Major air pocket!

Whats the pressure in the system ? You could be draining and not adding any water. Two story house, you should be between 15/18 lbs.

Air lock

I have 2 circulators drawing down from 40 baseboards.. Is it possible its creating an airblockage in my lines. I have one side of the floor thats not getting heat. They stay hot for 1/2 then never get hot again unless i draw water out. This is a water system. Any input would really be appreciated . Thanks

If the circs are on the returns

you could definitely have an air pocket, and the circs would enlarge it every time they start up. Pump Away and that should cure it- unless the problem is not an air pocket......
