Why are half of my radiators cold?
When a radiator appears to be cold at the top but still warm at the bottom, the usual culprit is air trapped in the heating system. There is a very simple approach to fixing this, which is to bleed the radiator. Bleeding a radiator releases the trapped air, allowing your radiator to run more efficiently.
Do radiators have two valves?
The two radiator valves on a radiator work in the same way as taps, affording the user control over the level of heat they emit. The other valve, referred to as the lockshield valve, balances the system by regulating how much heat the radiator gives off.
Should both radiator valves be fully open?
Most lockshield valves have a plastic or metal cover. You should remove these and open all of the lockshield valves completely. This requires that you turn them anticlockwise. You should also fully open the TRVs (thermostatic radiator valves).
How do you replace both radiator valves?
- Switch off heating system and shut off water.
- Locate the drain off.
- Remove the old radiator valve.
- Fit the new radiator valve.
- Turn the mains water back on.
- Bleed the radiator.
