Top 3 Rheem electric tankless water heater reviews for April 2024

Rheem is a US-based company founded by two brothers, Richard and Donald, nearly 100 years ago in Emeryville, CA.

The company currently offers heating, cooling, water heating, pool/spa heating, and commercial refrigeration products and is the largest manufacturer of these items in North America.

They have a long history of making high-quality water heaters and have received a number of industry awards for their work. They even sell tankless water heaters under two brands: Rheem and Eemax.

1. Rheem RTGH-95DVLN 9.5 GPM Indoor Direct Vent Tankless Natural Gas Water Heater

No products found.

Rheem’s top-of-the-line model for consumers, the RTGH-95DVLN, is an excellent product for any house replacing an indoor water heater. Homeowners with this model report that hot water flows instantly with almost no lag.

With a flow rate of 9.5 gallons per minute, there’s almost no case where you’ll run out of hot water. It’s powered by cheap, clean-burning natural gas, which makes it energy efficient.

And it’s built using a stainless-steel condensing heat exchanger that is 94% energy efficient – you don’t waste time or money heating anything but water!

Many homeowners even installed the unit themselves. We recommend purchasing the Rheem valve kit for this water heater to make installation even more accessible for those who feel comfortable with this.

And if you’re looking for help on the installation, have no fear. Amazon has an entire marketplace dedicated to finding a qualified plumber to handle the installation at your home.

2. Rheem RTG-84XLN 8.4 GPM Low NOx Outdoor Tankless Natural Gas Water Heater

No products found.

The Rheem RTG-84XLN is similar to the RTGH-95DVLN in many ways. They’re both powered by natural gas. They’re both incredibly energy efficient.

And they’re both constructed with the same high-quality materials and manufacturing standards that Rheem is known for.

The main difference with this model is it is built for the outdoors. This makes it an excellent option for replacing an outdoor heater or trying to free up valuable space in their home or garage.

This model also has a lower flow rate of 8.4 gallons per minute, which is about 12% less than the indoor model.

Still, the US government mandates that a showerhead can have a maximum flow rate of 2.5 gallons per minute, which means this Rheem water heater should be more than enough for most homes.

3. Rheem RTEX-13 240V Heating Chamber Residential

No products found.

The Rheem RTEX-13 is an electric tankless water heater. Unlike the natural gas models above, this water heater has a digital thermostat that controls two copper heating elements used to heat water as it passes through the unit.

The heating element is 99.8% efficient, which is pretty impressive. Installation is as simple as connecting the water lines and plugging the water heater in.

However, electric water heaters do offer a slightly reduced flow rate. This model provides 3.17 gallons per minute, which is less than half of its natural gas-powered cousins.

Even with the reduced flow rate, this should work well for most small to medium-sized homes.

It’s a perfect choice if you happen to have solar panels – using electricity instead of gas for your water heater will lower your monthly bills, meaning this water heater can pay for itself within the first few years.
