Should I main bond?

[MikeJ42]

Hello,
I have a standalone solid fuel boiler (giant cast hunk of steel that sits directly on the concrete in the kitchen) that feeds my rads. Should the water pipes be main bonded back to the CU? There is a stainless chimney that goes outside at headhight, and this will be at the same potential if I bond the pipes. Any thoughts?
Many thanks,
Mike.

No need to bond as the boiler will not be introducing a potential from outside.If this boiler were fed from gas/oil from outside then this would require a Main Equipotential Bond.
