class Ifc4::IfcSpaceHeater : public Ifc4::IfcFlowTerminal

Space heaters utilize a combination of radiation and/or natural convection using a heating source such as electricity, steam or hot water to heat a limited space or area. Examples of space heaters include radiators, convectors, baseboard and finned-tube heaters. IfcUnitaryEquipment should be used for packaged units supporting a combination of heating, cooling, and/or dehumidification; IfcCoil should be used for coil-based floor heating.

HISTORY New entity in IFC2x4

Type Use Definition IfcSpaceHeater defines the occurrence of any space heater; common information about space heater types is handled by IfcSpaceHeaterType. The IfcSpaceHeaterType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcSpaceHeaterType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcSpaceHeaterType has ports or aggregated elements, such objects are reflected at the IfcSpaceHeater occurrence using the IfcRelDefinesByObject relationship.

Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcSpaceHeaterType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcSpaceHeaterType.HasPropertySets. If both are given, then the properties directly defined at IfcSpaceHeater override the properties defined at IfcSpaceHeaterType. Refer to the documentation at the supertype IfcFlowTerminal and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: (All Types)



Pset_SpaceHeaterTypeConvector (PSET_TYPEDRIVENOVERRIDE)


Pset_SpaceHeaterTypeRadiator (PSET_TYPEDRIVENOVERRIDE)

Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.


Material Use Definition The material of the IfcSpaceHeater is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcSpaceHeaterType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:

Body: The primary material from which the object is constructed.

Port Use Definition The distribution ports relating to the IfcSpaceHeater are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the space heater occurrence is defined by IfcSpaceHeaterType, then the port occurrences must reflect those defined at the IfcSpaceHeaterType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcSpaceHeater PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:


Power (ELECTRICAL, SINK): Receives electrical power.


Inlet (HEATING, SINK): Water or steam supply. Outlet (HEATING, SOURCE): Water or steam return.
