Efficient hot water is not new to South Preston. There have already been 169 efficient hot water installations (heat pump and solar) recorded in the postcode.

Hot Water Rebates, Tariffs & Savings
Across Tasmania, more South Preston households are replacing old gas or tired electric units with efficient options such as heat pump hot water, upgraded electric hot water systems and roof mounted solar hot water. Federal incentives like Small scale Technology Certificates (STCs) apply to eligible systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that is usually taken off the purchase price by your installer. For some electric storage upgrades, an electric hot water system rebate may also apply, helping reduce the hot water system price or cost at install time. In practice, these hot water rebate TAS programs can cut the effective heat pump hot water price or cost and solar hot water price or cost by a substantial percentage, bringing payback periods down to as little as five to seven years, sometimes less if you already have solar. Combine that with smart tariffs, timers or solar diversion and you can turn an efficient unit into a truly energy efficient hot water system that shaves hundreds of dollars a year from bills.
