In Teddington, more locals are rethinking their hot water system and moving away from old gas and power‑hungry electric units. With energy costs rising and many households on modest incomes, an energy efficient hot water system is becoming a smart upgrade, not a luxury. The area’s strong solar exposure – around 18.9 MJ/m² a day, or roughly 5.25 kWh/m² – makes both a solar hot water system and a heat pump hot water system a great fit for our climate.

For many homes, swapping from older gas or an ageing electric hot water system to a modern heat pump or solar hot water heating system can slash the energy used for hot water, which is often one of the biggest loads on the power bill. Annual hot water energy savings in Teddington can easily reach hundreds of dollars a year, especially when you combine an efficient hot water upgrade with rooftop solar. Modern electric hot water installation on a timer, or linked to solar, can also work well for smaller households or units that may not suit roof‑mounted collectors.

Hot Water Rebates, Tariffs & Savings
For Teddington homeowners, the numbers look even better once you factor in incentives. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively acting like an upfront discount on the heat pump hot water price or solar hot water price. On top of that, Queensland hot water rebate QLD programs and other state‑based schemes can offer a heat pump hot water rebate or solar hot water rebate that cuts the hot water system price / cost by a substantial percentage. In some cases, combined rebates and STCs can trim thousands off a quality Rheem heat pump hot water or Sanden heat pump system, bringing the payback period down to just a few years. There are also options for an electric hot water system rebate when you move away from gas hot water, helping make electric hot water vs gas hot water a much easier decision. By using timers, smart controls or solar‑diversion, you can push even more of your hot water use into sunny hours, boosting savings and making your hot water QLD upgrade truly future‑proof.
