When your boiler keeps shutting off and restarting, your first instinct might be to replace parts—but that's not always the problem. In this Weekly Boiler Tip, WARE explains one of the most common causes of boiler short cycling: improperly coordinated firing rate and operating pressure controls. Learn how your modulation settings affect burner operation, why your boiler may never reach low fire before shutting off, and how a simple control adjustment could improve efficiency while reducing wear and tear. Safety notice: Always consult experts for complex repairs. Weekly Boiler Tips are compiled by the knowledgeable and remarkably prolific content creators at WARE, a family owned, third-generation, 69-year-old commercial and industrial boiler rental and service firm based in Louisville KY. You can learn all about this and more at WARE's Boiler University.
