Customers say's :
well that was useless...

I bought this thinking it would work for a sink or small shower w/ water saver head on it. Wrong! it won't put out "hot" or even Warm unless the faucet is almost off at .5 gpm(.4 is the min reqd to activate the unit).... What the heck is .5 gpm useful for? I bought it because it is listed as 2.5 gpm. don't go off that. the factory rep told me these are intended for folks in warmer states with warm ground water.But if the water is that warm comeing out of the ground I don't think I would need a HEATER:)
7KW - 240v is alot i can't figure out why it can't keep up with even 1-2 gpm!?! the unit is flawless in it self other than not heating enuf.

Waste of money

This supposedly works for a sink. We remodeled our house, and instead of running hot water to the kitchen, we decided to add a tankless water heater for the sink. Note that we live in South Texas. When the water heater was installed, it was 30' outside. When I tried to use it, I had no hot water. We thought it wasn't working, so we waited for the electrician. That day, it was 60' outside, and we had hot water for approximately 1 second after turning on the faucet. We contacted Rheem, and their response was, we lived in a "too cold" climate! If South Texas is too cold for this thing, I guess only people living at the equator can get hot water out of it! We have another Rheem tankless water heater, but it is gas. It works fine. Just don't waste your money on the electric ones unless you live in an extremely warm climate.

I know why they are called Rheem!

I purchased and installed this water heater in August 2010 in my shop. It worked OK - heated the water OK as long as you didn't run it too fast. I walked into the shop last night and had water all over the floor. The copper housing around the hot water outlet had cracked and water was going everywhere. After I got the water cleaned up, I looked up the warranty and it said 1 year parts, 10 year heat exchanger. So I am thinking that I am covered as the part that cracked is brazed directly to the heat exchanger. When I called Rheem, they told me that was considered a "part", even though it was directly attached and not replaceable without replacing the heat exchanger. There really aren't any parts outside of the heat exchanger.

I guess my only course of action now is the throw the whole thing away and buy another one. I feel like I've gotten "Rheemed" on this deal. Thanks, Rheem.
