Hot Water Rebates, Tariffs & Savings
Across Preston there is growing interest in replacing old gas or resistive electric units with efficient options such as a heat pump hot water system, a new solar hot water heating system or a modern electric hot water system designed to work with rooftop solar. Australian Government incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water installation and heat pump hot water installation, effectively acting as an upfront discount. On top of that, state‑based hot water rebate TAS programs can include a heat pump hot water rebate, solar hot water rebate and sometimes an electric hot water system rebate when you upgrade from inefficient technology.
For Preston households, these hot water rebate TAS schemes can reduce the hot water system price / cost by a substantial percentage, often cutting thousands off a premium system. That brings the heat pump hot water price / cost much closer to a standard replacement, while still delivering hundreds of dollars in annual savings. When rebates are combined with solar and smart tariffs, payback periods can shrink to just a few years. Using timers or solar‑diversion controls so your hot water system runs mainly on cheap or free solar power can further boost savings and make your setup one of the most efficient hot water system options available.
If your current unit is older, noisy or struggling, it is a good time to check whether your Preston home is ready for a hot water upgrade. Whether you are weighing up heat pump vs solar hot water, looking at solar hot water vs electric hot water, or simply planning an electric hot water installation as you move away from gas, working with experienced hot water installers matters.
