In 1925, two brothers, Richard and Donald Rheem had the idea to start the Rheem Company and with the financial backing of their other brother, William, they founded the company.

When starting, the company majored in galvanizing steel drums. However, this changed as years passed by, which saw the company diversify into other areas including water heaters.

In 1973, the company split into two with one half specializing in HVAC units and the other going for water heater units.

Since this division and specialization, the company has never looked back on its progress. It has manufactured and distributed high-quality tankless units, large-capacity tank units, exceptional customer service, and the continual incorporation of new-age technology.

6. Bradford White Heaters - Best International Water Heater Distributors

By limiting its products to specific dealers, Bradford White can easily monitor the movement and quality of their products more closely.

Common Types of Water Heaters

Before you settle for a particular brand of water heater, it’s best if you understand the types that exist so you can choose a brand that manufactures what you want.

Here are the three most common water heater options you can consider when you’re learning about the best water heater brands we test out.

a)  Tankless Water Heaters (On-Demand Water Heaters)

Tankless water heaters are quickly taking a significant space in modern homes. Everyone is looking for a convenient water-heating solution that will take up minimal space in their homes.

Tankless water heaters employ a slightly different principle of heating water. They heat water anytime you demand hot water, thus the name on-demand water heaters.

Anytime you open a hot water tap, cold water will flow into the tankless water heater via a pipe and then heats it quickly to release hot water.

Depending on the energy source, you can either buy natural gas or electric tankless water heaters. Either option will give you an endless supply of hot water anytime you need it.

The only thing you have to worry about when using a tankless water heater is its speed and flow. They barely surpass a flow rate of 5-6 gallons per minute.

b)  The Conventional Tank Water Heater

They are the first types of water heaters and, for a long time, the most common options in the market. These water heaters come with an insulated tank that stores water for heating. Water in the tank is heated up using electric or natural gas power sources.

Hot water in the tank will retain its current temperature and anytime you open a hot water tap, you will get a supply of the stored water.

Upon depletion of the hot water in the tank, you’ll have to wait for about an hour for the water to get reheated again.

This is one of the challenges you’ll have to contend with when using a tank water heater. Energy efficiency is also another topic you would want to discuss before buying a storage-tank water heater.

c)  Hybrid Water Heaters (Heat Pumps)

These water heaters work with the concept that it’s easier and cheaper to heat water using heat that already exists rather than producing heat to heat water.

A heat pump water heater will take heat from the air and use it to warm the water.

It compresses the surrounding air, forcing out the cool air and retaining the warm air that it uses for heating the water.

When hot water demands are high, this pump switches to using electrical coils for heating water. The name, hybrid water heaters, rose from the fact that they use two water heating systems to heat water; the warm air and the electrical coils systems.

However, to use hybrid water heaters efficiently, you must reside in an area with a warm climate, making it a not-so-perfect choice for cold areas or use during winter.

d)  Solar Water Heater

Solar water heaters are also commonly known as solar domestic hot water systems.

The solar system is connected to the hot water tank to absorb sunlight and convert it to heat for heating water.

With constant sunlight, using this type of water heater can be an economical way of heating water which is why some of the best water heater brands offer models like this. However, in cold seasons, you may need a backup plan to continue getting hot water flowing through your pipes.

e)  Condensing Water Heater

Condensing water heaters are energy-efficient gas-fuelled water heaters that ensure you enjoy a continuous flow of hot water into your home.

After being tested, they use 8 to 15% less energy compared to standard continuous-flow water heaters.

They manage to be highly energy-efficient because they preheat the incoming cold water with the excess heat tapped from the flue gas escaping from the appliance.

Once the flue gas has been used to heat the cold water, it condenses into liquid, hence the name condensing water heater.

What to Consider when Choosing Perfect Water Heater Brands

Once you have settled on the type of water heater you want, you need to consider other crucial factors before you choose the best water heater brands that ultimately meet your needs.

Here are some of the crucial factors to consider when buying your next water heater from the brands we try out and test.

The Source of Energy – Electric, Solar, or Gas Heaters?

More often the decision to either settle for an electric, solar, or gas heater depends on your home’s design.

Most homes use either gas or electric water heaters. These two only have a slight difference in the cost of installation and operation.

Changing from electric to gas water heaters is fairly affordable and you’ll need licensed and authorized dealers to perform the conversion.

If you’re thinking of using a solar heater, then you should pick it as a secondary option. It should supplement an already-running electric or gas water heater.

Solar water heaters are more reliant on weather patterns. When the weather isn’t favorable, you can easily switch back to electric or gas water heaters for a continual supply of hot water.

The perfect water heater brand or the best water heater brand is the one that sells water heaters that use the energy option of your choice.

The Presence of Digital Displays

With everything striving to go digital, water heaters are no exception.

If you are looking for the best water heater brands with models that are easier to operate, then you will go for a brand that incorporates digital displays in its water heaters.

Water heaters with digital displays will make it easier for you to monitor energy usage and easily control the settings to fit your needs.

Reliable water heater brands will sell water heater that has the best latest features including digital displays.

You should check if the brand you want to buy from incorporates this feature in their water heaters before paying for one.

Is the Water Heater Brand selling Glass Lined Tanks?

If you’re opting for tank water heaters you will need to optimize your specifications to get the best deal in the market.

One of the most attractive and admirable features of tank water heaters is their glass-lined finish. This unique glass-lined tank is made when glass and steel are fused to form a more durable outer layer for water tanks.

Settling for such a tank also means subscribing to reduced corrosion and buildup inside your water tank.

A leading water heater brand will use this unique finish to give their tanks the glow and strength they need to beat harsh weather.

The Water Heater Warranty

While two brands may have a water heater with almost the same qualities, a warranty may sometimes differ and this can help you decide the brand to go for.

When looking for attractive water heater warranties, don’t easily go for the longer warranty periods. Find out what the warranty covers before you go looking for the warranty period.

The typical water heater warranty period runs between three and 12 years. You can settle for the option that covers most of your insecurities and lasts the longest of all the available competitors.

FAQs about Your Popular Water Heater Brand

Going by the reviews and the testimonials we gathered, it is right to say that A.O. Smith beats the other brands to become the overall best water heater brand.

It has been around for a long time since 1874 and has consistently delivered excellent water heaters. They have diversified their products to cover almost everyone’s needs and are still selling at affordable costs.

The lifespan of a water heater is determined by many factors including how frequently you use it and how regularly you maintain it among other factors. The heater’s brand also makes for a significant factor influencing the water heater’s lifespan.

Going by brands, Rheem has continually proven to be the best water heater brand when it comes to durability. This is thanks to its award-winning construction that makes it rigid and firm for the harshest conditions.

One of the most common water heart problems is water temperature issues. You’ll probably have to deal with cold water, warm water that doesn’t get hot enough, or water that is too hot than what you needed.

While some of the water temperature issues can be solved using digital control features, not all brands include the app in their water heaters.

You can always settle for brands that have digital control apps linked to their products so you can be safe when handling such heaters.

Comparing the two, an electric water heater is more efficient than a gas water heater. However, a gas water heater is more cost-efficient.
