Water Heater Changes to Expect in 2015

How The New 2015 Water Heater Energy Efficiency Standards Will Affect Your Business: Are You Prepared?

On April 16, 2015, there will be significant changes to water heater energy factor (EF) requirements as the result of updates to the National Appliance Energy Conservation Act (NAECA). See below for some FAQs about these new standards. 

How will the 2015 standards affect the water heater industry?

  • The 2015 NAECA energy efficiency mandates will require higher EF ratings on virtually all residential gas, electric, and oil-fired water heaters. These changes will have an impact on how water heaters are designed, manufactured, distributed, and installed, affecting manufacturers, wholesalers, installers, and customers alike.

How will water heaters be affected?

  • Gas models will require additional insulation, incorporate newer flue baffling technologies (including flue dampers), incorporate electronic ignition in lieu of the standing pilot, or any combination of these. One impact will be an increase in the overall product size, especially in diameter. For gas-fired products over 55 gallons (< 75,000 BTU/Hr.), fully condensing combustion technology will likely be required. This will also mean that line voltage will have to be available, as well as a means for condensate disposal.
  • Electric models will require more insulation. This will increase the diameter and/or height of the water heater. Additional insulation may be required for piping and fittings such as drain and T&P valves. Electric water heaters over 55 gallons (< 12 kW input) will likely utilize integrated heat pumps to meet the new EF requirements.

How will this impact home builders?

  • Water heaters with capacities of 55 gallons or less, will likely be larger in size. Water heaters with capacities of 55-gallons or larger will incorporate new technologies such as fully condensing combustion or heat pumps.
  • Electric heat pump water heaters are generally taller than standard electric units and require a 10 ft. x 10 ft. room or a duct to an adjoining room to operate properly. Home builders must also be cognizant of the impact of noise, as heat pump models will operate at a higher noise level.
