OR-16-C012 -- A Deeper Look at Modern Heating System Design

The heating, ventilation, air conditioning, and refrigeration industry shows a trend toward increased adoption of condensing boilers in heating systems, butthe full impact on design and construction is complex. In design the selection of the boilers, heating coils, and operating temperatures play equallyimportant roles in the composition of an efficient system. The failure to optimize design for a system as a whole can lead to wasted energy and money. Thispaper investigates the effect on overall system performance and construction cost of various heating system metrics with regards to condensing and noncondensingboilers.
