Recent reviews of Rheem RTE 9 Electric Tankless Water Heater, 3 GPM:

I bought this Rheem RTE 9 to be used as a point of use water heater in my new bathroom in my “man cave”. I also wanted to run hot water to a hose bib where I could use it for washing the dog, putting hot water in a 5 gal can, etc. Do not be deceived by the 3 GPM ranking. As indicated by the “Use & Care Manual, with Installation information for the Installer” provided with the unit you may be able to only expect a 30 deg F rise in water temp at 3 GPM. My inlet water temp this time of year (January) is 48 Deg F. At 1. 5 GPM I was only to get a 40 Deg F rise in temp. Yup, at half the rated flow I had 240 volts at 40 amps via two 40 amp breakers going in and only 98 deg F water out of the tap. Figured there must be something wrong. After reading the map this is exactly what is to be projected. I started to send it back then started figuring the costs. I spent 166 on this unit, 70 on 30 feet of 8 gauge 2 conductor wire, 8 on a double pole 40 amp breaker, and 65 on miscellaneous conduit, connection boxes, connecters, etc. Just over 300 to install this unit. I can get 166 of this back if I send it back and buy a different/bigger heater with better performance. But, all the lager units require more amps (bigger wire, could have to replace all the new plumbing, wiring and breakers I just installed). So I have decided to buy another RTE 9 and hook them up in series (98 deg water out of 1st unit connects to cold water inlet of second unit) now I have 130 deg water at the tap. This is where I wanted to be but not how I wanted to get there. All in all I received three of these units. The second one I ordered was faulty so a 3rd was sent to replace the second. This unit is nice and small but it is capability to heat water also looks small.

I changed from a 60 gallon natural gas water heater to the Rheem RTE 9 electric tankless water heater. I was worried about it is capability to offer hot water for a family of 5 but so far I’m happy. The answer time for hot water is great, much faster than it was with the gas water heater. With the gas water heater it could take at least 30 seconds for the water to start feeling warm. With the Rheem water heater you start feeling the water warming up in 10 to 15 seconds and it is hot inside 20 seconds. As for showers and baths we have had no problems so far. Part of this may be caused by our use of water saving shower heads and faucets the let between 1 gallon per minute (gpm) to 1. 5 gpm. The Rheem water heater is rated at 3 gpm and it is rare that someone is using more than one sink and the shower simultaneously. For less than 200. 00, you really can not go wrong with the Rheem electric water heater. It most likely took me as long to install the Rheem water heater as it took me to install a regular gas or electric tank water heater. Now I have to wait and see what the difference will be from the gas bill to the electric bill but I am guessing it’ll be less just for the fact that the Rheem water heater only runs when there’s a demand for hot water while the gas tank heater was constantly keeping 60 gallons of water hot 24 hours a day 7 days a week.

I was tired of hasteling my 4-gallon hot water heater in my forty foot RV, I mean 4-gallons of temperate water makes for a real short shower particularly when the winter ground water temperature that is replacing the hot water used from the tank is a freezing 40 degrees cooooold. So I have decided to go with an on demand tankless hot water heater and Rheems RTE9 40-amp breaker 3-gpm hot water heater fit my needs to a Tee. Excellent fast delivery, over the phone they said three to five weeks, oh-well – the RTE9 arrived in five working days, perfect. Installation, it took two to two and a-half hours to install. It took longer to drive to Lowe’s and gather and purchase the parts than it did to install the Rheem RTE9. The Rheem RTE9 was fast and easy to install. I screwed the RTE9 and an electrical connection box to the wall. I plumbed the RTE9 into my RV’s water lines with PTC (push to connect-connector pipe fittings) fast and easy. I flipped-off the major breaker, then ran ten feet of 8-gauge wire between the circuit breaker panel and the RTE9. I tied the RTE9 to the 8 gauge wire in the connection box with wire-nuts and connected the 8 gauge wire to the 240v 40-amp breaker, then I snapped the breaker into the service panel. I opened the hot water faucets, turned the RTE9’s valve on, turned the master RV water shut-off valve on, to purged and prime the RTE9, once they system was loaded/primed I closed the faucets. I flipped-on the major breaker, then switched-on the RTE9’s breaker, the green light came on the RTE9 – and when I opened the hot water kitchen and the bathroom shower faucets again, which are both ten feet away from the RTE9, the red lights came on the RTE9 – and endless hot water came flow’n out of the faucets. What a breeze. What a Great Hot Water Heater. I greatly recommend it for your home, RV or ship ) provided you have a minimum 50-amp service.
