Customers say's :
Dangerous -- No warranty service
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".

14 Degrees Short

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.

15 Minutes to success

My wife reminded me that our children and grandchildren were due to visit our cottage in one week, but not hot water. I placed my order on line and it was delivered in 3 days. Hot water at the cottage in 4 days. Wow it only took me 15 minutes to install. Then hot showers for all on the weekend. Great product.Bosch PowerStar 1.5 GPM Point-Of-Use Indoor Tankless Electric Water Heater #AE9.5
