hi, thanks. Pretty sure its the right thing. It gets rid of a load of black muck thats clogging up the boiler. Im trying to avoid fully flushing the system as its gonna cost a bit
well thats very useful isnt it! can anyone actually help please. an engineer did it before and it sorted out the same problem but it needs to be done again
I have been told i need to backflush my boiler as the hot water keeps running hot & cold. Its a Heatline vizo. Can anyone explain how please as i would love a consistantly hot shower??
Many thanks
