Hot Water Rebates, Tariffs & Savings
For Longerenong homeowners, hot water vic rebates and incentives are helping to bring the hot water system price / cost down. The Federal Government’s Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively acting as an upfront discount. On top of that, Victorian programs can offer a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate when you replace an old, inefficient unit. Combined, these hot water rebate vic offers can reduce system cost by a substantial percentage and shorten payback periods to just a few years, especially if you run your system on solar or off‑peak tariffs. Many locals are also using timers or solar‑diversion controls so their solar hot water vs electric hot water choice works hand‑in‑hand with rooftop solar for maximum savings.
If your current hot water system is more than 10 years old, running out of hot water, or needing frequent hot water repair, it is a good time to compare heat pump hot water price / cost and solar hot water price / cost against simply replacing like‑for‑like. In many cases, the most efficient hot water system will be cheaper to run over its lifetime, even if the upfront cost is a little higher. Local specialists can also help with solar hot water repair, solar hot water tank replacement and hot water repair on existing electric units.
