Forced Hot Water Heating System

I would like instructions on how-to remove air from my hot water based board heating system. I have 4 zones, one being my hot tank. I believe purging the system is a term used. Could you provide me with some detailed instructions?

I've got issues with the same type of thing

I recently moved into a house with the same type of heating system. I personally don't find it too good, as the house is perpetually cold.

In any case, my roommate turned a valve on one of the vents, and water was trickling out. I don't think this is a good thing, but it could also be a result of the system not being taken care of in a few years.

Any advice would be greatly appreciated!

The thermostat is responsible for temp control. What are you setting it at? It may be out of calibration and needs to be set a little higher. The water leak is a different story. What kind of valve was it? If it was a radiator valve, there may be a nut under the handle that can be tightened SLIGHTLY to stop the leak. If not, you will probably need a tech to repair it.

The thermostat is set to 90 degrees.

As for the valve, he'd said something about releasing air, but after seeing the water, I don't know that we have the same type of system he was thinking of.

bleeding

Bleed the lines by unscrewing the screws at the end of the lines until water trickles out. Then retighten. Purging is when you flush out the furnace, I think. All in all you must find out if you have water circulating or not. and why. that would be the circulator pump Mr. do-it-yourselfer.

Upper floors? Could be a number of things, but let's start with you having a look at the pressure gauge on the boiler. Tell us both the pressure and temperature reading on that gauge.

We will probably be asking for you to take some pics and upload them to a photo hosting site such as Image hosting, free photo sharing & video sharing at Photobucket (free account) and place a link here so we can view your pics.

If we can't see your system, we can't tell you which valves to mess with... you need to post some pictures.
