What to do if one radiator is not working?
Make sure there is no air in the radiator. Using a radiator key and a cloth, release any air trapped in the radiator. Remember to top the heating system up with water should it be a pressurised (sealed) system. If the radiator is cold at the bottom it could be sludge in the radiator.
What should I do if my radiator is cold?
If only one of the radiators in the house is cold then it’s a good bet that the problem is isolated to that radiator rather than the central heating system as a whole. This means that you should be able to fix the problem yourself. If it is cold all over, it is worth checking that the valves on both sides of the radiators are open.
Is there a radiator that is both hot and cold?
Discussion in ‘ Plumbing and Central Heating ‘ started by TheRunningMan, 23 Jan 2013 . Hi. All the radiators in my house are hot except for one of them which is cold and both connected pipes are also cold.
Why is my lower radiator hose Cold instead of hot?
If you have a problem with your coolant temperature and realize that the lower radiator hose is cold instead of hot, you could be experiencing problems with the coolant system that needs to get fixed. You will need to look at the various parts that influence the radiator temperature to properly diagnose a lower radiator hose cold problem.
Why is my radiator cold in the loft?
Another cause for loss of heat on just one storey is depletion of water in the feed and expansion cistern. This is usually located in the loft and should be full enough to float the ballcock while leaving room for the water to expand.

When is the top of the radiator supposed to be hot?
Either-way, the top hose gets hot after the thermostat has opened. The time the thermostat takes to open depends upon factors such as: In this post you’ll learn how the coolant system works, when the top hose should get hot and what you should do if it doesn’t. The coolant system after the oil system is the next most critical system.
