Customers say's :
Horrible horrible horrible, over 60% FAIL rate
I have used these units in several buildings. The biggest building being an 8 unit building all with 1 bedroom apartments. Each apartment has it own hot water heater.

We have OVER a 60% fail rate. First you do a LOT of electrical work to get to the point of being able to install it. Then you put it in and this what progresses:

- day one works great and you think "what a great idea I had"...
- few weeks or months later it is hot for a minute, then warm, then cold as it runs
- you reset the unit try and test everything, it works ok you think
- get a call a day later it is the same warm then cold then warm showers
- you take it out and return it to the store.

I have replaced 3 yes THREE in one single apartment alone. All in all I bought 8, for an 8 unit building, and have installed either new or replacements 18, in a eight unit building that only has 8 on any given day, at this time. I am a whiz at getting them in and out...

All Things Considered
I recently bought an AE115 to replace the aging oil burner we have. I actually ended up installing its cousin the AE125.The AE115 was found to be a little on the small side for my geographical area. I hadn't initially known this when I ordered it and I thought maybe I would save someone else a little grief by telling you this. A lot depends on your geographical area. I live in the north east US where my well water gets cold enough to need the larger unit.
You most likely will need to get a few 40 amp breakers if you already have a 200 amp service at your house. I needed to make a total electric upgrade to my house to 200 amps from 100 amps. The AE125 takes THREE 40 amp breakers. Actual amp readings prove to be much less than that and most circuits are protected to 20% over actual use so no need to get to nervous about this. Consider that this amperage is only on for the short time you take a shower .vs hot water heater that is always heating your water(unless you install a...

hmmmm

Works great most of the year. When it is 50 degrees or less, the water tempurature declines. Through the peak of the winter, it's pretty much a cold shower. Customer service is very pleasant and willing to help. They have sent us 2 replacements (the last one was a larger size)at no extra cost to us, but still having the same problem every winter. We are looking into a larger one again. Our house is 2 bath. I still won't ever go back to a tank.
