Anyone ever have experience with an EEMAX tankless water heater. Looked at one the other day. UL Listed. The heating element is a BARE nichrome coil IN the water stream!! Available in voltages up to 277 single phase and 480/277 three phase as far as I know. Any thoughts about having bare energized conductors in domestic water piping??
jes, There shouldn't really be any problem with this type of system, as long as the whole Hot Water system is Earthed properly. There is also the Electrode-Boiler system, that uses the Electrical resistance of the water itself, to heat the water, this also uses bare, live "elements", in contact with the water. Hope this helps.

Those units (I call them demand units because they just warm the water on demand) are very popular in Puerto Rico and other parts of the carribean where homes don't need heat and don't have hot water tanks as a rule. The most common unit is right in the shower head and cord & plug connected. It's just plugged into the outlet in the bathroom. BTW most of the bathroom outlets I've seen in that region are not GFCI protected. OSHA Professor Grizzy
