How Do Tankless Water Heaters Work?

Tankless water heaters, also known as on-demand water heaters or instantaneous water heaters, are innovative appliances designed to provide hot water as needed WITHOUT the use of a storage tank. Unlike traditional water heaters, which continuously heat and store water in a large tank, tankless water heaters heat water only when there is a demand for it, such as when a faucet is turned on or an appliance requiring hot water is activated.
