What Makes a Water Heater Brand Great?

When determining a water heater brand for your next big purchase, these elements could hold weight on your decision.

Energy-Efficient 

With today’s technology, there is no reason why any brand should offer a major appliance or product that is not energy-efficient. Consequently, they are one of the second-highest products that account for the total household energy consumption.

So, finding one that uses less energy is vital. Not only will it save you money on your monthly bills, but it will also reduce your overall carbon footprint.  

Reliability 

No one wants to have their water heater quit or have performance issues. Choosing an exceptional water heater brand means finding a reliable and long-lasting model, so you don’t have to worry about its performance or operation.

Water heaters should provide hot water when you need it, without worrying about taking too long in the shower or running too many loads of laundry.  

Warranty Coverage 

Purchasing a water heater is not a regular occurrence. These products can last anywhere from 8, 12, or even 20 years, depending on the style and model. A reputable manufacturer will offer customers exceptional warranty coverage if they face any problems or issues with regular operation during the unit’s lifetime. 

The Best Water Heater Brands

We break down each of these brands into more detail below so you can determine which one will suit your household requirements. Unfortunately, not every brand will carry all model types, so your choices may be limited if you’re searching for solar or tankless systems. 

1. A.O. Smith

A.O. Smith specializes in providing versatile, high-efficiency water heaters. Whether you’re looking for an electric model, gas-powered, a tankless system, or a hybrid system, they have everything you need. 

Their powerful water heaters are not only efficient, but customers are also impressed with how quiet they are. In addition, A.O. Smith uses commercial-grade components to ensure longevity, durability, and reliability in a home water heater. 

Typically, A.O. Smith’s gas-powered water heaters are cheaper to operate than electric models but can cost more upfront, with installation and ventilation costs.

A.O. Smith’s electric water heater units have a UEF (Uniform Energy Factor) rating between .89 and 3.45, making them highly efficient in saving you money on your monthly bills. A.O. Smith offers a hybrid water heater model that’s one of the most energy-efficient units in the market today.

Bosch has become a household name since 1886, providing solutions that work for their clients. They offer electric water heaters, along with tankless point-of-use gas-powered systems for a more energy-efficient solution. 

One benefit of the Bosch tankless water heater system is its compact size, making it ideal for small spaces. Although they are significantly smaller than traditional water heaters, it doesn’t mean they are less productive.

Consequently, the highly efficient heat exchangers ensure hot water delivery when you need it, every time. Bosch electric tankless water heaters boast a 98% efficiency rate, with minimal loss, providing the best solution for your home needs.

Most of their models also include low and high-kW settings for customization to ensure optimal use. One benefit of tankless water heaters from Bosch is having cleaner water each time since there is less opportunity to build up sediment.

Another popular choice in the water heater market is Bradford White. For the past 135 years, they continue to manufacture and distribute their units in the United States, ensuring the highest quality possible.

However, this brand is not readily available at stores; you can only find them through authorized wholesalers and representatives. Bradford White has one of the best warranties around for their units.

As long as a certified plumber installs the water heater, you can expect a 10-year warranty with your new model. Their products are a bit more costly than other water heater brands, but the exceptional craftsmanship and reliability make up for the hefty price tag.

In addition, less routine maintenance and repairs make these water heaters more cost-effective in the long run. You can find both electric and gas models in the Bradford White line of water heaters.

They received the 2020 and 2021 Energy Partner of the Year designation for their continued commitment to providing innovative products that save you money and are better for the environment.

Since 1913, Kenmore has prioritized quality and reliability when supplying customers with various home appliances, including water heaters. As a result, the company name has become synonymous with reliability and affordability. Therefore, you can find electric, propane, natural gas, and hybrid models available for your household needs.

One remarkable feature of the Kenmore water heaters is the addition of thicker foam and a higher insulation value. They also include insulated heat traps, making them more energy-efficient by reducing any potential heat loss to a minimum.

Some advantages to some Kenmore water heater models include having two anode rods for better rust resistance, and self-cleaning features to help minimize sediment build-up. These features can save you money in the long run from maintenance and repairs.

If you purchase units with these additional features, you can take advantage of the 12-year warranty that accompanies the water heater. Having a product with an extended warranty can ease your mind regarding potential repairs and maintenance later.

Rheem carries one of the most efficient water heaters available in the market today in their hybrid-electric model. One innovative attribute to a Rheem water heater is having access to Mobile Leak Alerts with some models.

This feature can not only protect your home from potential damage, but it could help you qualify for insurance discounts. Rheem’s Water Heater Booster unit is a popular product that increases capacity up to 45% more without replacing an existing Rheem unit with a larger one.

In addition, this booster includes a Vacation Mode and an Eco Mode, making it extremely energy-efficient, helping save you money each month. Rheem offers an innovative product for homeowners looking at combining their water heater with a boiler unit.

Their Prestige Series takes the features of an energy-efficient water heater and combines it with the functionality of a boiler for space heating in one compact unit.

In addition, they have models ranging from only 6 gallons up to 50 gallons in size, perfect for any size of home. 

The American Water Heater Company manufactures the Whirlpool units under license. They have been one of the leading manufacturers in the United States since 1996, providing high-quality products that are reliable and durable.
