The Pros & Cons of the Rheem RTEX 08
Installation and Specifications
The unit’s Use & Care Manual comprehensively informs about the installation procedure. It gets installed fairly easily and quickly. Just mount the heater and an electrical junction box to the area you need to fit it. Plumb the unit into water pipe using the PTC (push to connect) pipe fittings. Flip-off the main breaker and run the 8-gauge wire between the RTE9 and circuit breaker panel and tie it into the junction box using wire-nuts. Lastly, connect the wire to 240V/40amp breaker.

The unit is although being promoted as suitable for large families but in reality it can support no more than two persons at a time. You cannot perform multiple tasks simultaneously such as washing dishes and taking bath, which makes it not suitable for families that demand hot water very frequently. Conversely, response time is very quick and way faster than a gas tankless water heater since a gas unit takes at least 30sec to start warming water whereas RTE9 takes just 15sec. It is an ideal point-of-use application for small family and must be bought if you want to replace gas water heater with an energy efficient electric one.
Definitely go out and get a Rheem RTE 9 electric tankless heater if you live alone and have limited storage space at home. The heater will suffice for your use only and may also support one more person’s needs, but not at the same time. Installation is fairly simple but will cost a little for wiring and pole breakers. If you want to replace your old heater with a new one without too much demand on hot water supply then opt for this one.
