“Awesome water heater brand!”
I have had a Rheem water heater for about 4 years. I had it professionally installed and it’s absolutely amazing. It always seems to have hot water available, and I do love my long hot showers. I have yet to have a single problem with it, as it still runs like I just bought it. I’m sure it will run perfectly fine for the next few years. I would totally buy other Rheem brands, I might consider a smaller unit as I think this one is too big for my current needs, It’s a huge water heater, just make sure you have enough clearance for it. I can’t complain about the installation or product cost either, good value for everything. If you want a good decent professional water heater, buy a Rheem!

I don’t know why others are complaining so much. My original A.O. Smith 50-gallon water heater, installed when the house was built in 1993, is still going after 23 years! I know what brand I’ll be buying when it finally does give up the ghost!

If you want a real answer, you’ll have to go out and ask an expert.
If you decide to get a water heater from this brand, keep in mind that Bradford White does not warranty its product unless it’s installed by a professional.

I have owned a Bradford White water heater for about 9 years now. What we like: It’s, in theory, energy efficient and has been without issue in the 9 years we have lived with it. What we don’t like: Sometimes slow to heat water and adjusting the temperature can be difficult. No repairs or replacement. I think I would recommend this water heater brand.

I finally installed a tankless water heater. If I would have known how much better this is, I would have done it sooner.

“Best tankless water heater brand, awesome bang for the buck!”
We have had an EcoSmart tankless water heater for 2 years and have not had to do any repairs. It is great because it is tankless and it saves a lot of space. I would recommend this brand to anyone who lives in an apartment or small condo and wants to save hundreds of dollars in initial expenses. However, one thing I dislike about EcoSmart tankless water heater is the sound it makes when it heats up the water, it could be kind of loud and gets annoying throughout the night.
6. GE GeoSpring Water Heater
General Electric has launched GeoSpring – the first hybrid heat pump electric water heater manufactured in the U.S. since 2014. And now, GE GeoSpring is the most popular heat pump water heater sold in the United States.
Many homeowners don’t realize their water heater is the second biggest energy-consuming appliance in their home. According to Energy.gov, water heating system can amount to nearly 17 percent of a home’s energy costs. So it’s important to consider a water heater which is as much energy-efficient as possible. The GE GeoSpring hybrid electric water heater is one of America’s most efficient 50-gallon and 80-gallon water heaters and saves the average household between $160 and $490 every year on their electric bill.
The GeoSpring is GE’s response to consumer demand for more efficient, environmentally friendly appliances. Some 60 million homes in the US use standard electric hot water heaters. By absorbing heat in the ambient air and transferring it to the heated water, the GeoSpring uses dramatically less energy. If 25% of all households switched to this hybrid system, it would reduce annual CO2 emissions to the same extent as removing 360,000 cars from the road.
Note: Haier bought GE Appliances, and GE Appliances stopped making the GeoSpring water heater at the end of 2016. So if you get a GE brand, it will most likely be old stock. And we’re not sure how that will change getting repair parts and service.

“Best hybrid water heater brand ever, save me 50 dollars a month on electric bills”
I replaced my old leaking 50-gallon gas water heater by a new GeoSpring 50-gallon. I’m getting plenty of hot water with the unit set on heat pump only & the water heater has dried out the basement!!! The unit makes about as much noise as a small fan, however after putting on the dishwasher & clothes washer “hot water cycle” I was able to take a long hot shower without seeing any loss in water temperature. Even without the rebates & tax credits, it’s the least expensive water heater you can buy.

“There is no better way than Bosch”
I’m glad I purchased Bosch tankless water heater, this been saving lots of money. At first had to get used to the difference between a tankless and a tank heater and be sure you have an electric junction box that can handle the electric requirements of this unit. Otherwise, it has been working great. I would buy the same brand again.

“I love Takagi”
I have owned a Tagaki tankless water heater for about 1 years and it is great. I like that it runs on natural gas and LP gas. I hope it lasts for many years. The only thing I don’t like about it is I have a large family so when we all need to take a shower in the morning right after each other sometimes the last person will not have enough hot water. So far we have not had to do any repairs. I think this is one of the best water heater brands on the market, strongly recommend!
10. Kenmore Water Heater
Kenmore has become an iconic brand since its first agitator washer was introduced 90 years ago. Today, Kenmore is one of the most trusted brands in the US. There are many Kenmore models at or near the top of our appliance ratings. And nearly one in three U.S. homes contains a Kenmore major appliance, according to Sears.

“Too pricey, but good”
I have owned a gas water heater from American Standard for a few months. It’s a large water heater, so I can take very long showers with no problem. It has a nice temperature stat on it which makes it easy to set it to the perfect temperature. But, it was too pricey, nearly $4,000 for a 50-gallon unit. While I could get the same model from Rheem at half price. I think this is a good water heater brand but the price should be lower.
