Rheem Water Heater Lg

When a water heater breaks and a replacement is needed, most people grab the first one they see on sale. Considering how often we rely on water heaters and the consequences of having one fail unexpectedly, the need for additional research becomes obvious.

Rheem is one of the top water heater brands. With numerous 4 to 5-star ratings on Amazon and Home Depot, and for almost every water heater model they manufacture. After inspecting thousands of Rheem water heaters, we’ve found owners pleased with Rheem products, with many lasting years beyond the warranty expiration. Rheem is no doubt one of the industry’s best water heater brands.

You can buy them at any Home Depot or through a network of independent Rheem pros. Those contractors are well-versed in Rheem and all its capabilities.

Having a quality hot water heater in your home or place of business provides you with more than hot water. It provides you with peace of mind, knowing that your choice of gas or electric water heater will work for you for many years to come.

A Brief History of Rheem Water Heaters

You would have to look back to 1925 to see the start of Rheem Manufacturing. As is the case with many businesses, they had a humble beginning when founded by the Rheem brothers, Richard and Donald.

They got their start with a partner in Emeryville, California. That company, Pacific Galvanizing, was eventually purchased by the brothers. By 1930, The Rheem Manufacturing Company was in business.

Rheem Manufacturing continued to acquire other companies over the next few years and became an international company when it opened a plant in Sydney, Australia, in 1936. At first, they were building steel shipping containers, but they added water heaters to their line of products in 1939.

During WWII, Rheem focused much of its efforts on manufacturing aircraft parts and building ships. After the war, they again went back to manufacturing water tanks, including making a glass lining for their water heater tank in 1954. 

During the next few decades, they continued to expand their business and product line. Today, they are the largest manufacturers in North America. They also continue making many other products, including spa and pool heating, air conditioning, and commercial refrigeration units.

Rheem is headquartered in Atlanta, Georgia, in the United States. Paloma, a Japanese water heater producer, based in Nagoya, Japan, owns the business. According to the company, Rheem Manufacturing is a large supplier of water heating and HVAC equipment in North America.

Rheem has other sub-child companies outside the USA where production and marketing occur. These areas are just some of the countries where Rheem is based and achieve their vision of production and marketing effectively for consumers worldwide. They include:

  • Argentina
  • Australia
  • Chile
  • Iraq

How Reliable are Rheem Water Heaters?

Although we may look at many factors when choosing a water heater, reliability is one of the first things to consider. Rheem water heaters are well known for their performance and reliability. They also stand up to scrutiny when compared with efficient units.

One way to determine the reliability of any product is to look at reviews from verified customers. There are a few ways to find those reviews for Rheem water heaters. One option is to look at the specific model you plan on purchasing on the Home Depot website. They offer a 5-star rating system and comments from customers. You can find additional comments on the website.

As with any reviews posted online, you are more likely to see a negative review than a positive review. Customers tend to be motivated to leave a review when they have a negative experience. Looking at all of the reviews gives you a better top-down view of what to expect.

Another way to verify the reliability of a Rheem water heater is to speak with a local contractor. There is a network of qualified contractors to recommend and install water heaters from Rheem. They have the experience to give you a good overview of what to expect when you have a Rheem water heater installed in your home.

How Long Will a Rheem Water Heater Last?

You can expect your Rheem water heater to last anywhere from 8 to 15 years, depending on your water heater. Longer if the water heater gets routine maintenance and there aren’t any extenuating circumstances. A well-maintained Rheem water heater can last 20 years, and I’ve seen many over 30 years old still in use.

The lifespan of any water heater will vary depending on multiple factors.

Some people also choose to replace their water heater early. If the unit reaches the end of its lifespan, you can be left taking cold showers until you get a new water heater. The water heater could develop a leak, leading to further damage or perhaps a buildup of mold in some cases.

As you will see, there is a limited warranty available on all Rheem water heaters, so you may want to consider replacing the unit when it has expired. At the very least, speak to a contractor to see when the water heater needs to be replaced. They can watch for deals that may help you save money on that necessary work.

Where are Rheem Water Heaters Manufactured?

Rheem Manufacturing has its headquarters in Atlanta, GA, but its water heating products division is in Montgomery, AL. Rheem is an international organization that offers many products, from commercial refrigeration to water heaters.
