Hot Water Rebates, Tariffs & Savings
Right across Causeway there is growing interest in replacing old gas or electric hot water with efficient alternatives – whether that is a heat pump hot water system, a new solar hot water heating system or a well‑sized electric hot water system working with rooftop solar. For homeowners looking at hot water ACT rebates, there are usually two main incentive streams: Federal Small‑scale Technology Certificates (STCs), and ACT or Federal heat pump and electric hot water system rebate programs that encourage efficient upgrades.
These incentives can significantly cut the upfront hot water system price or heat pump hot water price, sometimes reducing the solar hot water price or cost of a quality heat pump by 20–40% once discounts are applied by your installer. A solar hot water rebate or heat pump hot water rebate can bring payback periods down to just a few years, especially if you also use timers or solar diversion so your electric hot water installation runs when your PV is generating. For some homes, an electric hot water system rebate can make a modern, well‑insulated tank an appealing option when comparing electric hot water vs gas hot water or heat pump vs solar hot water.
Whether you are dealing with hot water repair on an ageing unit, planning a solar hot water tank replacement, or comparing solar hot water vs electric hot water for a renovation, it pays to get clear advice on hot water ACT options and any hot water rebate ACT programs you may qualify for.
