How Many Volts Does A Water Heater Use

Virtually tank-type h2o heaters change from 120-volts to 240-volts at effectually the twenty-gallon size. Simply there are some exceptions both sides of that line, so yous should check the information plate on the side of the tank, like the example above. There is also the further complexity that it is possible, although not recommended, to wire a 240-volt-rated water heater to a 120-volt excursion. It will just produce a quarter of the heat output, then recovery time is boring, merely we have seen a few of them over the years.

For this reason, nosotros also recommend checking the electric panel to determine whether one or 2 slots are used for the water heater. Double breaker, like below, means 240 volts.
