F24 HEATING; RANGES; VENTILATING
Description
Class F24 covers heating systems, cooking ranges, and ventilation equipment. This includes furnaces, boilers, heat exchangers, space heating devices, cooking appliances, and air circulation/extraction systems for buildings and industrial applications. The classification encompasses both the equipment design and associated control mechanisms for thermal management and air handling in residential, commercial, and industrial settings. Related mechanical engineering aspects such as combustion, heat transfer, and air flow regulation fall within this broad category.
IPC and CPC are identically structured here. All 8 subcodes exist in both systems.
6 shared codes have differing titles between IPC and CPC.
