Hot Water Rebates, Tariffs & Savings
Right now there is strong interest in Tarnagulla in replacing old gas or ageing electric units with efficient options like a heat pump hot water system, a newer electric hot water system paired with rooftop solar, or a quality solar hot water system. For many homes, the upfront hot water system price or cost is the main hurdle, which is where rebates come in. Federal incentives such as Small-scale Technology Certificates (STCs) apply to eligible systems and effectively cut the solar hot water price or cost or the heat pump hot water price or cost at the point of sale. On top of that, Victorian programmes can provide a solar hot water rebate, a heat pump hot water rebate or even an electric hot water system rebate in some circumstances. Together, these hot water rebate VIC schemes can trim the installed cost by a substantial percentage, shorten payback periods and make options like Rheem solar hot water or a premium Sanden heat pump much more affordable.
Once installed, efficient systems can shave hundreds of dollars per year off power or gas bills. If you combine a smart tariff, timers or solar diversion so your hot water system runs mostly on your own solar, the payback period can fall even further. For many Tarnagulla homes, the long term savings and comfort easily outweigh the initial hot water system price or cost.
If you are in Tarnagulla and your hot water system is getting old, noisy or unreliable, it is a good time to compare electric hot water vs gas hot water and look at options like a heat pump hot water installation or solar hot water tank replacement. Local installers can also help with hot water repair and solar hot water repair if you are not quite ready to replace. With strong solar, a high rate of home ownership and growing interest in sustainability, Tarnagulla is well placed to benefit from efficient hot water.
