Customer Question

Hi, Three of the radiators in our house are cold. They are the bathroom towel rail (which is heated and has not worked since being fitted), the small radiator in our lounge and the small radiator in the main bedroom (on the same side as the one in the lounge). I have bled them and also checked the header tank (which is full) and none of this has made any difference. Any suggestions?

When you bleed the radiators make sure the pump is off and you get water out of the radiator.
Let me know if the radiators have thermostats on?

Did you manage to get this sorted - do you still require help?

Have not tried bleeding yet. Though have noticed that the pipes to the radiators involved are cold

Ok, try balancing the system.
Turn off the hot water and just turn on the heating.
Open all your TRV's to max if you have them fitted.
Close all your radiators valves and open them 1/4 turn.
Run your heating for 10 minutes
Any rads that are not warming then turn them up another 1/4 turn.
Keep repeating until all your rads are warming, then adjust your TRV's back to their settings.

Your system should now be balanced.
