Water Heater Installation and Tax Credit

Heating water is the second biggest energy expense in your home.  Knowing your family's first hour water usage will help you get the right size heater.  Getting a heater that is too small will create havoc in your household, but getting a heater that is too big will cause you to waste money on the initial purchase and costs to keep all of that water hot 24 hours a day, 365 days a year.  

Energy Star Rating Requirements for all Residential High Efficiency Gas Storage Water Heaters:

  • Minimum energy factor of 0.62 now and 0.67 after August 31, 2010.
  • Minimum first hour rating of 67 gallons per hour.
  • Minimum six year limited manufacturer's warranty on the water heater.
  • Input of 75,000 BTU/hr or less
  • Rated storage volume between 20 and 100 gallons.

Heaters which qualify for The American Recovery and Reinvestment Tax Act of 2009:

  • Must have an energy factor of at least 0.82.
  • Must have a thermal efficiency of at least 90%.
  • The water heater must be “placed in service” between January 1, 2009 and December 31, 2010. The IRS defines "placed in service" as when the product is ready and available for use.
  • The water heater must be installed in or on the taxpayer’s principal residence in the United States.
  • The tax credit is ONLY available for existing homes.
  • This legislation includes 30% of the full purchase and installation price up to a maximum of $1500. The maximum amount that a taxpayer may claim for all qualifying energy efficient home improvements including the purchase and installation of a water heater is $1,500 over the lifetime of the credit (2009 & 2010).
  • Water heaters installed in 2008 are not eligible for the tax credit.
