Hi all,New to this so bare with me.recently my digital went blank.replaced batteries and it came back to life!! Hot water but no heating still.I've read that the system has to be recommissioned before heating will return but not being able to find any instructions on how to do this I contacted a local plumber who came to the house and diagnosed a new pump and chemical flushing of the system.can anyone help as I don't want to be stitched up for unnecessary work.
