In 6100, demand for efficient hot water has been steadily building. With many homes already running rooftop solar, pairing PV with an energy efficient hot water system is an easy way to soak up excess solar and lower bills.

Hot Water Rebates, Tariffs & Savings
For Lathlain households, the numbers look even better once rebates are factored in. Federal Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems WA‑wide, effectively acting as an upfront discount on solar hot water price or heat pump hot water price. On top of that, WA and other state programs from time to time support efficient electric hot water installation, and some retailers offer an electric hot water system rebate or specific heat pump hot water rebate or solar hot water rebate deals. Combined, these incentives can reduce the hot water system price or cost by a substantial percentage, trimming payback periods to just a few years for many Lathlain homes. When you add smart controls, timers or solar diversion so your electric hot water system heats mainly during sunny hours, you can unlock even more savings. For many locals, the question has become less about heat pump vs solar hot water and more about which efficient option best fits their roof space, budget and tariff.
