Savings are indicative only. Energy savings are based on the results from TRNSYS computer simulation modelling for electric boosted thermosiphon systems using either a small, medium or large hot water energy load compared to the energy consumption of a small, medium or large conventional electric water heater. Cost savings use the published energy tariff of a major energy retailer in each state or territory.

Actual savings will vary depending upon your location, type of Solahart system installed, orientation and inclination of the solar collectors, type of water heater being replaced, hot water consumption and fuel tariff. Maximum financial savings off your hot water bill are achievable when replacing an electric water heater on continuous tariff
