A 240 volt heater can be run off of 120 volts but the wattage will be reduced.For example if an ordinary 1000 watt baseboard heater's supply is 120 volts, the current of the heater will be, I = W...

For a heater that's rated at 240V, you'll want to flip your logic around -- it starts off as a 240V 5A (to use your example's numbers) heater, but the transformer makes it pull 10A @ 120V. – ThreePhaseEel Nov 16 '18 at 12:36

You can switch back and run the electric water heater on 120V during the peak hours to reduce the electric bill or less hot water is needed. Keep in mind that the same power rating water heater can be operate on both 120V or 240V AC. As we know that the same water heater rated for 240V can be operated on 120V.

A 240 Volt heater run at 120 Volt will produce 25% of the rated wattage. A 120 Volt heater run at 240 Volt will be 4x 120 Volt rated wattage destroying the heater destroyed and poses a severe fire hazard. What voltage are my heaters?

Ohm’s Law Kicks In. Yes, you can wire a 240-volt rated water heater with 120-volts, exchanging the second hot (red) wire for a white (neutral) wire to the neutral bus. Strange, but true. Because of Ohm’s Law and the fact that the resistance of the circuit stays the same, half the voltage means the watts of heating energy generated is reduced to one ...

Connecting either hot wire and the neutral provides 120V. This is how most modern US homes are wired. The 240V is used only for high wattage appliances like clothes dryers or water heaters. If the Appliance have two hot, neutral and ground you will need a transformer that input 1P 240V and have an output 120V-0-120V for it to work.
