Why steam boilers short-cycle - HeatingHelp.com

2015-8-23 · Every steam system is wide open to the atmosphere. Before each cycle, all the pipes and radiators are completely filled with air because the air vents are wide open. Those vents work in both directions – out and in. The boiler fires and steam forms. It races out of the boiler, shoving the air ahead of itself and toward those air vents.
