Heater Performance

rheem electric water heater reviews

Like most reviews mention, this an electric unit, which means it works through a system of internal heat exchangers and sensors, rather than firing up a live flame. One downside to this is that you’ll need to need to install the unit directly above the sink where you want the hot water. But if you’re living in a small apartment, this shouldn’t be a huge issue. 

Flow Rate

As other Rheem RTEX 13 electric water heater reviews were quick to highlight, in addition to its price, the most commendable feature of this model is the flow rate. It has a 4 Gallon per Minute rate, which allows you to run water on a low-graded tap and a shower simultaneously.

With such a flow rate, you’d think that this heater is larger than others in the same price range, however, that simply isn’t the case. What’s more, even if you live in a smallish studio apartment, the RTEX 13 won’t occupy too much space. Another thing that makes it perfect for smaller homes is the source of its power supply.

Heat Flow and Output

One unit can offer water as hot as 100 degrees Fahrenheit. So besides showering and dish-washing, you’ll be able to wash your clothes with this heater. Although the GMP rate goes down with the temperature, flow delays are almost non-existent. Simply put, this isn’t a unit that makes you wait a minute or two for the water to come flowing out of the shower or tap.

Temperature Control

With the RTEX 13, you’ll have complete control over your water temperature. The device allows you to fine-tune the temperature with augmentations of One Fahrenheit. Moreover, the thermostat has an LED display, which allows users to set the temperature effortlessly.


What Makes The RTEX 13 Stands Out?

Energy Efficiency

Thanks to the modulating heat exchanger, the RTEX 13 is very energy-efficient. This part will ensure that there’s no heat loss, which allows the unit to conserve the electric energy. As we mentioned before, since this is an electric unit, you don’t need a venting system to maintain it properly. This also eliminates the emission of greenhouse gases. So if you want a strong but environmentally-friendly unit, this is the right heater for you.

Space Saving

The unit is so small, you can easily keep it under your sink if you want to save up space in your bathroom. What’s more, you can actually keep it anywhere you want – even inside a small cabinet – since it takes up so little space. This is what makes the RTEX 13 so ideal for small homes, studio apartment, and even professional offices and laboratories.

Ease of Use

The temperature control allows you to adjust the temperature without the need to open the unit. Furthermore, the controls are so easy to use, even a young child would be able to grasp them. It has an LED indicator that shows when the heater is in standby mode and when it’s active. While hiring a professional electrician to install the RTEX 13 is recommendable, you can actually do the job yourself in just a few hours. 


Heater Installation

If you want to install the unit on your own, you’ll need some special tools. Depending on the circuitry in your home and the tools you have on hand, you should acquire some of the following supplies:

  • Connectors
  • Conduits
  • Conductor wires
  • Junction Boxes

Despite the need for these supplies, the RTEX 13 is relatively easy to install so you don’t need to be a seasoned electrician to do the job. A professional can install the unit in an hour or so and you can do it in about two hours. We recommend you hire a professional for the job if you don’t want to void your warranty. Nonetheless, if you decide to do the work yourself, you probably won’t face too many difficulties. You can find our list of best electric tankless water heater if this model is too small for you.
