Hi all,
1 of my 6 radiant heating zones has decided to occasionally start banging. This occurs only when heating and can be felt in the copper pipes leading to where this zone disappears into the floor. Other zones are fine. Have also noticed that water circulation is also affected in this zone and will sometimes stop heating (pipes from boiler are warm and ones leading back to boiler are cool while circulation pump is on.) The banging will stop if I turn down the thermostat to stop the circulation pump. I can turn it back on 5 minutes later and it might not come back for a day. The circulation stopping is something I've just noticed. Now, would air in the zone cause these these two problems (banging and stopping of circulation) to occur so intermittently? Pressure is about 14 lbs on the gauge on backup oil burner and 13 on the Tarm.
Thanks,
Roger
