Have you tried bleeding it?I have a vertical radiator with 13 columns. It is the furthest radiator from the boiler. When the boiler starts, only the 2-3 columns on the radiator OUTLET side become heated.
Can someone explain why the radiator does not fully heat?
Well, it is certainly worth a try.Riley: Thanks for your feedback.
My gravity-fed system has 19 rads with a Grundfos UPS (obsolete) pump.
My problem rad has never been quick to warm and has failed completely since I drained the system to replace another rad. The rad is fully bled and has no sticking valves.
I take your point about inadequate pump power. so my immediate plan would be to turn off all other rads to see if this forces water to the problem area. I would then go to a long-overdue balancing routine.
Am I on the right track?
