What the notification says

This document specifies the energy efficiency technical requirements and test methods for domestic gas instantaneous water heaters (including condensing domestic gas instantaneous water heaters) and gas-fired heating and hot water combi-boilers (including condensing gas-fired heating and bathing dual-purpose boilers), as well as the calculation methods for annual energy consumption and annual CO₂emission. This document applies to products primarily using gas as the main energy source: a) water heaters with a rated thermal load not exceeding 70 kW, using atmospheric or fully premixed combustion; b) boilers with a rated thermal load of less than 100 kW, a maximum working water pressure not exceeding 0.6 MPa, a working water temperature not exceeding 95℃, and using atmospheric or fully premixed combustion. This document does not apply to gas storage water heaters.
