## Overview

The Rheem 6kW 240V Point of Use Tankless Electric Water Heater delivers instant, continuous hot water with a powerful 6.5 kW heating element and a 1.0 GPM flow rate. Its compact design is 90% smaller than traditional tanks, perfect for under-sink installation. Featuring a push-button ON/OFF control with LED temperature display, it maximizes energy efficiency by only activating when water flows, making it an ideal, professional-grade solution for one or two sinks.

## 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.

Review: Works Great - Excellent Quality - 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.
Review: Love this little water hearter. - 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.

### ⭐ Waste of money. Do not buy this water heater. Worked less than a year.
*by J***D on December 8, 2023*

I purchased the Rheem RETX-06 November 22. I installed it around January in my garage. It is not a high use area so it needed to operate rarely. December 5 the unit would not heat water. The temp readout would blink with the temperature of the incoming water but would not heat. After numerous phone calls with tech support they said the flow meter was bad or plugged. They said they would send me a new flow meter until they found out the warranty expired 2 weeks ago. I purchased a new flow meter from Amazon for $20 and the unit still doesn't work. Save your money and buy a different tankless water heater. FYI Rheem and Ecosmart are the same company.
