An instant water heater, or tankless water heater, is a device used to instantly heat cold water through gas or electrical heating unit. It consists of a hot water outlet, flue pipe, draft divider, pressure relief valves, dip tubes and tanks.

The heated water is utilized for various purposes, such as cleaning, washing clothes, dishwashers, hot water showers, cooking, removing stains and relieving clogged drains. In comparison to traditional water heaters, instant water heaters are easy to install, cost-effective, convenient, compact and energy efficient. They also heat faster through a small-sized heating chamber.
