Hot Water Rebates, Tariffs & Savings
Around Dover Gardens, we are seeing more households retire old gas or ageing electric systems and install a new energy efficient hot water system instead. Federal incentives like Small‑scale Technology Certificates (STCs) apply to both solar hot water installation and eligible heat pump systems, effectively cutting the hot water system cost at the point of sale. On top of that, South Australian heat pump hot water rebate and solar hot water rebate programs can further reduce your out‑of‑pocket heat pump hot water cost or solar hot water price, sometimes knocking thousands off the total.
