Description

The Rheem Performance RTEX-06 is a 6.5 kW tankless electric water heater ideal for point-of-use applications. This unit is ideal for a sink and hard wired to utilize 240 volts. Rheem tankless electric water heaters offer a continuous, endless supply of hot water. A lower kilowatt unit can provide hot water on demand for single or multiple point-of-use applications while a higher kilowatt unit could provide hot water for a whole house depending on the inlet ground water temperature. Tankless electric water heaters save space, save energy, save money, and require no venting. The sleek, compact size, 90 percent smaller than a tank, allows you to save space and place the unit wherever you want, including under a sink. Tankless units only draw energy when hot water is flowing, while traditional tanks are constantly drawing energy to keep the water in the tank at the desired temperature.

    • This will only heat water for a sink or shower with water starting at about 55 to 60 degrees
Style: Water Heater
Installed this heater for a remote bath. The house is in Florida and we are on a well. Water is stored in a tank about 200 gal. to off gas the sulfer, therefore the water is at near ambient temp. This heats the water plenty hot for a shower or to wash up at a sink. Not sure about how long it will work. Right now it works great! ... show more

    • You'll just need to replace it.

Bought 2 of these both failed less than 2 yrs. The flow sensor stops working and there's no way to replace it. Poor design.

    • Installed under kitchen sink
Style: Water Heater
I installed an 8k for my shower and bathroom and love it. I installed this 6k under my kitchen sink. I love my 8k easy to set temp but this 6k you have to remove cover to change settings. I just left to factory settings and gets hot enough for sink and dishwasher. To much of a hassle to get under sink and mess with. ... show more

    • Works but @ very low flow rate.
Style: Water Heater
This is my 2nd time purchasing one of these. I originally installed one of these heaters for a small hand wash sink. It did the job, but was lack luster in performance. I tried one of these a 2nd time, for a different customer for a single sink. The flow rate has to be turned down so low the sink isn't usable. If you turn the flow rate up the heater isn't able to heat the water fast enough so you're left with luke warm just over room temperature water. I ended up removing the unit and going with a larger one. Even the first customer I mentioned I later found out they were unhappy with the heater, but they are keeping it because it is just a shop sink. So 2 for 2 with very poor performance, one of these I had to uninstall and eat the loss. I'll probably never buy of recommend again. They just aren't powerful enough to get enough jot water at a high enough flow rate to make a sink usable. If you are ok with cutting the flow rate down to a trickle then this heater will heat the water burning hot..... but as soon as you increase the flow rate no more hot water. ... show more

    • Works Great - Excellent Quality
Style: Water Heater
Review Image by Amazon Customer
I had a forty gallon water heater go bad at my business. We only have two sinks used for washing hands only, so a big heater was really a huge waste of energy. I had first ordered a Bosch US7-2R, 7.2KW. It quit after only a few days. This Rheem 6KW seems to work just a tad bit slower in warming the water, but I like it much better. I love the display that tells you the temperature of the water leaving the heater and the fact it has an on /off switch. The quality of the cabinet is also much nicer and more ascetically pleasing. The Rheem also came with an electrical pigtail, the Bosch did not. This unit also seems to have much heavier water connection fittings than the Bosch. Overall this is a nice unit for one or two sinks in close proximity. ... show more

    • Love this little water hearter.
Style: Water Heater
My favorite result on this unit is how little room it takes up and just hangs on the wall. Our old standard tank water heater gave out and took up so much space in the laundry room. Easy installation took us less then 30 minutes (we did have all the correct new fittings needed). Takes a little time for the hot water to reach temp and get to the kitchen sink, it's not an instant hot one but does get very hot. The slower you let the faucet run the faster it gets up the temp. All in all it was worth every penny. ... show more

    • Be careful. This one will overheat.
Style: Water Heater
Review Image by In Iowa
This is my second review of this water heater. Initially we liked it. Hot water on demand. We used this one for about a month and were not happy with the temperature control. There is no adjustment to the temperature. If you run the water slow, or shut off the water for even a few seconds, and then turn it back on, the water will get very hot. Many times the water would get so hot that it would start to steam coming out of the faucet. The display showed up to 154 degrees. This is totally unsafe. If we ran the water for another 10-12 seconds or so, it would cool back down. But it was not predictable. My wife hands nearly got burned a couple of times. We've replaced this one from another company that has adjustable temperature and is flow compensated, so it never gets over 120 degrees. ... show more
