On Demand Water Heater Gas Vs Electric

However hot water temperature and flow again depend on the temperature of incoming water.

On demand water heater gas vs electric.

We rated the annual energy consumption cost excellent for a gas. Thus a gas fueled water heater is the better match for multiple uses in a large family. Electric water heaters typically have a lower upfront cost than gas water heaters. Gas and electric tankless water heaters run more efficiently than the conventional water heaters of the same fuel type.

This energy star certified titan of a tank delivers up to 72 gallons of hot water per hour dependent on tank capacity which is a rate much faster than the normal electric water heater.
