Re: Hot water heater
I could never understand why someone would heat already hot water.

Re: Hot water heater
That's a lot of watts.

Re: Hot water heater
I don't think I've ever seen a 9000 watt water heater, though.

Re: Hot water heater
Water heaters running on 120-volt power have a long recovery time, which is impractical for most households; 120-volt elements consume 1125 watts, while residential 240-volt heaters use 4,500 watts. If a heater has two elements, people sometimes assume that they should add their wattage to get the total power consumption of the heater. This isn't correct, because both elements don't come on at the same time. A heater with two elements and a label that specifies a power usage of 4,500 watts for each element uses a maximum of 4,500 -- not 9,000 -- watts.

Re: Hot water heater
Another difference often overlooked between 120v and 240v is the wire gauge. Not only does 240v offer the ability of twice the power (watts) on the same gauge wire as 120v at the same amps, but usually the 240v wire is a heavier gauge which allows it to carry even more amps, thus allowing 3 or 4 times the amount of power that a typical 120v circuit can handle.

Re: Hot water heater
Started process of removing old waterheater. PO had wired both hot legs, but clipped off the neutral wire. Ground was clamped to cold water inlet pipe. This can't be right.....

Re: Hot water heater
Here's the neutral wire that fell out of the electrical tape when I started probing the electric feed to my hot water heater. The ground wire was also clamped to a copper water pipe.
