Air in a residential hydronic system is normal. Or so, that's what many believe. Truth be told, air doesn't need to be a problem. For more than a decade, Spirotherm Inc. has worked with innovative contractors and the top wholesalers to provide customers with air-free hydronic systems.
Take it from John Javorka, a Chicago resident, who had ongoing air problems in his heating system for twelve years before he tried the Spirovent. He tried several different methods of purging air from the system - methods recommended to him by a couple of experienced boiler servicemen. He changed packing nuts on the gate valves, and when that didn't work, changed the gate valves as well. Didn't work.
