Basic Information
Scope
Scope: This document specifies the normative reference documents, terms and definitions, basic requirements, evaluation indicators and requirements, and evaluation principles and methods for the evaluation of "innovative models" of gas heating water heaters. This document applies to heating boilers with a rated heat load of less than 100kW, a maximum heating working water pressure of no more than 0.6MPa, and a working water temperature of no more than 95℃, which use atmospheric or fully premixed combustion, including: a) Type 1P and Type 1G forced air-supply and exhaust heating boilers in Appendix A of GB 25034-2020; b) Type 9P and Type 9G forced air-supply and exhaust fully premixed condensing boilers with a heat load of more than 70kW in Appendix A of GB 25034-2020; c) Type 10Z, Type 10P, and Type 10G outdoor heating boilers in Appendix A of GB 25034-2020.
