A commercial electric water heater is a type of water heating system that uses electricity to heat water for commercial use. This type of water heater typically consists of an insulated tank, one or more heating elements, and a thermostat. The heating elements use electricity to heat the water, which is then stored in the insulated tank. The thermostat controls the temperature of the water and turns the heating elements on and off as needed to maintain the desired temperature.

Commercial electric water heaters are widely used in commercial settings such as hotels, hospitals, and industrial facilities, where large amounts of hot water are required. They are typically more powerful and have a larger storage capacity than residential electric water heaters. They also have a higher recovery rate, meaning they can heat up more water in a shorter amount of time.
