Water Heater Efficiency Comparison Chart
A conventional water heaters energy efficiency is the Uniform Energy Factor UEF which is the amount of hot water produced per unit of fuel consumed in a standard test.
Water heater efficiency comparison chart. What Energy Efficiency Rating Factors Have Changed. Water heater types are listed below in order of overall energy efficiency as follows. The new UEF standard affects more than just the efficiency number itself.
Use our guide to research the best water heater company for you. For safety concerns as well as energy efficiency look for gas-fired water heater units with sealed combustion or power venting. This is a savings of around 63 billion in energy bills and will remove 1725 million metric tons of carbon dioxide.
Technology continues to improve the energy efficiency of water heaters. By DOEs estimations under the new regulations water heaters shipped between 2015 and 2044 will save approximately 33 quads of energy. The Rheem Performance Platinum Hybrid High Efficiency Smart Tank Electric Heater took our overall prize.
Almost all homes and businesses need a water heater on-site. Buying a water heater. The overall system efficiency of an electric heating system-including.
Compare Water Heating Costs. Sealed combustion or direct vent is a two-pipe system one pipe brings outside air directly to the water. A Quick Comparison of Water Heater Types by Efficiency.
For example a high bin water heater with a UEF of 095 does not perform exactly the same as that of a low bin water heater with a UEF of 095. The higher the UEF value is the more efficient the water heater. Natural gas price is a.
Electric water heaters tend to have at least 98 thermal efficiency many are 99 percent or more. As the result of recently updated efficiency standards water heaters less than 55 gallons now have a 4 percent boost in efficiency and water heaters 55 gallons or more have efficiency gains of 25. A water heaters UEF can only be compared with water heaters within the same bin.
By 2010 according to the American Council for an Energy-Efficient Economy water heater efficiencies could be organized and described by an energy efficiency factor. Similarly electric heaters can have higher energy factor ratings than gas heaters. Look at how the costs compare over the life of a standard water heater in Comparing the True Cost of Water Heaters Sealed combustion.
Gallons-per-day temperature rise cost-per-unit and energy factor values are all adjustable. Actual performance may vary. UEF is determined by the Department of Energys test method outlined in 10 CFR Part 430 Subpart B Appendix E.
It is Energy Star rated with an impressive energy factor of 355 allowing you to recoup hundreds in energy costs each year. In fact UEF provides a more consistent and accurate way to measure energy efficiency performance in water heaters across all national brands. In comparison gas heaters usually have between 80 and 85 percent.
It is a quiet reliable piece of machinery with high-quality elements that reduce the chance of maintenance issues over time. Adjustments in new DOE testing procedures now impact water heating performance stats. The chart to the right illustrates the change in efficiency requirements for the different types of water heaters.
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. Default energy prices last updated. Electric water heaters are often considered to be close to 100 percent efficient.
How efficient is propane over electric. This is true at the point of use. This calculator shows the approximate costs of heating water for a typical family.
This calculator is for comparison purposes only. A higher UEF means a water heater is more energy efficient and will cost less to operate compared to other water heaters in the same bin. All this can offset the higher cost of electric power to some extent.
Before you can choose and compare the costs of various models you need to determine the correct size water heater for your home.
