hot water radiant heat

[phillip j shaff]

Our house is heated with a hot water boiler and cast iron radiators. About a month after we used the heat we noticed a quiet sound of rushing water in the highest most radiator in the house. We researched and discovered that we should bleed the radiators periodically which we did. However, only one radiator of 6 had any air, the others flowed a steady stream of water. The problem has now gotten much worse to the point that each radiator sounds like its own waterfall. We cant seem to get any air out of any of them. PLEASE HELP!!!!

Im no expert by any means, but any air in your system is going to want to migrate to the highest zone in your house. As far as bleeding, I was told by a plumber to when you bleed air out of a system, do it sparingly, dont flush a bunch of water as well. The water supply itself has air in it..
