Why are my new radiators not getting hot?

Why are my radiators cold when the heating is on?
Why is one radiator cold when the heating is on? One cold radiator usually indicates that either there is air in the system or there is a stuck valve within that radiator. The thermostatic radiator valve (TRV), like the one pictured below, controls the flow of hot water to the radiator.
Why is my heating not working but I have hot water?
If you’ve got hot water, but no central heating then there are more issues it could be if it’s not the thermostat or the boiler pressure. Common reasons for this particular fault are broken diaphragms and airlocks, or a motorised valve failing.

Baird warns that letting out too much water is likely to introduce fresh water into the system, which can make the situation worse as fresh water contains a lot of air. He adds: “Some people also think if a radiator is cold on the bottom but hot at the top then it needs to be bled.

Why do I have to keep bleeding my radiators?
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.
How does air get trapped in radiator?
Air tends to get trapped in your radiators over time through small leaks, especially if you find yourself re-pressurising your boiler often. Or for older systems, you may find air came in through the pump above the supply pipe during installation or through the tank in your loft.
