I tested the AE-9.5. If it worked as advertised, it would be a great little piece of equipment - but it doesn't. It is advertised to achieve an 84 degree rise at .75 gallons per minute. The best that I could do after ten tests was a 70 degree rise. Here are my test results.
Incoming water - 48 degrees
Gallons per minute - .75 GPM
Heated Water Temp - 118 degrees
I did hit 125 degrees or 77 degrees once but not for .75 gallons per minute. For my test, I set the AE-9.5 on a table about 30 inches off the floor. I wired the unit to 240 volts. Actual voltage, 242. The heated water was directed into a two gallon pail using a two foot section of hose. The distance from the unit to the pail was minimized so as not to affect the results. I used a sealed thermometer to measure the water temp. Each test ran for two minutes. I called the Bosch support line for help but it was after hours and they weren't able to answer my questions.

Less than 2 months after installation, this unit will not turn off. It has burst PEX tubing three times due to the overheat condition, and started to smoke and sizzle multiple times. It will *not* turn off even with both in and out water valves closed, and we have to flip the breakers to render it safe. That of course means no hot water -- kind of why we bought the unit to start with. The company is using every excuse in the book to not honor the warranty. They want me to a) hire a technician (at my expense) to troubleshoot the item on site, b) install copper tubing (also at my expense - despite being reminded water hot enough to melt PEX is too hot for skin), c) move the setting to low (meaning lukewarm water), and send them a $100 deposit which upon return of the defective unit, at their discretion, they might refund "if the unit does in fact requires warranty service". An honorable company would send a new unit and an RMA for the defective one, not seek to place blame (however illogical) on the purchaser. Nor should I be required to do field repairs on the pressure switch (or pay a pro) on a $200 item. I am being given the run-around, talking to person after person, and the company is using every possible excuse to wiggle out of honoring their warranty. The unit is unsafe at this point, and represents a fire, flooding, and/or serious scalding risk. A new unit may or may not have these risks, but I can't be sure BECAUSE THE COMPANY WON'T SEND ME ANOTHER ONE despite the unit being only 2 months old and their "troubleshooting" requires *ME* to spend more on technicians than the original purchase price of the unit.

Made only luke warm water at my utility sink 3 foot away. I called and I was told that it was because I had 208 volts. Well, the unit is 240 or 208. Why don't they say it will not work on 208? Would it really work on 240 volt? Not sure, but I dought it would make hot water at all. I'm a electrician (20 years) so I know it was installed properly. I would never buy another one. They would not refund at all. Get a 2,4,6 or 8 gallon tank instead. My 6 gallon works great at the utility sink. Hot water right now. I put a timer on it when I need it the most. Daytime only.

This heater works as advertised! The adjustments for temperature and the 220v hookup should be done by someone comfortable with these tasks - the instructions are not as clear as they could be. The indicator light is very helpful it adjusting the flow as it indicates when the unit is on (there is a click also).

This thing is tiny yet puts out continuous very hot water, just great product. Easy hook up to existing water heater electrical lead and pipes. Gets hot fast and stays hot as long as faucet is on, brilliant.
