Choosing a water heater for your home can be a big decision. There are many options, and you need to get it right – water heaters are not cheap, and you are likely to be using the one you pick for many years to come.
When making your decision, there are a number of factors to take into account, but one major consideration is the brand you opt for. Many companies produce water heaters, and it can be hard to know which is best for you – so here are our top picks for best water heater brand to help you make up your mind.
1. A.O. Smith
When it comes to water heaters in the North American market, one of the first companies to be mentioned will always be A.O. Smith. This company was founded in 1874 in Milwaukee, Wisconsin – and the company is still based there to this day.
When the company was formed, it was no more than a local hardware shop, but in the years that followed, the family outfit branched out into making steel car frames and then innovative water heaters.
Their products are now sold by plumbing wholesalers and contractors only, and their range includes tankless, hybrid, solar and tank-style heaters.
While any heater from A.O. Smith will be a solid investment, the company is especially known for its gas heaters – they are among the most reliable and most efficient currently available.
In fact, many of their products carry Energy Star efficiency certification, making them eligible for tax credits or rebates under some local energy-saving schemes.
The company produces a range of high-efficiency electric heaters that are worth checking out.
Many of the company’s solar-powered options are also eligible for tax credits or rebates and could be a good option if you are looking to save yourself some cash in the long term.
Rheem was founded in 1925 by two brothers, Donald and Richard Rheem – and with financial backing from a third brother, William.
Originally, the company was involved in galvanizing steel drums, but in the subsequent decades, they diversified into other areas, including water heaters among other things.
The company split in two in 1973, with one half focusing on air conditioning units while the other, the Water Heater Division, concentrated on water heaters.
Since then, the company has built a reputation for high-quality products, exceptional customer service and cutting-edge innovation.
Rheem now produces a full range of water heaters, including solar, gas, electric, tankless and heat pump models. Their tankless heaters are among the most popular in the US while their storage heaters are known for their reliability and their low maintenance requirements.
As one of the best-known and longest-established brands, their products come highly recommended – buying from a company with nearly 100 years of experience automatically gives you a certain amount of reassurance.
Furthermore, Rheem’s tankless water heaters are among the best available in their category, and if this is the kind you are looking for, Rheem should be high on your list of possibilities when deciding which brand to go with.

Kenmore might be better known for making household appliances such as kettles, coffee machines and vacuums, but the brand also produces a line of highly respected water heaters.
Founded in 1913, the company has hugely diversified its product range down the years. It is thought that one in three American homes now owns at least one Kenmore appliance.
In terms of the company’s water heaters, the range includes electric, hybrid, natural gas and propane versions. As with the rest of Kenmore’s range of appliances, the company’s water heaters are known for their solid performance and their high levels of reliability.
The company is also willing to back its products, offering warranties of between six and 12 years, among the most generous you will find.
All Kenmore water heaters are built for efficiency, and the electric models, in particular, are good at retaining heat and therefore consuming less power.
Most recent models are also compatible with the Kenmore app, allowing you to control your water heater via your smartphone – which means you can change the settings even when you are away from home.
4. Bradford White
If you are the kind of person who believes buying products made in the USA is a guarantee of higher quality and reliability, then Bradford White is another manufacturer of water heaters that should be of interest.
This is a company that only sells their products via authorized representatives and wholesalers, meaning you can’t simply go out and buy one for yourself. The company places great importance on producing the highest quality equipment, and by using a network of authorized dealers only, the company is able to monitor quality more closely.
The company only offers a warranty if their heaters are installed by authorized professionals – but as long as it is installed by an officially certified plumber, you will receive a warranty of around 10 years, among the best in the market.
Some people might baulk at the initial cost of choosing this brand – Bradford White heaters are generally priced quite a lot higher than many comparable options. However, their heaters are superior products, and the increased reliability and low maintenance costs down the line will mean you end up saving money in the long run.
The company produces both gas and electric models, and if you are the kind of person who is willing to pay more for the best products, this is a brand you should consider investigating further.
5. American Standard
Founded over a century ago, American Standard is a well-known company with a wide range of products that includes bathtubs, sinks, faucets and many more kitchen- and bathroom-related fittings.
It also produces a range of high-quality and reliable water heaters of most types – the company produces electric, heat pump, natural gas, propane gas, tankless condensing and storage tank models.
The company’s products are designed for both the commercial and residential markets, although many of their water heaters tend to be larger, more powerful models that are more suited to commercial applications.
Their units are often sold at higher prices than comparable models by some of the other brands in this review, and some home users might be unwilling to meet the price tag. However, if you are willing to pay more to get your hands on a water heater of superior quality, American Standard is a brand that should be on your radar.
In terms of the warranty, American Standard heaters come with four years as standard. While this is more than some brands offer, it is by no means industry-leading, and if a long warranty is one of the most important factors for you, better options are available – especially at the higher price you will pay for this brand.

