Most hydronic heating boilers short-cycle. This creates mechanical problems and wastes energy. Surprisingly, most of this short-cycling is designed into modern systems. Numerous customers, including many engineers and contractors, have come to us looking for a deeper understanding of the phenomenon and for a definitive solution. This paper addresses these concerns, develops theory, and presents a bullet-proof solution to the short-cycling problem. The paper is presented in three parts.
