Rheem 6.5kW 240V Point of Use Thermostatic Tankless Electric Water Heater

I've had several versions of the Rheem point of use tankless water heaters, but this is the first time that I have had to phone Rheem Tech Service for assistance. The directions for electrical connection leave out critical information - How to remove the cover in order to access the connectors. Turns out there are 3 small screws on the water connection side that must be removed in order to remove the cover. Otherwise, works as intended to provide hot water to my laundry utility sink.

This was a breeze to install as long as you know a few tricks. The electric is fed into the case via a 1/2 electrical conduit fitting. To access the wire connections, simply remove the 3 screws on the bottom of the case and lift the cover off. The unit produces good hot water instantly. Very happy with the results.

This unit replaced the same Rheem model number that lasted two years. This direct replacement unit lasted 90 seconds and then shut down.Being a garage sink it was not a high priority to fix. After hours (over several weeks) on the phone with Rheem customer support there was still no resolution. They sent me many pages of Troubleshooting Directions. But nothing helped. Since efforts took so long I’m no longer able to return it.I took the hit financially. Cold water only for the foreseeable future.

Unit works fine and operation is simple.Could benefit from a larger conduit entry - current is 1/2"

Awesome! Had a smaller weaker one, didn't like it. We are using it on one bathroom sink, rated for two sinks, or a low flow shower. Temperature comes up within a second or two, with good modulation to cold. As directed, I ran a dedicated 30 amp, 240v wire (10/3 awg). It only had one ground connector, so I attached both for redundancy, but a 10/2 would have been fine if already present. My install was a very tight fit, I used a thin backer board for the mounting screws.

Easy to install and works perfectly

Hasta el momento presentación buena calidad.

The Rheem packaging states that this device will supply continuous hot water at 0.7gpm for the coldest region in the continental U.S.(and up from there) But the device comes with an aerator which limits the flow to 0.35gpm. and it wouldn't even keep that severely limited flow hot at 105 deg F. in the middle of summer! To one faucet! The Rheem tech support had me perform diags and it passed them all. The unit was performing at its best. They ended up telling me that I needed to purchase a larger unit. This is after I had contracted a licensed plumber re-plumb from a standard water heater. I had to go back to a standard water heater and re-plumb again. After a couple of hours they finally was allowed to speak to a customer service person who, after an hour on the phone, simply said "Sorry" Rheem customer service was pathetic. Needless to say, I will not be purchasing any Rheem products in the future.
