One of the best advantages to buying a tankless is convenience. The large tank models can often be really difficult to install and control. However, the Rheem RTEX 13 makes controlling your water temperature seriously easy.

The temperature controls go up in 1 degree increments. This allows you to be very specific as to how hot you would like the water to be. You also won’t have to wait around for the water to be heated. It can arrive at your desired temperature when you want it.
Durable Copper Immersion Heating Elements
In order to keep your water hot, the Rheem RTEX 13 utilizes two copper immersion heating elements. No tank is required here, making this a practical choice for smaller spaces, such as an RV.
Water travels through the heating elements, and it quickly becomes hot. This allows you to access perfectly heated water for as long as you want. These copper immersion heating elements are particularly durable, that can lead to a longer life span.
They are also field serviceable and feature self-modulating power control. This is an efficient water heater that gets the job done.
