A hot water heater is important for your home. It's pretty hard to live without one. And while there are plenty of options out there, certain brands or models are a bit better than the rest. 

There are certain brands that have become somewhat synonymous with residential water heaters. And for good reason, too; those are the brands that are super reliable and make for great options for the average consumer.

No matter which type of hot water heater you decide to go with, you’ll be able to find one from a really reliable brand. There are a lot of options out there for gas and electric, and for tank and tankless. Here are the best hot water heater brands around, each offering great product selections. 


A.O. Smith

A.O. Smith is kind of an American staple at this point. Specializing in tank electric and gas heaters, while also making a foray into the tankless market, there is really an A.O Smith heater for anyone. 

This brand is known for its reliability and quality. If you end up going with one of their models, you can rest assured knowing that you’ll be getting something that will last you a long time.

And with their selections of warranties, you won’t have to worry about them breaking down, either.



Rheem is another brand that’s synonymous with the hot water heater. This all-American company offers a variety of heating and cooling products, but they’re probably best known for their water heaters. 

Rheem is also known for having outstanding quality and long lasting products. Like any other reputable brand, their units are Energy Star certified, so you know you’re going to be getting something efficient. 

Just like A.O. Smith, Rheem has a large selection of gas and electric tank water heaters, but also carry tankless options. There’s definitely something for everyone with this brand.



Westinghouse is another brand with a lot of experience under its belt. Like other entries in this list, Westinghouse offers a variety of gas and electric hot water heaters, both tank and tankless.

As a company that specializes in home heating, they also carry a line of space heaters.

What’s really interesting about Westinghouse’s lineup is, as a heat-specializing company, they offer combination hot water heaters and space heaters. That means you can heat your house and water at the same time. How cool is that?

Aesthetic-wise, Westinghouse has some really pretty models with innovative technological components. You can rest assured knowing if you go with this brand, you’ll be getting quality and longevity.



A company of German origins, Bosch is known for making long-lasting products with quality in mind. The company offers a variety of different appliances on top of heating and cooling systems. They also offer high-quality hot water heaters of the tankless variety.

With both gas and electric tankless water heaters under their belt, Bosch provides awesome, energy efficient products that are built to last.

They don’t offer any tank models, but for anyone who is interested in looking into tankless, this is definitely one brand name to keep note of.



Rinnai is a Japanese company that offers different heating and cooling options. Stateside, they’re probably best known for their line of highly efficient tankless hot water heaters.

Rinnai is definitely a name that’s commonly associated with tankless heaters specifically, and it makes sense, given how spectacular their products are.

With both gas and electric hot water heaters to choose from, Rinnai is a brand that anyone who’s interested in going tankless should know. This brand is seriously no joke. 



EcoSmart is another brand that specializes in tankless models, both electric- and gas-powered. Their products boast high energy efficiency and incredibly long lifespans.

They also offer pool and spa heaters, so if you need some heat in your swimming pool or hot tub, you’ll know where to go.

EcoSmart boasts long warranties on their products. This is really good because, let’s face it, things break down or stop working as well as we’d like them to. Having that extra peace of mind is really important when shopping for a water heater.