6. American Water Heaters
While this company might not have the pedigree of some its more venerable rivals – it was only founded as recently as the 1970s – it has worked quickly in a relatively short time to establish itself as a reputable manufacturer of water heaters.
The company is now owned by A.O. Smith but continues to make high-quality heaters under the American Water Heaters brand.
The company produces a range of different heaters including gas and propane models, electric heaters, tankless versions and solar-powered options. All models across the range, from the smallest and most basic, are known for their efficiency and reliability. In particular, most of the options in this company’s range are good picks if you care about the environment.
For the most part, water heaters from this brand tend to be at the smaller end of the scale and are most suitable for small or medium-sized homes. The company also makes electric water heaters that are specifically designed for mobile homes, so if that’s what you are looking for, this is a brand that should be near the top of your list.
Founded in 1886 in Stuttgart, Germany, Bosch has long been at the forefront of engineering and technological innovation, and the company’s hallmarks are high levels of quality and reliability.

If you are looking for a water tank that gives you the best bang for your buck, is kind on the environment and that will also last a long time, EcoSmart is a brand that should be of interest.
This company specializes in producing efficient, environmentally-friendly electric tankless water heaters that sell for less than many of their competitors’ units but that are able to outperform larger heaters due to their innovative SmartBoost technology.
In effect, this allows EcoSmart water heaters to produce the same amount of power as a unit of up to 45% larger. This, in turn, can help to reduce your monthly electricity bills by up to 60%.
You might imagine that for such an efficient unit that can reduce the amount you spend on electricity each month, you would have to pay more upfront. However, EcoSmart heaters cost less than many of their rivals, making this a no-brainer in many ways.
These units are also designed to last longer – the company is so confident in the quality of its products that they are willing to back it with a limited lifetime warranty.
For anyone who wants to save some cash and reduce their monthly bills while doing their bit for the environment, this brand is an obvious option. The only issue some people might have is that this company is a newcomer without the history or experience of some other brands. However, if you are willing to give them a go, you are unlikely to be disappointed.

Navien is another young company with many of the same attributes as EcoSmart. Founded in 1978, the company set about establishing itself as a brand that’s known for highly efficient, environmentally friendly water heaters.
The company specializes in making tankless water heaters, and their range is not extensive – instead, the company has limited itself to concentrating on only a handful of models and making sure each one is exceptional.
The company produces two lines of heaters, the NPE-S line, the standard models, and the NPE-A line, Navien’s upgrade options. Both lines of heaters are among the most efficient available and will help reduce your electricity bills. All the company’s heaters are Energy Star and LEED-certified.
This is perhaps not the best-known brand, but sometimes this can be an advantage. Although when buying from a less famous brand like Navien, you don’t have the peace of mind that comes from buying a product from a well-established company. However, you are paying for the product only and not the name – and that means you are likely to get far better value for money.
Noritz is not among the most famous brand name, but this is a company that specializes in producing a range of high-quality yet affordable tankless water heaters that represent great value for money.
The company was originally founded as Noritz Bath Industry in Kobe, Japan in 1951, and back then, the company’s major focus was gas bath boilers and furnaces. In the years that followed, the company began making tankless water heaters and then instantaneous heaters.
Nowadays, the company has a presence in the US as well as in Europe and Australia. Noritz continues to produce outstanding and environmentally friendly tankless water heaters that help you save money at the same time as helping to protect the planet.

Reliance was originally a part of State Industries when it was launched in 1981 but has since been acquired by A.O. Smith. However, Reliance continues to produce its own branded water heaters, which are known as some of the greenest options available.
The brand makes gas and propane heaters, electric heaters and tankless heaters – Reliance tankless heaters, in particular, are considered to be among the best available.
All Reliance products incorporate the latest technology, and the brand is always trying to push forward with new developments. Reliance has a wide range of products, meaning most people should be able to find the right model for their requirements, and this a brand that many people would do well to consider.
Rinnai is another well-established brand that traces its history back to Japan, where it was founded in 1920. At the beginning, the company made gas appliances like pressurized cooking stoves. After a brief hiatus during the war years when they switched to making aircraft parts, the company went back to making its original area of expertise. They began making their first water heaters in the 1960s.
Their current range consists of four lines of tankless models with increasing efficiency as you progress from the standard units to the top-end versions.
