This includes discussing all of its features, its general specs, the pros and cons, and even user opinions to help you have a better understanding about it before you make a decision as to whether or not it’s the tankless water heater you need.
Rheem RTEX 13 Tankless Water Heater Overview
The Rheem RTEX 13 is an electric, tankless water heater designed with the intention to help small homes. Its style is compact, making it provide a small footprint so that you can better install it where you need it to be. This can make the heater especially ideal if you live in an apartment setting, even a studio apartment.
Even though it does run on electricity and does not have a Star Energy rating, it will generally not run up your electric bill considering its size. Adjusting this water heater takes little effort thanks to the external digital control with LED display. In general, it can offer around 4 GPM. However, this rate may go down depending on the temperature. No matter, you can still run an effective amount of water from even a low-grade faucet.
Since it is an electric model, there are a good number of parts required when it comes to installing it. Even so, installation tends to be relatively simple, more so if you have done something like this before. However, in the face of the simplicity, it is still recommended that you have a professional install it. This way, there is no chance of you voiding out your limited warranty.
Additional features about this tankless water heater include self-modulating power control, copper immersion heating elements that are threaded for simple replacement, and a temperature range that goes from 80ºF to 140ºF.
