Installations grew steadily from just 14 systems in 2001 to over 100 a year through the mid-2000s, peaking around 2004–2007 as early solar hot water rebate programs and interest in hot water QLD incentives kicked in. While yearly numbers have eased back to 20–40 systems a year more recently, the ongoing stream of installations in 2022–2025 shows a steady shift towards electrification, lower running costs and hot water repair or replacement with efficient options rather than like-for-like gas.
Hot Water Rebates, Tariffs & Savings
Innisplain homeowners are increasingly replacing old gas or resistive electric units with heat pumps, modern electric hot water systems or a solar hot water system to get ahead of power price rises. Federal incentives, such as Small-scale Technology Certificates (STCs), can reduce the solar hot water price / cost or heat pump hot water price / cost by effectively knocking thousands off the upfront bill. On top of that, Queensland hot water rebate QLD programs have at times supported heat pump hot water rebate offers and electric hot water system rebate schemes, depending on the system type and your eligibility.
When you combine these rebates with smart tariffs, timers or solar-diversion, many Innisplain households can cut hundreds of dollars a year from bills and shorten payback periods to just a few years. That makes options like rheem solar hot water, rinnai solar hot water or a Sanden heat pump very competitive on hot water system price / cost compared with simply replacing an old gas hot water unit. For some properties, a well-sized solar hot water tank replacement or electric hot water vs gas hot water switch to an all-electric home can be the most cost-effective path.
If your existing system is ageing, noisy or needing frequent hot water repair, it may be time to look at the best hot water system Australia can offer for your style of home.
