120V for @240V water heater
I have an electric water heater that is not hooked up electrically, it is being used as a hot water storage tank with the hot water being produced by a propane tankless water heater supplying the electric water heater with a pump.
A real Rube Goldberg setup.
Anyways, with propane now more expensive than electricity I am thinking about hooking up the heater to run on electricity, at least temporarily to see if my energy bills go down.
It's a 50 gallon with two 6000 watt elements that run one after another not concurrently. Probably 40' from the panel.
Question is can I use 120V or a much lower AMP 240V and still have it run correctly ? I understand it would of course heat much slower but my wife and I use very little hot water so it shouldn't matter.
What would be the recommended wire and AMP size for 6000 Watts ?
