Apologies, my first post and it's probably been covered many a time before. It's not my first visit though, and I'll give thanks for the info I've taken from this site previously: a god send for the amatuer like me.
Anyway, the heat exchanger in my boiler keeps getting clogged up (with 'gunge' according to BG. Limescale as far as I could tell.)
What type of filter is it I need to fix? I think it goes on the heating return, but someone might correct me if I'm wrong.
Thanks in advance.
