water and old electric units. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively working as an upfront discount. On top of that, state‑based programs can offer a heat pump hot water rebate or solar hot water rebate, and there are also electric hot water system rebate options from time to time. For many Mount Helena homeowners, these hot water rebate wa incentives can knock a substantial percentage off the heat pump hot water price / cost or solar hot water price / cost.
Once installed, a quality energy efficient hot water system can trim hundreds of dollars a year from bills, especially if you use timers or solar diversion so your electric hot water vs gas hot water costs tilt firmly in favour of electric. With rebates shortening the payback period, the real hot water system price / cost over the life of the unit can be far lower than sticking with an old gas system. The same applies to heat pump hot water price / cost when you include rebates and off‑peak tariffs.
If your current unit is leaking, unreliable or more than 10–12 years old, it is worth considering hot water repair versus full replacement. Sometimes a simple solar hot water repair or element change is enough; other times a new system is the smarter long‑term move.
