Description
F24H encompasses fluid heating systems that generate heat through active means such as heat pumps, combustion, or electrical resistance to warm water, air, or other fluids for space heating, domestic hot water, and industrial applications. The subclass covers the overall design, integration, and operation of heater units combining heat sources with heat transfer mechanisms, including heat distribution networks and control systems. This classification excludes specific combustion chamber designs (covered in F23), dedicated heat exchanger elements (F28), and refrigeration cycles when classified outside heating contexts (F25). Related heating technologies employing passive solar collection or waste heat recovery are separately classified in their respective technology areas.
