Rated 5.0 out of 5.0 by MadMan Works great as a water heater, but a slight issue in some applications
Installed easily, small size fits well, heat setting is dead on accurate as measured at sink or shower, uses switch mode (PWM) triacs to regulate and stage heating elements so uses only the amount of power to regulate temp at any flow rate and does it well. At 11kw max it uses only a little bit more power than a standard tank water heater but only when water is heated, does not come on at random intervals to keep water in a tank hot, so actually uses way less power. The only problem with this and any modern unit of any brand is that the PWM method of controlling the heat elements causes massive amounts of EMI (electromagnetic interference) to be generated, radiated, and fed back up the power lines, so if You are an amateur radio operator You will get noise when someone turns on a hot water valve in the house, and if You use it in an off-grid power system some smart inverters like the Outback series will go crazy because the noise interferes with their CPU clock and power monitoring systems, which are the 2 problems I have. I fixed it by using a seperate dumb inverter to run the heater and prohibit the use of hot water during a QSO on the radio. Problem solved, great device ;-)

Rated 4.0 out of 5.0 by grg Fit a need
We had a small area under the sink and this product fit well and takes up very little room. The installation was not terribly difficult but the wiring requires good knowledge or an electrician. We get good heated water but this does not receive heavy usage and is really just for a sink. This is a first experience with a tankless system and more time is needed for a more substantial evaluation. I would add that most of my experiences with Home Depot personnel are good however no one could give much assistance with this product.

Rated 2.0 out of 5.0 by MrFair Inconsistent and Unreliable
Stability of water temperature is very poor, with constant water flow the temperature would cycle from cold to scalding, necessitating caution and constant adjustment. After about a year the water would not get hot. The outlet thermistor was bad. I contacted the company and I had a big issues with warranty repair because I didn't register the product. They reluctantly gave me two thermistors to replace the ones in the heater. The water heater worked again but the inconsistency remained. Eight months later and the water temperature is barely over 100 F. Bad thermistors AGAIN. Now I have to find new themistors!!! I am done with this product.

If you only have the water running at 25% of volume it will get hot, any more than that it turns cold. Had it for more than 6 months... the store will not help.

Rated 5.0 out of 5.0 by Tito Tankless Water Heater, Is Easy On The Meter
Your ECO Smart Tankless Water Heater has provided me and my family with the necessary comfort we have been used to and at a cheaper cost. The Smart heater has many advantages in addition to its comfort. It has alleviated space in the pump room for me to be able to install our very first filter system. This filter has enable us to use our cistern water for more of the family needs. Now my wife is using the cistern water to cook and prepare our meals. The filtered water, has also replaced the many gallons of bottle water, purchased. Again, this opportunity has presented itself to me and my family because of your decision to provide such quality product HD, Thank You
