These discounts can reduce upfront system cost by a substantial percentage and shorten payback periods to just a few years, especially if you already have solar or use timers and smart controls to run your system when your panels are producing.
If your hot water is unreliable, noisy, or your bills keep creeping up, it may be time to look at hot water repair or full solar hot water tank replacement rather than pouring money into an ageing unit.
