* Hot water delivery temperature is 48°C but displayed as 50°C. As permitted in AS 3498-
2009, delivery temperature can be adjusted above 50°C by installers. This allows for the
outlet temperature to be increased (offset) to compensate for temperature losses in the
pipework, between the water heater outlet and sanitary fixtures.
