Hot Water Rebates, Tariffs & Savings
Around Iwantja, more people are replacing ageing gas and electric units with efficient options. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible solar hot water system and heat pump hot water installation jobs, effectively cutting the solar hot water price / cost or heat pump hot water price / cost at the point of sale.

These hot water rebate SA schemes can trim the upfront hot water system price / cost by a substantial percentage.
When you combine rebates with rooftop solar and smart controls, payback periods for a solar hot water heating system or efficient electric hot water installation can shorten to just a few years. Using timers or solar diversion to run your hot water during the middle of the day helps you get even more value from your solar and can make an electric hot water system or rheem solar hot water unit one of the cheapest appliances to run in the house. For homes still on gas, switching to all-electric hot water SA options can simplify bills, cut emissions and reduce exposure to rising gas prices.
