The standard of the energy efficiency labelling grade 1 for an electric hot and cold water dispenser was strengthened by approximately 20% since 2018.
The energy efficiency level index for an electric hot and cold water dispenser should not exceed 0.8. The energy efficiency level index is defined as the power consumption with no water discharge for 24 hours divided by the power consumption of the insulation performance for 14 hours.
