Recently I came across this ad for an electric shower head heater. It is a "Coral" brand. www.execelonlinestore.com under elecric appliances . I bought one thinking maybe it could be used as an outdoor water heater in a camping situation. Maybe could be used as an inline "tankless heater". $39.95 - not much at risk.
When I received it the directions indicated the cutoff valve must be upstream which would rule out an inline "tankless heater". It only turns on when you open the valve(has a diaphram operated connection when pressurized). My need to know dictated that I disassemble it to see what makes it tick. When I got to the inerds I discovered a coil of resistance wire around a plastic form much like some space heaters I have seen. But the water just circulates around the coils. There is a "ground" wire which is fastened to a screw and nut which the water would be exposed to.
My question is "why would this not shock the user"?? There would be 110 volts or 220 volts, (depending on which one you buy) with the water running across the coils and then upon your body.
The connection is two wires which the directions say the polarity is not important.
