Definition from IAI: An IfcElectricHeaterType is a device that emits electrical energy as heat.

> HISTORY: New entity in IFC 2x2

Use Definitions

An IfcElectricHeaterType is a subtype of IfcEnergyConversionDeviceType that provides for various devices that emit electrical energy as heat.

Usage of IfcElectricHeaterType defines the parameters for one or more occurrences of IfcEnergyConversionDevice. Parameters are specified through property sets that are enumerated in the IfcElectricHeaterTypeEnum data type.

Property Set Use Definition:

The property sets relating to the IfcElectricHeaterType are defined by the IfcPropertySet and attached by the IfcRelDefinesByType relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to an IfcElectricHeaterType are part of this IFC release:

- Pset_ElectricalDeviceCommon: property set for properties that are common to all types of electrical devices, if available
- Pset_ElectricHeaterTypeElectricalCableHeater: specific property set for the properties of an electrical cable heater emitting heat along its length, if available
- Pset_ElectricHeaterTypeElectricalMatHeater: specific property set for the properties of an electrical mat heater emitting heat over its complete coverage area, if available
- Pset_ElectricHeaterTypeElectricalPointHeater: specific property set for the properties of an electrical point heater emitting heat at the point of its location, if available

Geometry Use Definitions

Representations of the type are defined as representation maps (at the level of the supertype IfcTypeProduct). These are assigned at the occurrence through the IfcShapeRepresentation.Item being an IfcMappedItem.
