F24V COLLECTION, PRODUCTION OR USE OF HEAT NOT OTHERWISE PROVIDED FOR
Introduced: January 2018
Description
F24V covers heat collection, production, and utilization applications that do not fall under more specific heating classifications within F24. This subclass encompasses residual heat recovery from industrial processes, waste heat utilization systems, and unconventional heat generation methods not covered by dedicated F24 groups for combustion heating, electric heating, or heat pumps. It typically includes technologies for capturing and repurposing thermal energy from exhaust streams, thermal storage systems designed for heat management, and composite heating arrangements combining multiple heat sources. The scope excludes mainstream heating systems already classified in F24B–F24T and focuses on supplementary or innovative heat-related technologies requiring dedicated patent classification.
IPC and CPC are identically structured here. All 4 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 2018.
