What is a tankless water heater and how does it work?
Tankless water heaters heat water instantaneously without the use of a storage tank. When a hot water faucet is turned on, cold water flows through a heat exchanger in the unit, and either a natural gas burner or an electric element heats the water.
Is a tankless water heater worth the cost?
Energy Use and Efficiency Tankless: Gas and electric tankless water heaters run more efficiently than the conventional water heaters of the same fuel type. We rated the annual energy consumption cost Excellent for a gas model but only Fair for an electric, but both rate Very Good for energy efficiency.
Why is tankless water heater installation so expensive?
