The performance of each hot water system was modelled based on installation in Australian climate zone 3 and the standard AS/NZS 4234:2011. An electric storage hot water system was found to have the largest carbon footprint and energy use over its life cycle. A consumer could reduce their carbon footprint but replacing an electric hot water system with either a gas or solar electric system. The energy consumed by the hot water systems in heating water accounted for 87% to 99% of the carbon footprint of all systems. The carbon footprint and embodied energy payback periods of the solar hot water systems were found to be less than 12 months.
