An Overview of Rheem Water Heaters’ History

Rheem Manufacturing’s beginnings may be traced back to 1925. They began in obscurity when Richard and Donald Rheem created them, as is typical of many enterprises.

In Emeryville, California, they began working together with a partner. The brothers subsequently acquired that business, Pacific Galvanizing. The Rheem Manufacturing Company started operations in 1930.

After several years of acquisitions, Rheem Manufacturing constructed a facility in Sydney, Australia, in 1936, propelling it to global prominence. They first produced steel shipping containers, but in 1939 they also began producing water heaters.

During World War II, Rheem concentrated much of its efforts on producing shipbuilding and aviation parts. Following the war, they resumed making water tanks, even creating a glass liner for their water heater tank in 1954.

They kept growing their company and product portfolio over the ensuing several decades. They are currently the biggest producers in North America. Additionally, they continue to produce a wide range of goods, such as commercial refrigeration systems, air conditioning, and heating for spas and pools.

Atlanta, Georgia, serves as the company’s headquarters in the United States. Paloma, a water heater manufacturer in Nagoya, Japan, owns the company. The business claims that Rheem Manufacturing is North America’s significant HVAC and water heating equipment provider.

Rheem has other subsidiary businesses outside of the USA where manufacturing and marketing occur. These are only a few nations where Rheem operates and successfully realizes its aim of producing and selling goods for customers worldwide. They comprise:

  • Argentina
  • Australia
  • Chile
  • Iraq
  • New Zealand
  • Saudi Arabia
  • Ukraine
  • Armenia
  • Bahrain
  • Brazil
  • Kuwait
  • Perú Oman
  • Singapore

What is the Rheem water heater’s reliability?

When selecting a water heater, we may consider various criteria, but one of the most important is dependability. For their efficiency and reliability, Rheem water heaters are renowned. In comparison with effective units, they also hold up under inspection.

Examining reviews from confirmed consumers is one technique to determine whether a product is reliable. Finding such reviews for Rheem water heaters may be done in a few different ways. The Home Depot website may be a good place to start if you want to see the precise model you want to buy. Customers may leave reviews and rate the business using a 5-star scale. On the website Consumeraffairs.com, there are more comments available.

As with all internet reviews, you are more likely to encounter a bad review than a favourable one. Customers who have a bad experience are more likely to submit a review. Looking at the evaluations, you may get a better top-down understanding of what to anticipate.

Speaking with a local professional is another approach to confirm a Rheem water heater’s dependability. A network of licensed professionals can recommend and install Rheem water heaters. They know to thoroughly explain what to anticipate when a Rheem water heater is put in your house.

Rheem Water Heaters: How Long Will They Last?

Depending on your water heater, you could anticipate your Rheem water heater to last between 8 and 15 years. The time will be extended if normal maintenance is performed on the water heater and no extraordinary conditions exist. Rheem water heaters can survive 20 years with proper care, and I’ve seen some over 30 years old that are still in operation.

Any water heater’s lifespan varies based on many variables.

Another option is to replace your water heater before its time. If the water heater expires, you might have to wait to return it while taking chilly showers. The water heater can start to leak, causing more damage or, in rare situations, mould growth.

All Rheem water heaters come with a limited warranty, so you should consider replacing the appliance after it has run out. Speak to a contractor at the very least to determine when the water heater must be replaced. They may keep an eye out for offers that allow you to make savings on essential work.

The Rheem tankless water heater is beeping; why?

A Rheem water heater that beeps often indicates a problem has occurred. Clearing the mistake usually requires shutting off the water heater, waiting five minutes, and then turning it back on. If the buzzer continues, a mechanical issue or flushing service has likely happened. For inspection and repair, it is recommended to call a qualified plumber.

When Should Your Water Heater Be Flushed?

To get rid of the sediment inside the tank, storage tank water heaters should have a flushing service done every year. Depending on usage, tankless water heaters must be flushed every three to five years to clean the chambers.


A crucial decision is which sort of water heater you require. When your present water heater breaks down or stops providing the hot water you need, you may have a new Energy Star water heater installed.
