How can i clean out a heat exchanger on a Halstead Best 80 boiler. Do i need to try and flush it out or can i remove it and clean it? Any advice appreciated
Hi all.
Hope someone can help. Central heating wouldn't work so drained system. Went to header tank to put inhibitor in and found tank still full. Found blockage between header tank and pump. Cleared blockage but now system fills up but boiler cuts off after 3 to 5 mins so rads dont get hot...
