: I have an older home with hot water baseboard heat. Two of my four upstairs units do not get hot. I have water at the units, but no hot water curculating through them. Ive bleed the air from both many, many times with no results; I only get cold water? Ive even given some thought to putting a small circ pump in the lines feeding them??? Has anyone tried this?? Help??? As a masterplumber, I would suggest that you consider the root of the problem….maybe its a design problem. Maybe there are some other plumbers here that would like to comment also.
