Electric and solar hot water systems

Most households use standard electric element hot water systems - and heating water is typically the second-biggest energy consumer in Tasmanian households.

Solar and heat pump hot water systems are more energy-efficient choices.

Heat pumps work by extracting energy from ambient outside air, converting it to heat, and using the warm air to heat water.

Heat pump hot water systems may use between 25 to 33 per cent less energy than a standard electric element hot water system, which may lead to a significant saving in your energy costs. While they may have a higher upfront cost than standard systems, their lower running costs offset the up-front over time, typically leading to savings after 4-6 years.

Solar hot water systems are quieter than hot water heat pumps and they may be more cost-effective to run during sunnier times of year. Unlike heat pumps, these systems are typically installed on roofs rather than against walls, from where they transfer heat from a solar 'collector' to a water storage tank. Solar hot water systems can provide most of your hot water needs, with electricity (or less commonly gas) used to boost the water's temperature when required.

If you wish, talk to your supplier about federal government policies, including the eligibility of your solar hot water system for Australian Government rebates.

Electric hot water systems approved for the ESLS can be found on the Australian Government's Greenhouse and Energy Minimum Standards (GEMS) register.

Talk with your supplier about which hot water systems are eligible under the ESLS.
