On April 16, 2015, there will be significant updates to water heater energy factor (EF) requirements as the result of updates to the National Appliance Energy Conservation Act (NAECA). These new requirements call for higher Energy Factor (EF) ratings on virtually all residential gas, electric, oil and tankless gas water heaters as well as certain light duty commercial models.
EF Factor- The Energy Factor (EF) is the ratio of useful energy output from the water heater to the total amount of energy used to operate the water heater. The higher the EF rating, the more energy efficient the water heater will be.
What does this mean for you the homeowner?
Current Tank Water Heater Homeowners:
“The homeowner may have to deal with increased product and installation costs. In some cases, the water heater will have to be re-located to operate properly, or mitigate noise. While the operating cost of the new water heaters will be less because of their increased energy efficiency, it is likely that the maintenance costs will increase because of a more complex design, and the integration of electronics, blowers, fans, condensers, etc.” –Bradford White
Current Tankless Water Heater Homeowners:
These changes are already in effect for majority of tankless water heaters. Homeowners with tankless water heaters currently will not be greatly affected by these changes.
-Tankless water heaters- Are recommended to have 1x/yr. flushing/cleaning along with consistent treated water in order to maintain life expectancy, operation and in some cases warranty status.
-Tank water heaters- Yearly flushing of mineral build up in tank is recommended but not required at this time. New tank water heaters will require greater yearly maintenance after April 15th as they will have more components to meet efficiency standards. Maintenance will be required to maintain life expectancy, operations and in some cases warranty status.
