- Scope
- This Standard sets out a method for calculating the energy consumption of electric storage water heaters fitted with electric resistance heating units. The Standard is not applicable to gas water heaters, solar water heaters, heat-exchangers or heat-pumps. NOTES: 1 This Standard is based on known performance characteristics of electric storage water heaters under static conditions (i.e. standing heat losses with no delivery) and using an energy delivery of 37.7 MJ per day (equivalent to a volume of 200 L of water raised in temperature by 45 °C). 2 The values of 37.7 MJ per day, 200 L and 45°C were chosen in order to align with AG 102. 3 For gas heaters, refer to AG 102.
