Hot Water Rebates, Tariffs & Savings
Spence homeowners are increasingly looking to replace ageing gas or resistive electric units with efficient hot water solutions. Federal incentives such as Small-scale Technology Certificates (STCs) can cut the effective heat pump hot water price or solar hot water price by hundreds of dollars at the point of sale. On top of this, South Australian schemes often provide a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when you move away from gas. These hot water rebate sa programs can reduce system cost by a substantial percentage, meaning payback periods for a heat pump hot water installation or solar hot water repair and upgrade can drop to as little as five to seven years, especially if you run the system on daytime solar. Using timers or smart controls to run your electric hot water installation when your panels are generating can boost savings even further.
