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.

Excellent Performance and Reliability!

matt346 2/18/2025

I recently installed the GE® 40 Gallon Tall Electric Water Heater (Model #: GE40T08BAM), and I'm extremely impressed! It consistently delivers a reliable supply of hot water even during peak hours, and its energy efficiency has noticeably lowered my utility bills. The compact, tall design made installation a breeze, fitting perfectly into my limited space. This water heater is a true game-changer for home comfort™€"highly recommended!

able to adjust temperature

my nickname has been used 6/28/2024

the water heater is very good. When the old one broke I was going to have a hard time ordering a new one because the area of the old one was in a very tight space. However the plumber was able to get this one that was tall and narrow, which fit into the tiny space.

We Love GE Products

woodman1 6/12/2024

We have always purchased GE appliances and have had exceptional service. When it was time for a new water heater, GE was my first choice. However, I could not find any sources near Albany, GA, to purchase a GE water heater. I drove 200 miles to Atlanta to purchase a GE water heater from BrandsMart. We hauled the water heater to our condo in Panama City Beach, FL, and installed. It works great.

Horrible Experience. Unsafe condition.

Ivan24 1/30/2024

Water heater is building pressure over 140psi at different temperature settings; this is telling me that at least the thermostat is bad. However, GE Customer Service, defying physics principles is saying that the equipment is working properly and that I need to install an expansion tank so the water heater can work properly. This is absurd. Their customer service is terrible; they do not listen and just follow a script. If you ask too much questions they rise their voice and keep not listening.

Third Time Was the Charm....Water Heater Nightmare

SocoLisa 3/9/2023

The first water heater that was installed would not produce hot enough water even when set a 140 degrees. Turns out that one of the heating elements was defective. Plumber replaced heating element and the water temperature wasn't over 120 when the thermostat was cranked up to 140 degrees. Plumber replaced the unit with another one and guess what? Same issue....couldn't get the water in the heater hot enough. With the water heater set at 140 degrees, I could hold my hands under the hot water coming out of the faucet indefinitely. I would run out of hot water after a 12 minute shower and I don't take really hot showers. I live alone so no other hot water was being consumed prior to showering. Plumber came out again and replaced the GE water heater with a Rheems, which is what I intially wanted but because there wasn't one available and I needed a new water heater ASAP, I went with the GE. Getting a new water heater should not be a PTSD producing experience.

Better than expected...

I'm not 100% sure how I feel until the power bill shows up for the first month after install. The heat is comparatively the same as gas just takes alittle longer to reach the upstairs shower.

Manufacture Date: 2019??? Faulty

Michelle9027 8/15/2022

Hello, My brand new hot water heater was delivered in June, installed in July, and has worked intermittently since installation. GE warranty will not cover this brand new hot water tank because it was manufactured in 2019. Where has this hot water tank been stored for the past three years? I need a replacement but I™€™ve been unsuccessful

Not quite perfect

MarieSolange 7/11/2022

The brand new GE water heater unit was installed by Ameriflow. Four days later, there was still no hot water. Ameriflow diagnosed a faulty thermostat. I am told their replacing it does not void the 8-year warranty. I would have appreciated being able to contact GE by phone, but I could find no number for GE in the Owner's manual. Hopefully, the new thermostat will have fixed the problem.

Water doesn't get really hot unless the adjustments are turned almost all of the way up. So no energy saving here.
