For more information about choosing the right gas water heater for your home, see the Constellation Home Hot Water Heater Buying Guide.

Gas Water Heater Warranties

There are many warranty options for your new water heater, but coverage and price depends on the size, make and model of your water heater. The base manufacturer’s tank leakage warranty starts at 6 years and protects against many water heater malfunctions. Upgraded warranties of up to 12 years are also available on certain tanks.

  • Extended Labor Warranties are available to provide additional peace of mind
  • All of our Gas Water Heaters come with a free 1-Year Parts and Labor Warranty
  • Contact an Energy & Comfort Consultant to learn more

FVIR Technology

Flammable Vapor Ignition Resistant (FVIR) is an American National Standards Institute (ANSI) standard, which requires water heaters to be constructed in order to prevent ignition of flammable vapors outside the combustion chamber. The following technologies are included in every gas water heater installation, regardless of manufacturer.

  • Flame arrestor plate, the single biggest component change in the FVIR designs.
  • One-way intake system to control the movement of makeup air into the combustion chamber.
  • Sealed burner access door and burner assembly, preventing combustion air and flammable vapors from entering the chamber through the front of the water heater.
