On Demand Water Heater Gas Vs Electric

Gas heaters can have a higher capacity gas water heaters can have a much higher capacity than electric heaters.

On demand water heater gas vs electric.

On the other hand gas tankless water heaters generally have an energy factor of less than 85. Usually an electric water heater supply 5 gallons of hot water per minute whereas a gas tankless can supply up to 8 gallons per minute. However hot water temperature and flow again depend on the temperature of incoming water. Average input ratings for a gas water heater range from around 30 000 to 180 000 btus depending on size.

An electric hot water heater ranges in costs from about 300 to 700 while a gas heater ranges from 400 to 800. Installation costs for an electric heater are 700 to 1 000 while the cost to install a gas heater ranges from 1 000 to 2 000 depending on whether you have an existing gas line and vent. Electric tankless water heaters are extremely energy efficient with more than 98 of energy supplied to the units actually be used to heat the water. They can be 8 14 more energy efficient for homes that use a lot of hot water around 86 gallons per day.

Gas and electric tankless water heaters run more efficiently than the conventional water heaters of the same fuel type. For homes that use 41 gallons or less of hot water daily demand water heaters can be 24 34 more energy efficient than conventional storage tank water heaters. The more btus the faster the unit will heat water. Most gas heaters provide you with at least 8 gallons of hot water per minute expressed as 8 gpm.

Electric water heaters range in power. Gas water heaters of all types also contribute to greenhouse gas emissions. However you will have to take the cost of the electricity used to operate the heater into consideration. Propane heaters can provide as much as 11 gpm and natural gas as much as 10 6 gpm.

We rated the annual energy consumption cost excellent for a gas. Electric water heaters typically have a lower upfront cost than gas water heaters. In many cases using an electric water heater will result in higher utility costs as compared to using a gas water heater.
