Everything You Need to Know About Tankless Water Heaters

A tankless water heater, also known as an on-demand water heater, heats water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit, where it is heated by either an electric element or gas burner.

Unlike conventional tank heaters that constantly maintain a reservoir of hot water (wasting energy in the process), tankless systems only activate when you need hot water — delivering it instantaneously and endlessly.

This on-demand approach eliminates standby energy losses and can reduce water heating costs by 24-34% for homes that use 41 gallons or less of hot water daily.
