DOE capacity is a federal rating, and assumes the boiler is installed in a heated space and that all jacket and piping losses are usable and help offset the heating load. NET IBR rating assumes the boiler is installed in an unheated area, such as an unheated basement or garage, and that all jacket losses and piping losses are wasted. The NET IBR rating is an automatic 15% reduction of the DOE output. • What is “pickup” allowance? IBR includes “pickup” in the 15% output reduction of the DOE output. Pickup allows for the heating up of cold cast-iron boiler sections and cold steel pipe.
