Do electric water heaters require 220?

Yes, most electric water heaters require a 220-volt electrical supply. This higher voltage is necessary to provide the power needed to heat the water efficiently. However, the specific voltage requirement can vary depending on the model and capacity of the water heater. Some smaller or specialized electric water heaters may operate on lower voltages, but the standard for most residential electric water heaters is 220 volts. It’s important to consult the manufacturer’s specifications or consult with a qualified electrician to ensure proper electrical requirements are met during installation.
