While some water heaters supply a decent amount of hot water, Rheem RTEX-13 electric tankless water heater supplies a great amount. But how come? Let’s have a good look at its features and find out!
Energy Savings & Performance
Rheem RTEX-13 is a 99.8% energy efficient unit. This high level of efficiency is reached through its self-modulating heat exchanger. Thanks to this exchanger, heat loss is minimized and a lot of electric energy is conserved. Moreover, since it is a unit that operates by electricity, it requires no venting and no venting means no greenhouse gases. Therefore, we can say that it is a very environment-friendly appliance.
Rheem RTEX-13 has an average flow rate of 3.2 gallons per minute, which makes it perfect for smaller apartments or for your vacation cabin. With this flow rate, it is possible to run a shower and a low flow kitchen sink simultaneously. Although its flow rate is a bit higher than most of the point of use water heaters, due to its price this unit can also be used as a point of use water heater under you garage sink, for example.
With its digital display, it is possible to adjust water temperature in a range of 800 F to 1400 F within increments of 10 F. Since it can heat water over 1000 F, you can use this unit to wash clothes as well as taking a shower.
Design & Installation
What makes Rheem RTEX-13 ideal for your studio apartment or your RV is its light weight and compact size. It is small enough to fit right under your sink or in a small cabinet. Its external thermostat with a digital display showing the outlet temperature and external controls to adjust the temperature make it very easy to use, even for children.
Furthermore, Rheem promises an easy installation process and also an easy replacement. You only need a 3-foot electric cable and 1/2 NPT adapters’ which are included in the unit. Also, ½ inch compression water connections and a 60-amp breaker and you are set to go.
Rheem RTEX-13 has a 5-year primary warranty covering its heating chamber. When it comes to the parts, its warranty is valid for one year, only.

Rheem RTEX-13 Review Wrap Up
Rheem RTEX-13 is perfect for you if you are living in a smaller apartment with one bathroom or if you need hot water in your RV. In case the climate is mild where you live, you can easily use it as a whole house water heating system. However, if you are living in a colder climate where the incoming water temperature is lower, we highly recommend that you use it as a point of use application only; such as under your garage sink.
