Customers say's :
Fabulous ! Saves me $34 / month & pays for the unit & install in 17 months in energy savings
The Rheem RTE “tankless” water heater is ingenious and the energy savings will pay for both the unit & install costs in only 17 months vs. keeping my 50 gallon electric tanked water heater.

I'm a mechanical engineer and was drawn to the unit's energy savings and ultra-compact size (9 x 10 x 5 inches yes inches). You likely won't believe it can provide you the hot water based upon it's small size. Booboo – you're wrong.

Why it works for me:

1. I'm a single person, take 1 shower a day, and do 2-3 loads of laundry a week, plus dishes.
2. I have a low-flow (1.5 GPM) [gallons per minute] water-saver shower head in my bathroom, saving water and also reducing the need to heat larger water flows required by standard shower heads generally at 2 - 2.5 GPM. However, even if you have a standard shower head – this unit will do you fine since it is rated up to 4 GPM.
3. A new tanked water heater (gas or electric) is $400 + $375...

Going green was easier than expected

Rheem RTE 13 Electric Tankless Water Heater, 4 GPM
I just finished installing this water heater in my yoga studio. I have a powder room and an outside shower, with a laundry sink in the garden shed. This heater is amazing. I have it set on "medium" and the water is plenty hot and almost instantaneous. I have used the shower a few times and not run out of hot water. Plenty of volume for my needs. It is about the size of a Webster's dictionary and very easy to mount. Be aware that you need to run at least 3' of copper tubing from both sides of this thing so if you have plastic pipe you will have to make modifications. Also, you need to have enough electric service to handle a 240v, 60A breaker. It says to use 6 ga. wire, but the pigtail on the unit is 8 ga. Use your own judgement here.

Not bad but not the best

I expected a unit of this size to put out hotter water when flowing to a single sink. It's useable but not as good as others I've used. I'd hate to think of what the lower wattage models would do.

It also has the annoying habit of occasionally switching on for a few seconds even when not in use, there's no reason for this to keep the few ounces of water it keeps inside already warmed up.
