GB 20665-2006 Minimum allowable values of energy efficiency and energy efficiency grades for domestic gas instantaneous water heater and gas fired heating and hot water combi-boilers (English Version)
Minimum allowable values of energy efficiency and energy efficiency grades for domestic gas instantaneous water heater and gas fired heating and hot water combi-boilers
1 Scope
This standard specifies the minimum allowable values of energy efficiency, evaluating values of energy conservation, energy efficiency grade, test methods and inspection rules of the domestic gas instantaneous water heater ( contain condensing water heater, hereinafter referred to as water heater) and gas fired heating-hot water combi-boilers ( following for short as heating combi-boilers).
This standard is applicable to the water heater and heating combi-boilers which thermal load is no greater than 70 kW.
This standard is not applicable to the fuel gas positive displacement water heater.
The referred fuel gas in this standard is the one specified in GB/T 13611 "Classification of town gas".
