Are Rheem tankless water heaters good?

Many people love their Rheem tankless water heaters. A tankless water heater is one that does not store water but heats water using coils. This makes them impressively energy efficient but also means they provide limited hot water. So keep in mind that they’re best for small-to-medium sized homes.

As for longevity, most tankless water heaters will last you longer than a conventional water heater with a tank. You can get a good 20 years of use out of most Rheem tankless water heaters whereas a conventional water heater might only last you 10-15 years.

How long do Rheem tankless water heaters last?

Ideally, a good tankless water heater should last you 20 years or more. Most of the parts are easily replaceable, and they tend to last significantly longer than storage water heaters. Your self-diagnosing unit will notify you when a part is in need of attention or replacement.

What’s better, tankless or with tank?

Generally speaking, there are arguments that can be made for both. A lot of the tankless water heaters on our list are not recommended for large houses with many family members. However, when it comes to Rheem, they really seem to specialize in tankless heaters. If you have a small to medium sized home and a maximum of 4 people using hot water in your house, many of these Rheem tankless heaters will serve you well.

They’re compact, space-saving, money-saving, and most come with a handy self-diagnostic feature and digital temperature display. If your old water heater is failing, we recommend trying a tankless and having it installed by a professional. Any initial investment should more than pay off within the first year of use.
