A new update to the rules for increasing minimum energy efficiency standards was enacted in 2010 and goes into effect on April 16, 2015.
Water Heaters Under 55 Gallons
- 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.
Water Heaters Over 55 Gallons
- Water heaters that are larger than 55 gallons will undergo the biggest changes. They may require more space or potentially switching models.
- All residential electric models over 55 gallons must be of the Hybrid Electric heat pump water heater type design
- All residential gas models over 55 gallons must be of the condensing water heater type design
