Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Waterheater review

dollydmed 9/29/2025

This is my second GE waterheater . My old one lasted 22 years without no issues. Why I ordered another GE tank. But this second waterheater tank came with dent at the bottom. Didn™€™t see any packaging damage. Reported this to GE and Wayfair. Waterheater was installed since the old one was taken out. So far waterheater is running fine.

Bslocum 12/13/2024

This water heater is trash. It™€™s only 18 months old and the control box went out. I had to pay a plumber to come put a new one in . When I called they sent me a new part at no charge but only because they have had so many complaints on this particular control box. 4 days later the new box goes out. Now best case senerio they send me another box that I have to pay another plumber $200 to change this box out that may or may not work for 2 days. They had a recall on the box but evidently done nothing to correct the problem. I might as well bite the bullet and go ahead and purchase another brand water heater

Hot water heater

SS38372 10/28/2024

A cheaper version than what I bought 14 years ago. Not a fan of plastic replacing metal on the gas valve drain valve and pressure release valve. But this is the world we live in. Seems to heat water great. Looks good. I guess the blinking led light is an interesting feature that I didn™€™t need at all but had to pay for. Hope it last 10-15 years without flooding my basement.

POOR Service, put a pretty tank

Billy Stepps 6/18/2024

After 1 year and 6 months this water heater quit working. It gave a code of High Temperature Shutdown. You can not talk to a technician to try and trouble shoot it. I was given the following phone numbers: 800-626-2005,800-943-8186,800-432-2737 and 800-621-5622. After 1 hour and a half I have yet to talk to a technician and attempt to trouble shoot. Once they found out I was out of the yr warranty then it was no longer their responsibility and I was find a plumber on my own. The product might be okay but the automated service and larger number of departments combine with the expert advice of talk to someone else, "Here is the phone number you need to call" makes this product almost worthless in my book. I would strongly recommend finding another company to buy from .

An upgrade?

TSB73 11/10/2023

I chose to upgrade(?) to a GE water heater with eight year warranty instead of replacing the (different brand) with three year and recurrent issues. We™€™ll see how the investment fares in five years? So far, we™€™re very happy with this water heater.

Great hot water heater

AmandasCool 9/23/2022

GE has always been a brand that I feel I could rely on. With this hot water heater I feel no different. Installation took about two hours for the plumber. After watching the plumber I feel like I could have installed it in my own, but I don™€™t like taking chances when it comes to gas appliances. There are many safety features on the unit, which I appreciate. There is only my husband and I in the house so the 40 gallon size works very well for us. The water is always hot. I™€™m happy with it and would recommend it to others!

kobegiant 9/11/2022

My water heater broke down and I've gotten this just in time. I'm somewhat an intermediate DIYer so I tried installing this by myself. Overall, everything went well.. Perfect size for my house. Durable, easy to navigate and install and works as it should. Two thumbs up and definitely recommended for those average size house looking for a water heater.

Very easy installation for this unit. We have had no issues since installing this hot water heater for our family of 3. Always plenty of hot water for us to shower after each other and no one is left with cold water at the end. Husband had installed in about an hour.

Awesome Water Heater!

jsgarden 8/21/2022

My husband and his buddy just recently installed this hot water heater in our basement. His first impression was that it was not difficult to set up. He had to adjust for the tallness of it, but it was easy enough. He was able to get it installed within an hour. We are a family of 3 and have not had any issues with running out of hot water. He is happy that it has an anode rod as it will help with not rusting as fast as other brands. He is interested and is reading up on the LED indicator that reports on gas system statuses. We needed 2 people to get it into our basement as it is heavy! We are very happy with the GE RealMAX Classic 40 gallon gas water heater and we will have years of use with it. Thank you GE for making such a quality product.

Italianqueen88 8/20/2022

We™€™re extremely impressed,the delivery was effortless! It was packaged exceptionally well and delivered safely,my husband and my son carried it down to the basement and installed it themselves. It took about 2 hours with cleaning up and having hot water running into the sink!!!! I love the LED features where you can see everything instead of what are old one which was from 2006 had to get under it! We have been using it now about 3 weeks with out any issues and it™€™s is really impressive!! It™€™s taller then are old one but not an issue. Definitely happy and impressed!

We set this up as a tandem to our current water heater. (Same size) boy the difference is amazing! My husband has a novice experience in installing water heaters. This was my first. We spent a Saturday getting this installed. And didn™€™t really have any issues. We™€™ve had it now for 6 weeks and we have yet to run out of hot water. It™€™s great! I definitely recommend!

I installed my new GE RealMAX Choice 40-Gallon Gas Atmospheric Water Heater a few day™€™s ago, and couldn™€™t be more pleased with my choice of products. The installation itself was a very smooth process, and the Manuel was easy to read & comprehend. Since the installation we™€™ve had consistent hot water with the appropriate hot water pressure. If you™€™re in the market for a new hot water heater I highly recommend the new GE RealMAX Choice 40-Gallon Water Heater Heater.

Quality GE gas hot water tank, plenty of hot water

jde8080 7/30/2022

I want to say that I am a supporter of GE products, their products are well made and built to last. As far as this GE hot water tank, we had it installed the weekend it was delivered. It was delivered on a friday and we installed it on a saturday. We have had it installed for about 1 week now without problems. The item was delivered and packed well. I had my father in law help me move it to the basement and install it after we drained and removed our old one. The setup was well explained in the manual and after we installed it the pilot light worked right away, we had hot water within the hour after installing it. The paper manual was inside the box as well as available online where I also registered our hot water heater. The serial number and all that available information was also available online to be able to download and save. We have not run out of hot water yet, with the size of our family we do so much laundry and dishes. We have not had an issue with running out of hot water in the evenings for baths and showers.

whowser 7/30/2022

The RealMAX Water Heater is a design that offers long-lasting protection against corrosion to extend the life of your water heater. It can quickly replenish hot water and it also monitors the air around it and shuts off in abnormal temperatures. It is rust proof which extends its life. It includes standard water and gas connections, so easy to install.

Best Water Heater!

Drea1 7/27/2022

This water heater was so easy to install that it took more time to get the old one out then it took to install the new one! Let's talk about how quick the hot water replenishes because that is super important!.We took 4 showers without running out of hot water! That is unheard of with the others that we have had! I absolutely love it and I highly recommend!
