Connect electric water heater to generatorConnect any 2-wire voltage to ordinary household water heater, and it will heat water.
120V 277V 208V 230V 240V 250V 3-phase non-balanced etc
Do not rewire inside water heater
Connect either voltage wire to either wire on water heater
Do not exceed 30 amps, 4500 watts

|Ordinary electric water
heater can run on any voltage from any direction (excluding volt/amp
ratings below amount needed to heat tank of water, for example typical 12 volt battery will not heat tank of water).
Voltages include single-phase, split phase, and 3-phase residential/commercial voltages with either 50 or 60 Hz.
Install line fuse if wattage exceeds 4500 Watts.
30 amp fuse would be required to prevent wires from overheating, and eliminate fire hazard.
This information does NOT apply to energy-smart electric water heater with box on top of heater, or newer energy smart with electronics, or to hybrid water heaters, or heat pump water heaters with delicate electronic circuitry.
Why it works like this:
Ordinary electric water heater thermostats are mechanical bi-metal switches and respond to tank temperature, and are not operated by electricity.
Ordinary generic elecrtic water heater thermostats switch electricity on-off using mechanical bi-metal switch.
Heat elements are simple coil of thermal wire that gets hot when voltage is applied.
The element will get hot when power is applied.
Cook and stay warm with charcoal briquettes if you have no powerHeat well house or pumphouse with briquettes
Use metal pan, galvanized bucket.
Set bricks in circle on concrete step stone.
Do NOT use gasoline.
Never use gasoline as accelerant.
Use charcoal ligher fluid.
Use newspaper, cardboard, old book to get fire started.
Use WD40.... as last resort... but ONLY small amount on dry briquetts before fire is added... can of WD40 will explode in face.
Smoke will aggrivate asthma
CO2 will be put into air and can cause death if no ventilation
Be damn careful now.
