Hot Water Rebates, Tariffs & Savings
Whether you are in an older Mayne unit with tired gas hot water or a newer apartment with an ageing electric hot water system, there is strong interest in switching to an energy efficient hot water system. Federal incentives like Small-scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively cutting the solar hot water price or heat pump hot water price at the point of sale. Queensland’s state-based schemes and some electric hot water system rebate offers can further reduce hot water system cost, especially when replacing gas. For many Mayne households, that can mean discounts that shave a substantial percentage off the upfront solar hot water price / cost or heat pump hot water price / cost, turning a five to seven year payback into something much shorter. Combine an efficient system with off-peak tariffs, timers or solar diversion and you can lock in hundreds of dollars a year in savings. For some, solar hot water vs electric hot water comes down to roof access, while others compare electric hot water vs gas hot water purely on bill impact.
If your current unit is rusting, you are facing a solar hot water tank replacement, or you keep needing hot water repair, it may be time to look at a full hot water upgrade rather than another hot water repair call-out.
