Comprehensive Performance Testing Equipment for Gas Wall-Hung Boilers (Laboratory Use) WH-CL02-800C

1. Introduction to Wall-Mounted Boiler Comprehensive Performance Testing Equipment

The comprehensive performance testing equipment standards for this wall-mounted boiler are being developed using the standards "GB6932-2015 Household Gas Rapid Water Heater," "GB25034-2010 Gas Heating Water Boiler," "CJ/T395-2012 Condensing Gas Heating Bath Dual-Use Boiler," "CJ/T336-2010 Condensing Household Gas Rapid Water Heater," and the energy efficiency standard "GB2665-2015 Energy Efficiency Limits and Grades for Household Gas Rapid Water Heaters and Gas Heating Stoves." It mainly measures the heat load and energy efficiency rating of gas wall-hung boilers, suitable for R&D testing with water heater and wall-mounted boiler manufacturers, as well as inspection tests. Quality inspection units conduct conformity evaluation of the product.
