Hot water rebates, tariffs & savings
Interest in replacing old gas or electric hot water with efficient options is growing quickly in Dandenong, VIC. Many households are looking for the most efficient hot water system they can reasonably afford, especially as hot water system price and ongoing power costs both matter. Federal incentives such as Small scale Technology Certificates (STCs) apply to eligible solar hot water installation and heat pump hot water installation, effectively reducing solar hot water price and heat pump hot water price by hundreds of dollars at the point of sale. On top of this, the Victorian hot water rebate VIC programs can support heat pump or solar choices, and there may be an electric hot water system rebate when switching away from gas.
