HI Steve,
       If this hot water system has an insulated flange anywhere in it, or
there is an insulated flange between the cold water supply to the heater, the
your coil will make it into a large antenna, possibly at lethal voltages.
Anyone touching the heating system anywhere in the building could get zapped.
