Across South Wharf, owners and body corporates are increasingly eyeing off hot water upgrade options like heat pumps, efficient electric hot water and solar hot water systems as gas prices rise and sustainability expectations grow. Australian Government incentives, such as Small-scale Technology Certificates (STCs), can reduce the solar hot water price / cost and heat pump hot water price / cost by effectively discounting the upfront investment. On top of this, hot water rebate VIC programs, including state-based heat pump hot water rebate and solar hot water rebate schemes, can further lower the final hot water system price / cost for eligible homes and apartments.

Even a modern electric hot water installation can benefit from an electric hot water system rebate and smart tariffs, making solar hot water vs electric hot water comparisons much more attractive for all-electric homes.
