Together, these hot water rebate VIC programs can cut the installed cost of a new system by a substantial percentage, making the upgrade far more affordable.
With the right combination of rebates, a quality rheem solar hot water or chromagen solar hot water system, or a high performance sanden heat pump, many Bunbartha households can trim hundreds of dollars a year from their bills. Payback periods shorten even further when the hot water is timed to run during solar production, turning excess rooftop generation into free or very cheap hot water. For many locals, that makes an energy efficient hot water system one of the easiest ways to cut emissions and future proof the home against rising gas and electricity tariffs.
If you live in Bunbartha and your current system is getting old, noisy or expensive to run, now is a good time to check whether your home is ready for a hot water upgrade.
