Hi all,
I removed a radiator to do some diy and had a problem with the TRV, as a result my CH system lost a few bowls of water.
I have now refitted the rad but my Worsester-Bosch Greenstar 42 CDI is showing zero pressure.
Will it take some time for the pressure to build? Or do i need to repressurise my system. There's no water tank in the loft so i presume i have sealed system and need to open a tap to refill it. Does anyone know where this is located on this boiler.
Thanks all, Bob
