Very Pleased Overall!!!
I have had the Bosch AE 125 since January 2004. Recently I encountered a problem with the cylinders seeping water and loss of hot water altogether.
I contacted BOSCH and as mentioned in other reviews, I experienced the automated answering system and elected to leave my name, phone number and brief message rather than waiting for a rep to answer. I was surprised to receive a call within an hour from a rep and the customer service was superb!!! Still under warranty, They shipped out a new unit to me that day and I received it within 24 hours!
The issue with the cylinders has been addressed by BOSCH and the new unit included the upgraded cylinders which are no longer copper.
Any appliance can encounter problem every now and then, I rate my satisfaction based on customer support when needed and BOSCH has impressed me.
Great Product, I have saved alot of $$$ on my electric bill since I switched to the tankless water heater. I will not go back to a standard water heater.

AE-125 Stay Away
We bought this water heater in the beginning of 2005 the first one didn't work so we returned it for another. That one worked for right at 1 year then quit. I called the tech support and after being on hold for an hour was given an email that showed a diagram on how I could try to fix it. IT didn't work called them back and sat on the phone again for ever and when I finally spoke with someone the told me they would send out a replacement. I was then on the hook for another installation charge. The replacement work for just under 2 years and the water wouldn't get hot so I took the cover off to see if the reset buttons were tripped. One was so I reset it and flipped the breaker back on. The grey plastic box inside the unit lit up and sparks started flying out of it and that didn't stop until I shut the breakers off. So now we are with out hot water and need to buy a new water heater and pay to get it installed. I would tell you to heat water on the stove before you purchase one of these. I gave it a one star rating because there was nothing lower.

We're loving it....
We bought this for use in a 2000 s.f. cabin we are building, and it has lived up to all it's promises. The water comes out of the ground really really cold - we're up north in the mountains, but this gizmo heats it up in an instant. We have enough hot to wash dishes and take a shower at the same time. Just a word of warning - my husband is a do-it-yourselfer and installed it himself, with jsut a little bit of help from an electrician friend. Well, for the first few weeks, we were taking virtually cold showers. I was ready to rip the thing down and send it back. But then we realized we had the power turned all the way down. (We thought it was all the way up - instructions are not clear on this). Even turned all the way down, the water was still a little bit warm. Anyway, we turned it up (slightly) and the water is as hot as can be! We are loving not having to pay to keep a tank of water hot all winter, in a home we won't use until spring.
