Why is my radiator half cold?
Radiators need bleeding when they have air trapped inside them. This trapped air stops warm water circulating around your radiator. That can make the radiator cold at the top, but warm at the bottom. It means your central heating system isn’t working efficiently and it can take longer to warm up your room.
Why is only top of radiator hot and bottom cold?
A radiator which is cold at the top but hot at the bottom suggests that air is trapped in the system. To bleed the radiators you’ll need a radiator key and a dry cloth. You’ll need to turn the heating off, allow it to cool and release the open the bleed valve by turning the key.
Why would a radiator be cold at the bottom and hot at the top?
If your radiators are cold at the bottom but hot at the top, this can only mean that the flow of hot water is somehow being restricted or redirected so it’s not reaching the whole of the radiator. If several channels are blocked, the whole of the bottom part of the radiator will not be getting any hot water.
Why is my radiator not very warm?
If just one (or a few) of your radiators aren’t heating up, the most common reason for this is trapped air.

Your radiator should soon be nice and warm.
