My sparkys queried whether a wallstar oil boiler requires equipotential bonding outside, considering the copper supply pipe from the tank connected to the non-return valve / fire valve then connects to a clear plastic hose before it goes to the pump/burner etc. The fire valve is held in place with a clamp connected to the boiler case, which I guess is also connected to a part of the case which is inside the home - so does it need cross-bonding outside???

I think the wisdom i received from the group when I asked this some time back was that if the oil pipe didn't enter the house, then the circulating pipes should be bonded as near to the boilder as possible.
Being as my system is all tied together with copper pipe which has been soldered together, i'm not loosing any sleep over the fact that i've not yet obtained a round tuit for this particular job yet.
Great boiler BTW (unless you're outside in the rain servicing it, or having problems persuading repair men to do same :=))
