Check out some of the comparisons here on different hot water heater brands and the Australian Government tested and allocated STC rating.
The STC is a rated saving that a hot water system has been granted after testing and approved by the Australian Clean Energy Regulator. The number of STC’s that are issued refers to one megawatt hour (1 MWh) of avoided energy consumption over the hot water system’s deemed life expectancy.
S = R – T where S is STC count, R is Reference conventional system’s energy consumption (MWh over ten years), and T is Tested system’s estimated energy consumption (MWh over ten years).
Here is a graph showing savings and ratings of STC assigned to Active Solar hot water systems and the approximate percentage of power savings compared to a conventional electric water heater in Zone 3.
