    fired up furnace to test baseboard heating. everything working as it should but , no heated water not getting to floors above though, circulator pump does turn on and the initial sound of water moving is heard, from info read so far, there may be air in the line, there is an expansion tank, how would this air be released any other checks that should be done. thank you in advance.

    boiler not furnace

    Most likely, you need to purge the air out of your heating lines. Usually there is a combination of a ball / gate valve with a boiler drain just above it that you can hook a hose to. You would close the valve, open the boiler drain, and bleed off water into a pail until there is no evidence of air in the line.

    If you have more than one zone, you would close them all, do this procedure to each zone individually, then turn them all back on.

    If this happens each year, you may want to invest in a power vent of some kind - Spiro Vent, Vortex from Taco, Power Vent from Honeywell, Enhanced Air Separator form B&G, Discal from Caleffi . Put one of these devices in and you are not likely to ever have an air problem again.

    If you understand its function, there is a fast fill lever on your boiler feeder. When you start your purge, you can open this lever. This will allow street pressure to enter the boiler system, moving the water around faster scooping up and capturing the air. Just be sure to return the lever back to the normal position each time you close the boiler drain. If you don't, the relief valve on your boiler will blow off, causing you to panic and you'll have some more wet problems to deal with.

    Hope that helps you. It's not hard to do, but every installation is different. Without seeing it, we can only talk in generalities. If your not perfectly clear with this explanation, don't play around. Higher an experienced plumber to do this for your.
