When you compare heat pump vs solar hot water, the best choice in Armadale often comes down to roof space, strata rules, and whether you already have rooftop solar.
Average annual bill savings from common upgrade paths can look like this:
• 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 system with solar: $250–$500 per year

Hot Water Rebates, Tariffs & Savings
Across Armadale VIC, there is growing interest in replacing old gas or electric hot water with efficient options like heat pumps, newer electric hot water system models or a roof‑mounted solar hot water system. Homeowners can often access a mix of Australian Government incentives and Victorian hot water rebate programs that apply to energy efficient hot water system upgrades. Small‑scale Technology Certificates (STCs) apply nationwide for eligible heat pump and solar hot water systems, effectively cutting the upfront hot water system price or cost at the point of sale. Victoria also offers state‑based schemes that can provide a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when moving away from gas.
When you add these incentives together, it is common for discounts to reduce the effective heat pump hot water price or cost, or the solar hot water price or cost, by a substantial percentage. That can bring payback periods down to just a few years, especially if you already have rooftop solar and use timers or solar‑diversion to run your hot water when the sun is shining. Many Armadale households see hundreds of dollars per year in savings, particularly when shifting from electric hot water vs gas hot water to a truly energy efficient hot water system that is closer to the most efficient hot water system currently available.
