What is a Water Heater?

A Water Heater is an appliance designed to provide a steady supply of heated water for residential or commercial use. It ensures that water is available at the right temperature for bathing, cooking, cleaning, and other everyday needs. By heating and storing water in a tank—or heating it on demand—water heaters make modern living more convenient and efficient.
