basement radiator

If the rad has been bled and no air came out, I would purge that line. You may be air bound at the highest point where the pipes branch off to service that rad. I installed bleeder 90's on my downstairs rad and can now bleed that high point out without purging. Air will sit in the highest point of those runs.

basement radiator


Hello,
I have an old gravity upfeed system, and in the basement, where the furnace (boiler? i can never remember the difference) is there is also a radiator. this radiator is the lowest point in the system which is why I am guessing it never gets hot. the valve is open all the way and no air bleeds out- but the radiator never gets hot even though the supply pipe gets really hot sometimes. anyone have any guesses as to what i could do about this? I just finished renovating the basement into living space and now realize it does not get warm enough.

On another note; the expansion tank in the basement has to be drained at least 2 times per season, i don't know if that has anything to do with a problem in the system as a whole.

Thank You!

Expansion tank

If the expansion tank has a gage glass on it, the top gland may have a slight leak. Or maybe the water in the tank is just absorbing air over time. It is not unusual to have to occasionally drain tanks that have no bladder.

In a gravity hot water system, a radiator in the basement must have a a return line from the bottom of the radiator to the boiler. Sometimes these are undergorund. The line may be plugged of collapsed. Or perhaps the valve is just not opening. Of course there is no air vent. Air goes up, not down.
