Rated 5.0 out of 5.0 by Timothy580 LOVE IT!!!
I bought this unit for a whole house water heater...
My house uses one wet wall so I bought this unit to replace a leaking water tank... easy to instal and it works great!!! endless hot showers are very nice...
I have already recommended this product to four others including my dad!
I'm not disappointed with this as it does exactly what it says it can do, I do recommend that you read the product info before you buy and buy the right size for what you need... as for my little home, (three bedroom one bath 1400 square feet), the 12KW unit is perfect! I'm now building a towel closet in the space the old hot water tank use to occupy...

Rated 4.0 out of 5.0 by Chronosvandien Good product!!
Bought this unit to replace a leaking standard water heater. Though the product description states only for a single point use, this will supply plenty of hot water for a whole house as long as you only use one point at a time. Works great in my shower and never run out of hot water. Not so good taking a shower and someone using sink. But as long as there is only one thing using hot water it is great. Have not seen my next power bill yet to see the savings but I am sure it will be noticable. Fairly straight forward to install with a little common sense, biggest thing is getting the correct wire to install with. Kind of expensive, but is better to do it right the first time than have any problems later. Buy 6-2 wire as this unit only uses two leads and a ground. I plan on buying a couple more later on to place in my kitchen and other bathroom or maybe a whole house unit, but either way I am very pleased with the functionality of this product.

Rated 4.0 out of 5.0 by QPman Needs a hexagonal 'tightening holder' for the threads, so that the heating pipe doesn't flex as compression fittings go on.
This unit is light years ahead of the old tankless water heating systems. A single heating element makes for enough hot water quickly, and it looks robust. We'll see how it stands the test of time, but for now it works great. The pipe fittings could have been engineered better, as tightening the compression fittings will flex the innards a little as it gets installed.

Rated 4.0 out of 5.0 by JenniferK OK one bathroom water heater
This water heater works pretty good for one bathroom in the south (East Texas) with a low flow shower head. It takes a little time to get used to how to adjust the temperature at the faucet. The installation of the new wiring was difficult. But, the small size has given us a whole new closet that the old water heater was stored in. Also, since we use this just for our guest bath, we no longer have to flip the breaker when people visit to turn on and off the heater. All and all, a good product especially considering the price. When our main water heater breaks, we plan to replace it with the "whole house" version of this water heater.

Rated 1.0 out of 5.0 by woodynla Not exactly the deal it looked like.
Within one month of installation, the board fried because of a direct short in one of the elements. Called the maker and they agreed to replace it after seeing pictures of the fried board. Paid overnight shipping so I wouldn't have to wait for up to two weeks and installed the replacement the next day. Almost six months to the day, the replacement started only giving out a luke warm water supply. Ran some checks and found that two of the elements had no resistance. The elements appear to be the weak point of these heaters.

Rated 5.0 out of 5.0 by patm58 GREAT if you understand how it works
These save a LOT of $ only heat when needed. Should be VERY close to where used. Thermostat helps to give regulated temp after a few sec to minute. First cold, very hot then averages out. We are in FL, coldest H20 is about 69 to 70 degrees. Used for Shower and sink. Installed aprox Feb 2011. Have had other units from this co. They stand behind the warranty and have exelent Tech help. The warranty used to be 5yrs, now it is 2 & 5 IE parts 2 and heater unit 5. Thier website says 1 & 5yrs. so prob changing. The 2/5 was indicated by Home depot.

Rated 5.0 out of 5.0 Great performance!
The AE12 is a great product and performs great within his specifications. It increases my 1gpm cold water flow from about 65F to 120F in seconds. It now allows us to have hot water at every use over 9ft piping instead of the original 80ft of piping witch was not able to provide instant hot water for specific kitchen needs. It is very small and easily fits under your kitchen sink.
The installation is simple but the challenge is to bring a wire #6/2 (50-60 amps) to get the maximum power from the AE12. I paid about $150 for the 6/2 wire and breaker. I probably $200 for the installation by doing myself but took 5-6 hours to go from the electrical box to the kitchen in the center of the house.
Along with the challenge of the wire installation, there are others considerations.
First, the unit has a very thin/weak temperature knob. On my first order, it came broken (it took about 20 days to send back the unit and get the refund). This knob is really weak and you have to be careful not to break it when removing/installing the unit cover. When the cover is installed the knob is safe and can be turn has needed.
Second, the temperature controller does start with a burst of heat and stabilize few second later. So, its tends to send about 10 seconds of very hotter water than requested then finally adjust the desired temperature. This is a programming/designing issue according to me. I would accept a delay of few second not get that hot water than almost burn your hands. But like everything else you get use to it and modify you old habit.
Third, before to buy, evaluate your needs and current specifications like cold water temperature, desire hot water temperature, water flow (gpm), ease and cost of passing the required electrical wire and room to add a 60 amps breaker in your electrical box. It is suggested to look for product specifications and read the online installation manual before to buy.
Overall I like the unit it performs to meet our need. I would buy again! The initial cost is high but confident that I will save at every use now on the lost of hot water of the long original piping.
