I have 14 year old GEM combi-dont laugh-its in good shape except DHW supply on off etc-cause (BGH) scaling of secondary heatex-
BGH will descale using sonic method but I can have it descaled using chemicals-its taken out and put in a chemical bath-BUT it may leak-drip when refitted -What should I do -is chem cleaning worth the risk?-
Are any spare parts available; and could another calorifier be fitted -different make of course-as a replacement
Please dont say scrap it-cheers!
