On the contrary thermal efficiency is the amount of energy delivered as heated water compared to the energy consumption of the water heater.

Water heater energy factor vs thermal efficiency.

The term is used by the united states department of energy to develop and enforce minimum energy conservation standards under. Most new water heaters have an efficiency factor ef of 58 60. Adjustments in new doe testing procedures now impact water heating performance stats associated with the amount of hot water produced in a real world situation to the length of typical showers. An older measure of water heater overall efficiency that is being phased out due to new test methods for water heaters.

Energy factor calculates the amount of energy delivered as hot water compared to the energy consumption of a residential water heater over a 24 hour period. 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. That means that 58 60 of the energy that is being used to heat your water is effectively converted into heat. Water heaters are the second highest source of energy usage in the home.

The energy factor is currently used for rating the efficiency of water heaters dishwashers clothes washers and clothes dryers. They use less energy than standard models saving homeowners money on their utility bills while helping protect the climate. Add up your savings. Examples of performance factors impacted by uef include.

Use the energy factor to determine the energy efficiency of a storage tankless or demand type water heater or heat pump water heater. That means that 58 60 of the energy that is being used to heat your water is effectively converted into heat. Find out how much you can save on energy costs when you purchase your rheem hybrid electric water heater. Added smart features like exclusive water leak detection alerts and vacation setting plus energy cost savings and our 10 year warranty all add up for a quick payback in less than two years 11 and big savings over the life of the water heater.

Expressed as a decimal the uniform energy factor is determined by running a department of energy specified simulated use test sut. The uniform energy factor. Energy star certified water heaters are an easy choice for energy savings performance and reliability. What energy efficiency rating factors have changed.

They can be 8 14 more energy efficient for homes that use a lot of hot water around 86 gallons per day. Ef is determined by the department of energy s test method outlined in the 10 cfr parts 200 to 499 edition revised as of january 1 2014. The two figures are related but different. The higher the ef value is the more efficient the water heater.

An energy factor is a metric used in the united states to compare the energy conversion efficiency of residential appliances and equipment.
