A.O Smith vs Rheem Water Heater

Rheem and AO Smith are two of the most popular water heater companies in the US. Both offer a wide range of different water heaters for smaller and bigger households and models that are powered both by electricity and gas. But, which one is the best for you?

Generally, AO Smithheaters are the choice of plumbers and can’t be readily found for purchase – you need to go through wholesalers. That said, they are of a very high-quality and should last you a while. AO Smith offers a 10-year warranty on most models, which is unmatched by some rivals. AO Smith also has a very extensive portfolio of heaters and it should be easy to find one that fits your needs best.

Rheem, on the other hand, is available to the general public. They also offer a comprehensive variety of different water heaters and are known to be of very high quality and very practical as well. However, while AO Smith is known for its customer service, Rheem is not. This is very important for water heaters, as you wouldn’t want to be left without warm water for longer than one day.

Overall, AO Smith is probably the better choice, but only by a fraction. You should still be well served by Rheem if you take care of it regularly.
