## What is an Instant Water Heater?

Unlike traditional tank water heaters, which store a large volume of heated water, instant water heaters, also known as tankless water heaters, heat water on demand. They work by passing cold water through an internal heat exchanger, typically powered by gas or electricity.

As the water flows through the exchanger, it’s instantly heated to your desired temperature, providing continuous hot water as long as the tap is running. This eliminates the need for a bulky tank, saving precious space in your home, and ensures you’ll never run out of hot water.

## The Advantages of Instant Water Heaters: A Hot Brew of Benefits

Instant water heaters offer a host of advantages that make them a compelling choice for homeowners seeking ultimate comfort and efficiency:
