I have just had two valves replaced on one of my rads. The guy started by shutting off all the valves on the other radiators(11).
He shut the tap that fills the tank which fills the radiators and then drained the radiators.
Once the new valves were fitted he re-filled the system and bled all the radiators. He said that it would take a few hours for all the rads to get hot but four hrs+ and still only a few of the radiators are warm.
My boiler seems to fire for a short time then stops. The radiators upstairs felt quite warm at the top but cooler at the bottom. The rad with the new valves is still stone cold and is upstairs. Some rads downstairs did get warm some time ago but are cold now.
I have the thermostat turned up to max and can hear the pump running upstairs in the airing cupboard. The cool ones have their valves open and have tried bleeding them again but no joy.
PLEASE HELP!! Thanks.
