IfcHydronicHeater

IfcHydronicHeater

Definition from IAI: An IfcHydronicHeater is a device which adds heat to a space utilizing a combination of radiation and natural convection. The heat source is typically steam or hot water. Examples of HydronicHeaters include radiators, convectors, baseboard and finned-tube heaters, etc. The physical dimensions and properties of the heating element can be defined by an aggregated coil element (IfcCoil).

HISTORY: New entity in IFC R2x.
