How do Tankless Water Heaters Work?

Tankless water heaters, also known as on-demand water heaters, work by heating water directly as it flows through the unit. Unlike traditional water heaters that store and heat a large volume of water in a tank, tankless models eliminate the need for a storage tank altogether.

When a hot water tap is turned on, cold water enters the tankless unit and is rapidly heated by electric coils or a gas burner. The heated water then flows out of the unit and through the plumbing system, delivering hot water on demand. Once the tap is turned off, the tankless water heater shuts off, saving energy and eliminating standby heat loss.

The key advantage of tankless water heaters is their ability to provide a continuous supply of hot water, without the limitations of a storage tank. This makes them ideal for households with high hot water demand or large families. Additionally, tankless models are compact in size, allowing for flexible installation options and saving valuable space in your home. Overall, the technology behind tankless water heaters offers several benefits that make them worth considering for homeowners.
