Hot Water Rebates, Tariffs & Savings
Across Hoffman, there is strong interest in replacing old gas or electric hot water with efficient options like heat pumps, modern electric hot water systems or a solar hot water system. Homeowners are keen to cut bills and future‑proof their homes, especially with many residents on fixed incomes and a sizeable over‑65 population. A key advantage is the range of incentives available. At a federal level, Small‑scale Technology Certificates (STCs) effectively act as an upfront discount on eligible solar hot water systems and heat pump hot water systems, reducing the hot water system cost at the point of sale. On top of that, state‑based programs can provide a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate for certain all‑electric upgrades in WA from time to time.
These rebates and discounts can slice the installed heat pump hot water cost or solar hot water price by a substantial percentage, bringing high‑efficiency systems within reach of more Hoffman households. Combine that with hundreds of dollars per year in bill savings and the payback period can be surprisingly short, especially if you already have rooftop solar and use timers or solar diversion controls to run your electric hot water system when the sun is shining. The result is a genuinely energy efficient hot water system that works with your solar rather than against it.
If you are in Hoffman and your existing unit is old, noisy or struggling, this is a great time to check whether your home is ready for a hot water upgrade. Whether you are moving from gas or an ageing electric unit to a heat pump hot water system or a solar hot water heating system, working with experienced hot water installers who understand hot water WA conditions is essential. With strong local solar, a community that cares about energy efficiency and plenty of separate houses with good roof space, efficient hot water systems can help you cut bills, reduce emissions and future‑proof your home.
