Warranty coverage for most water heaters is typically anywhere from three to 12 years. Water heaters that come with longer warranties usually cost a bit more.
There are a few water heaters recommended by Consumer Reports. The Whirlpool 6th Sense 40-Gallon 6-Year Short Gas Water Heater N40S61-403 comes with a six-year parts and tank warranty, as well as one year of included labor. Another recommended water heater is the Rheem Fury, which is backed by a six-year warranty for its parts and tank. There are not many owner-reported problems with this water heater, but some customers have complained that Rheem doesn't honor its warranty for certain situations.
The Ecosmart water heater provides a lifetime warranty on the element, electronics and exchanger, but the warranty does not cover the cost of labor. Requirements for the warranty to be valid are detailed on the company's website, so customers should review those details thoroughly, so they understand the specifics of the warranty. Owners report that it is easy to find replacement parts for these heaters at their home appliance retailers.
The GE GeoSpring water heater comes with a 10-year limited warranty for part replacement. However, the cost of labor is covered for only one year.
