This 13 year old Worcester CDI Classic needed a lot of attention!! The original problem was hot water running hot and cold which is a sure sign the plate heat exchanger needed descaling/flushing through which worked a treat! After that it failed its flue gas combustion analysis and that resulted in it needing a new gas valve. Worcester Bosch are a nightmare to work on but not impossible. This one is running efficiently again 👍🏻😍 | Farmore Heating
