cold water coming out of 2nd-floor radiator..help.

Hi...I have 3 radiators on the 2nd floor (oil boiler). All bleed cold water. The 2nd floor is a separate zone. When I turn up the heat, the circulator runs and coughs very loudly and no heat or hot water to the radiators. I suspect it's trapped air, but when I bleed the 3 radiators there is no air. just cold water that drips out. The pressure is 22 PSI. Any ideas/help appreciated.

The first floor radiators work fine and the house's hot water works fine. This is an isolated problem. Thank you for your help.

Verify that your gauge is functioning accurately. See this sticky: http://www.doityourself.com/forum/bo...ure-gauge.html

What type of radiators do you have?

Huh? Is it a 'productive' cough? ... ooops, this isn't the medical forum, is it?

You mean that it sounds like air bubbles going through?

What is the make/model of the circ?

The pressure is 22 PSI.
At what TEMPERATURE? What is the pressure when the boiler is below 100F ?

just cold water that drips out.
If the water is indeed just 'dripping' out, you don't have enough pressure in the system. Follow Droo's advice to read the sticky and do that first, before chasing Casper around the boiler room.

Thanks everyone.

1. Downstairs I have baseboard radiators. They work fine and are in their own zone.

2. Upstairs I have 3 old radiators (not baseboard).

3. I double checked the pressure gauge and it works fine.

4. Not sure if this helps, but when I go and turn up the temp on the problem zone thermostat, the circulator goes crazy..starts banging and working hard.

5. I'm sorry for writing the water drips out. It's a nice stream on all 3 radiators upstairs and the water is frigid.

Any ideas greatly appreciated! Thank you for taking your time to help me.

Tough one dunlar.
My guess is there must be air trapped somewhere. but
OR.. Does each zone have its own circulaor?
Possible the circualator is toast.

Almost time for a full course of pictures.

How did you double check it? How do you know it's accurate?

I think it IS time. We'll be looking to see if you have what we call 'purge stations', so get pics of the piping into and out of the boiler.

IN FOCUS, WELL LIGHTED and LARGE enough to see details. FREE account at Image hosting, free photo sharing & video sharing at Photobucket, upload pics there, come back here with a link to your PUBLIC album.

here are photos of the boiler and its pipes. please let me know if you need anything else. I checked the pressure manually as you told me to.

I greatly appreciate you taking the time to help me.

Hello dunlar,
We need more pictures from many different angles.
Follow the pipes everywhere.

Correct that there is only one pump?

Correct.

One pump.

I added some more photos and even uploaded a short video, which I hope makes things easier.

Thank you for taking the time to help me.

For some reason, the video won't play in my browser... might not have the right codec...

Still need more pics... pretend that you are one of us, coming in to look at your system... what would we look at? everything!

Show us all the pipes coming to and from the boiler, every valve, etc...

In particular, the pipes coming to and from the upstairs zone, any valves, etc... and if possible, caption the photos so we know what we're looking at.

Try to get a little more light if possible.

The pressure is 22 PSI.
At what TEMPERATURE? What is the pressure when the boiler is below 100F ?
If you have a three story home, you might need at least 17 PSI when the boiler is COLD.

It's important that we know the TEMPERATURE at which a PRESSURE is quoted.

I finally got it to play in RealPlayer... don't know why FireFaux won't play it...

Still don't tell us much. Watching that video was like peeking through a cracked open door!
