Installations peaked around 2009, with steady numbers through the 2010s and continued activity up to 2021. This trend reflects growing interest in electrification, hot water repair and replacement, and cutting running costs with energy efficient hot water system options instead of sticking with ageing gas units. Many households are now weighing up heat pump vs solar hot water, or comparing solar hot water vs electric hot water and even electric hot water vs gas hot water, to find the best hot water system Australia can offer for their budget.
Hot Water Rebates, Tariffs & Savings
Around Coolaroo, more residents are replacing old gas or resistive electric systems with efficient options such as heat pumps, modern electric hot water systems and solar hot water. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount on the solar hot water price / cost or heat pump hot water price / cost. On top of that, Victorian schemes can offer a solar hot water rebate or heat pump hot water rebate, and sometimes an electric hot water system rebate when moving away from gas. For many Coolaroo homes, these hot water rebate VIC programs can cut the system cost by a substantial percentage, and when combined with rooftop solar and smart timers or solar diversion, payback periods can shrink to just a few years. Add in lower hot water system price / cost over the life of the unit, fewer hot water repair call-outs and options like solar hot water tank replacement rather than full changeover, and it is easy to see why hot water VIC upgrades are on the rise.
If you live in Coolaroo and your current unit is noisy, leaking or just costing too much, it is a good time to check whether your home is ready for a hot water upgrade. Switching from gas or an old electric unit to a quality heat pump, solar hot water system or efficient electric hot water system can reduce bills, cut emissions and future-proof your place as energy prices change.
