I don't know about copper bits and elements, I couldn't get a clear answer from a sparkie so I changed to the marbles just to be on the safe side. I think that the internal elements create a sufficient surface area for bubble formation so the marbles/chips are probably unnecessary but I still like using them. :handgestures-thumbupleft:
I like the glass marble idea Kiwi :handgestures-thumbupleft: I reckon i might run with that. Are you talking run of the mill kids marbles, or something different?
My reason for having them in the boiler was for no other reason than they sound cool.
And now i can add that they aid against surge boiling :-B
Appreciate your input all.
Thankyou
