Locally, more people are replacing old gas or resistive electric units with efficient options like heat pumps, newer electric hot water systems or a solar hot water heating system. For Waterloo homeowners, several incentives can help. The Australian Government’s Small‑scale Technology Certificates (STCs) effectively act as an upfront discount on eligible heat pump and solar hot water systems, reducing the solar hot water price / cost or heat pump hot water price / cost by a substantial percentage. On top of this, Tasmanian hot water rebate TAS programs can offer a heat pump hot water rebate or solar hot water rebate for qualifying homes, and there may be an electric hot water system rebate when shifting away from gas.
When you combine these incentives with off‑peak tariffs, timers or solar diversion to run your system when your panels are generating, payback periods can drop to just a few years. For many households, that means hundreds of dollars a year in savings, especially when choosing the best hot water system Australia can offer for your budget and site.
