New Water Heater Energy Factor Standards 2015

Beginning April 16, 2015, updates to the National Appliance Energy Conservation Act (NAECA) will cause significant changes to water heater energy factor (EF) requirements. These updates require that virtually all residential, gas, electric, oil, and some light-duty commercial water heaters have higher energy factor ratings, which will have an affect on everyone, from homeowners to plumbers to builders and wholesalers.

Although these requirements may cause a few inconveniences along the way, the new standards made mandatory by the NAECA are estimated to save approximately 3.3 quads of energy and result in approximately $63 billion in energy bill savings from products shipped from 2015-2044, according to the U.S. Department of Energy.

 

EF is calculated using the following factors:

  1. Recovery Efficiency- how efficiently the heat from the energy source is transferred to the water.
  2. Standby Losses- the percentage of heat loss per hour from the stored water compared to the heat content of the water (water heaters with storage tanks).
  3. Cycling Losses- the loss of heat as the water circulates through a water heater tank and/or inlet and outlet pipes.

The EF rating indicates the water heater’s energy efficiency, based on the amount of hot water produced per unit of fuel consumed over an average day. The more efficient the water heater, the higher the EF. Your water heater’s EF can be found on the manufacturer’s label (circled in red in this image).

 

How The New Standards Will Affect You

Homeowners

  • The new regulations will save homeowners a considerable amount on energy bills.
  • The new water heaters will be larger, due to additional insulation, by approximately 1-2 inches in diameter and 1-2 inches in height, which may make it more difficult to replace existing products (some homeowners will have to find another space to store their new water heaters, if the storage space they have used previously is not large enough).
  • Before installing a new water heater, hire a professional plumbing contractor that understands the new guidelines, will know all of the product choices available for your home, and be able to recommend the best fit for your home’s needs.
