Hi Colin. If you are in doubt of the quality of particular water heater brand made in China I would think you might look for decent isolation transformer of appropriate power rating and would connect the electrical water heater through it. Don't forget to have a fuse in secondary in case if heater will decide to short circuit in addition. :) WBR Dmitriy. cdb wrote: >=20 > I'm back on my hobby horse concerning electric shower units (tankless > heaters).
