Electric Water Heater Efficiency Comparison Chart

There are two types of solar water heating systems.

Electric water heater efficiency comparison chart. Typically electric water heaters are similar to gas water heaters in efficiency. If you purchase one of the best electric water heaters then you re getting the most affordable large scale option that is available for your home today. One type of water heater may use a fuel type more efficiently than another type of water heater. Electric water heaters tend to have at least 98 thermal efficiency many are 99 percent or more.

Efficiency standards for gas and electric water heaters are different but both use the uniform energy factor uef ratings system where higher scoring units produce more hot water while using less energy. Electric units can also last longer compared to gas water heaters and offer lower installation costs. In all aspects electric tankless water heaters offer higher efficiency longevity and more. The efficiency of an electric water heater unit can be as high as 99 percent while gas units have an efficiency of up to 80 85 percent.

A gas water heater uses the heat from burning a fuel usually natural gas to heat water while an electric water heater uses electric resistance coils. The type of water heater you choose will also affect your water heating costs. Investing into an energy efficient water heater is one way to save money on your monthly utility costs. Similarly electric heaters can have higher energy factor ratings than gas heaters.

Gas water heaters are less energy efficient than electric heaters but the cost of electricity itself m. As the result of recently updated efficiency standards water heaters under 55 gallons now have a 4 percent boost in efficiency while water heaters 55 gallons or more have efficiency gains of 25. However the cost of electricity makes their operating cost higher. Solar water heaters are great but they often work better as a secondary system heating the water or keeping it hot without eliminating the availability of water heated by gas or electric.

Active which have circulating pumps and controls and passive which don t. The price of an electric water heater varies. 50 more efficient than gas electric water heaters. There s more on the types of solar water heaters here lasts about 20 years.

Solar water heating systems include storage tanks and solar collectors. For example an electric heat pump water heater typically is more energy efficient than an electric conventional storage water heater. To earn an energy star certification for example electric water heaters with tanks up to 55 gallons must have a uef greater than 2. Electric water heater vs gas water heater comparison.

Electric models are usually 10 lower in product price compared to similar gas.
