Hot Water Rebates, Tariffs & Savings
All this activity is backed by generous hot water rebate programs. South End households upgrading to a heat pump hot water system or solar hot water system can usually claim Small‑scale Technology Certificates (STCs) under the Federal Renewable Energy Target, which effectively reduce the heat pump hot water price or solar hot water price at the point of sale. Queensland’s state‑based schemes and retailer offers can also support heat pump hot water rebate or solar hot water rebate discounts, while some newer electric hot water system rebate options are designed to help homes move away from gas.
When you compare heat pump vs solar hot water, both can cut hundreds of dollars a year off bills, with payback periods often dropping to just a few years when rebates and solar are combined. Using timers or smart controls to run your electric hot water vs gas hot water during solar hours can make an already energy efficient hot water system even cheaper to run. Many locals are also weighing up solar hot water vs electric hot water backed by rooftop PV to decide what will be the best heat pump hot water system or solar solution for their household.
