The last rad. in line does not get hot
The last rad. in line does not get hot
(OP)
Hi friends,
Im about to visit the site where the last (or few last)radiator(s) in the line does not get hot.
What would typically be the cause of that?
I was thinking of:
Air-lock (upstream)
Undersized pump
Undersized pipework
Short-circuit flow upstream
Is ther anything else that could cause this problem?
PS. If above were one pipe system, would some fault within the radiator be the cause?

RE: The last rad. in line does not get hot
You can test this by shutting a couple of rad valves close to the pump, to see if the end-of-line rads get hot. If this works, you need to balance the complete hot water system.
