Hot Water Rebates, Tariffs & Savings
For Heath Hill VIC homeowners, the combination of federal and state incentives makes upgrading far more attractive. The Australian Government’s Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively acting as an upfront discount. On top of that, the Victorian hot water rebate VIC programs can provide a heat pump hot water rebate or solar hot water rebate that can reduce the heat pump hot water price or solar hot water price by a sizeable percentage. There are also electric hot water system rebate options when moving away from gas to an efficient electric hot water installation.
When you compare heat pump vs solar hot water, both can cut hundreds of dollars a year off bills, with payback periods often shortened to just a few years once rebates, STCs and solar are factored in. Using timers or solar‑diversion controls to run your hot water system when rooftop PV is generating can improve savings further and help make solar hot water vs electric hot water from the grid a clear winner. Many locals are choosing all‑electric homes, replacing gas hot water with Rheem solar hot water, Rheem heat pump hot water, Rinnai solar hot water or a high‑performance Sanden heat pump as part of a broader energy efficient hot water upgrade.
