Horrible horrible horrible, over 60% FAIL rate
By Johnny V
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.So if you are looking to waste money and a LOT of time as you replace it and try and fix it etc this is for you. These could not even sustain a 1 bedroom with ONE tenant. All my units have a single tenant in them....I did call the company and they are very nice. The guy I was talking with was a technician on what they called the "pro side" for builders professional etc. I explained everything to him and told him of my fail rate and he said that was possible. So they know of the problem, over 60% fail rate did NOT even phase him, he obviously had heard about this plenty of times before me......

All Things Considered
By T. Smith
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 timer). A few more tidbits of info that might be useful. Temperature fluctuations are more noticed than with a water heater but not in the extreme IF you do a little tweaking first. Most people expect no fluctuation right out of the box even though the manufacturer gives you a procedure that will minimize or eliminate this. I adjusted my thermostat and also adjusted the rate or flow of water entering the heater. Are you frugal/cheap? then take a bath and you wont notice it at all. The AE 125 has six elements I think the AE 115 has at least four and they need good filtered/softened or both before the water gets to those elements or you might experience premature element failure due to calcium and other hard minerals in the water. One last thing- check the connections and make sure they are tight. At the factory they are throwing these together and might miss this. A loose connection will eventually cause a failure. All things considered I am very pleased with my heater thus far. It sounds like customer service will work to either replace or repair a unit if there is a problem from other reviews I have read. UPDATE-5/28/2013 I am still using the water heater.My wife takes a shower with water from it every morning. In my earlier review I mentioned temperature fluctuations which others have referred to. I don't notice anything extreme with regard to temperature, even when showering. I did need to tweak the thermostat and you can tell some slight variations when taking a shower, but I guess we are accustomed to that, and the water never goes from cold to hot, more like from warmer to warm. I am of the handy sort and I installed this myself. I know how it works and so maybe I have a slight advantage over someone who must trust a plumber to put one in and set it up. I did find a few things from an installation standpoint that can be bad. You have electricity and water in a very close proximity to one another. One squirt of water on the electronics and its probably over. If you are piping this thing or working on it turn off the water AND the power( a good practice any time). If you get the circuit board wet don't re energize the heater until it is entirely dry. Use a hairdryer...whatever it takes, or wait until it dries. I had an O-ring leak on me last year...a very small leak. I simply obtained an o-ring of the same size, put on silicon lubricant and all is well. These are not easy to replace as it must be seated perfectly and clamped exactly right. When I had it apart I was surprised at how clean it was inside. Nothing on the elements at all!No calcium buildup. Must be because the water doesn't sit around the elements as in a tank water heater. The water flows past the elements only when in use. I have looked at the electrical usage charts for my home. My home uses less electricity than most other similar homes to mine in my area. I have literally saved hundreds of dollars on electricity since 08'. I know a large part of that was this water heater.

hmmmm
By L. Carver
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.
