[QUOTE="drlabman, post: 1158852, member: 419880"] Thanks for that. Not sure I fully understand but let's start with this ... Ground on the satellite system - as far as I know, it's only the TV that has a dedicated ground. The Humax box power is supplied by an external adapter - DC or AC? not sure - but does that ground the Humax? The boiler is gas fired. I don't think the pump is involved in hot water delivery because it's at mains pressure. The TV, Humax and boiler are all on the same ring main. Does that answer some of your questions? Update: from what I can tell the power adapter for the Humax supplies 12V DC and there's no ground PIN (it's plastic) - so the ground for the whole system is supplied by the TV only? Am I missing something? [/QUOTE]
