Sorry Mike. I'd not be feeding the earth to consumer units or radiators, your negating the effect of a separate earth. I know all the reasons mentioned above but it's totally pointless if you want to reduce the effects of noise from SMPS Etcetera. Mike, give the tranny a whirl I think you'll be impressed, it's the best method to gain the best from your earth rods.
