    Bleeding

    Bleeding or purging of air. Need a few details here Art. Do you have vents/bleeders on your Rads or baseboards?(Y/N) Down in the boiler room, look at the pumps most are on the return pipe that pipe should enter the boiler low down toward the base.
    Looking at the pumps (circulators)do you have valves above them (Y/N) if so above the valves should be Drains or hose connections. Let us know what you have and we will tell you how to purge your heating system. Best Wishes J.Lockard
