As part of the National Appliance and Energy Conservation Act (NAECA), new energy codes from the Department of Energy mandate that residential water heaters manufactured as of April 16, 2015 improve R-values of the insulation around the tanks. This mandate will result in new water heaters being taller and wider than older models. McCoy’s 30-, 40-, and 50-gallon model water heaters are affected by these changes.

With diameters and heights of many water heaters increasing up to 15%, installation issues may occur when replacing an older model. If your water heater is in a confined space or in a closet, the new model of the same gallon capacity may not fit within that same space.

BE SURE TO MEASURE YOUR SPACE AND DOOR OPENING BEFORE BUYING A NEW WATER HEATER.

• The height of a new unit with the same gallon capacity as an existing unit may be two or more inches taller
• The diameter of a new unit that has the same gallon capacity as an existing unit may be two or more inches
  wider
• For units under 55 gallons, add a minimum of three or more inches when planning the space

• For installations where space is not an issue, units of similar gallon capacity but larger in physical size can
  be installed.
• For installations where space is an issue, a similar unit with smaller gallon capacity may be installed or a
  unit with different technology may be a good option.
