Since the early 2000s, there have been 219 efficient hot water installations (heat pumps and solar hot water) recorded across the postcode. Installations peaked around 2010, with strong years in 2009 and 2011 as early adopters jumped on rebates.

In Catamaran, hot water tas upgrades are increasingly driven by generous incentives. Australian Government Small‑scale Technology Certificates (STCs) reduce the upfront solar hot water price / cost or heat pump hot water price / cost, while state programs can add a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate for eligible households. For many homes, these discounts can trim the installed solar hot water price / cost or heat pump hot water price / cost by a substantial percentage, cutting payback times to just a few years. Combine that with timers, smart controls or solar diversion and an energy efficient hot water system can knock hundreds of dollars a year off bills. When you compare heat pump vs solar hot water, or solar hot water vs electric hot water, local installers can walk you through what suits your roof, tariff and lifestyle.
