My water heater is going out. Instead of paying $200 to repair it (1 year warranty), I am buying a new gas GE (Rheem) 40 gallon tall water heater with a 6 year warranty. It is being installed by a Home Depot contractor for $643 (unit and installation). This includes take away of my old Rheem water heater.
The regular price is $661 in my area (Indianapolis) so it is on a small sale. In addition, I should get 5% back on my Chase card through June 30th.
A 50 gallon is a little more. Extending the warranty to 9 or 12 years is quite a bit more.
Plumbers are significantly higher (over $1000 total) for a similar model and warranty water heater installed.
Lowe's also does water heater sales and installation, but their Whirlpool brand has gotten awful reviews.
I did not see any other water heater threads and since the savings using Home Depot over a local plumber is huge, I thought this might help people out.
You can call 1-800-HOMEDEPOT to order. Going into the store was pretty worthless.
