Teledyne-Lars Boiler Hammering
Posted by Fred Pfeiffer on November 30, 1998 at 13:34:05:
Hi, Two years ago I had a Teledyne-Lars boiler installed in our home. Our home is a three level home with three seperate zones. Ever since the furnace was installed during the winter it causes the pipes to hammer just as the boiler is shutting off. We also hear a noise occasionally that sounds like a Cessna plane overhead that lasts for several minutes. The installer has thrown up his hands, he has backed off the pressure in one zone and I continue to get air out of the four release valves near the boiler. My wife is a light sleeper and this keeps her awake. Help! Any ideas?
