Simple explanations for plumbing problems

Radiator hot at top cold at bottom or cold patches

The first step is to turn off your other radiators at one valve with the heating on.  Wait for 5-10 minutes if the radiator comes on the central heating needs to be balanced.  See the separate page for balancing heating systems.

If the radiator still isn’t coming on it may be dirt and sludge in the system.  Drain off some water from the central heating system.If its black you may need to have it power flushed.
