There are also electric hot water system rebate options from time to time, helping households move away from gas hot water. With rebates and solar combined, many Mount Coolum households see payback periods shrink to just a few years, especially if they use timers or solar diversion so their energy efficient hot water system runs mainly on daytime solar.
