Non working radiators
Posted by Edward on October 16, 19100 at 12:17:57:
I recently "T"d a monologue hot water system, with one thermostat underneath my home. The original feed T's off one Line feeds 3 downstairs radiators and returns through a T to the existing return from the upstairs before the circulator. The new line off the original feed line T's and feeds 4 radiators upstairs and returns T'd with the downstairs return before circulator.

Two radiators in the system are not getting hot water.
Downstairs its the second of the 3. when blead at the return side cold water comes out and eventually it gets hot, but the flow does not continue it returns to cold when the bleader is closed.
Upstairs it is the last of the four radiators that does not heat up.
