Upstairs zone

tr318January 25, 2009

A friend of mine is having a problem with getting heat to her upstiars. She has a forced hot water system with two zones. Recently her father helped her moved the copper pipe going upstairs through her kitchen, he was not able to get the heat upstairs after doing this. I went over and tried purging the stysem with a hose attached to a spicket that is located right after the circulator. I was able to get the hot water into the line at the boiler but still had not hot water circulating upstairs. Anyone help me?

Yes you have air. First what is the pressure, 12 lbs cold approx 15-18 lbs hot 180degrees, If the first floor is working thats great. Is the zone valve opening for the second floor, if it is, shut off the first floor zone. Sounds like you have 1 pump and 2 zone valves. Purge water through the second floor. If your pump is on the return side of the boiler,shut the valve between the pump and boiler, now purge the second floor line making sure the zone valve is open and keep checking your pressure. Make sure your not using the boiler drain.

Thanks bstarz, The pressure is right, there is only one pump, and yes the zone valve is opening. I will purge the system like you said. Thanks again.
