What Is an Electric Tankless Water Heater?​

The main characteristic of electric tankless water heaters is that they do not have storage tanks. The water is heated directly as it moves through the system. What happens is that when a user turns on a hot water tap, cold water from the normal supply travels through a pipe and into the system where it gets heated directly.

The result is that as long as there is energy, there will be a constant supply of hot water in the home.
