Self modulating flow sensor technology regulates the amount of energy required to heat the water needed. This Smart Technology electric tankless water heater is configured for climates where incoming water temperature can reach as low as 37 Degrees Fahrenheit. The ECO 27 is capable of heating nearly 3 gallons per minute at this temperature. The ECO 27 is the largest electric tankless water heater available with Self Modulating Technology. These models are well suited for homes in the Northern U.S. and Canada and in the southern U.S. that have large Roman-style or Jacuzzi tubs and that have generally more demanding water usage needs.

Rated 5 out of 5 by From Phoenix, This water heater works excellent, I can run two showers and a sink at the same time with no problems, hot water is fast to get to the back bathroom, most of the installation was very easy, the one thing I could not do was the electrical it required 3 new 40 amp breakers and a fair amount of 8 gauge wire (3 of them) all with a positive, neutral, and a ground wire, which then required all to be placed into a 1" piece of conduit, but all in all it only took 2 hours to do the electrical and 20 mins to mount and connect the plumbing, looks great works perfect and I have had no issues. This replaces a 80 gal old school water heater, frees up a lot of garage space and is saving me $$ on my electric bill. I checked out how easy it would be to change out heating elements and looks like it would be simple, (if necessary) (all parts are guarantied for life) Now I have endless hot water and I would highly recommend it to all. I called in because I wanted my 10% retired military discount, they were great to work with. Ltc. Will C. (USA) Phoenix, AZ January 4, 2014
Rated 4 out of 5 by Finally! Unlimited hot water! We ordered this tankless hot water heater when our old water heater had to be replaced. The size of it is very small and compact. We have the entire closet free now. My husband was able to install it with some help. The only issue we encountered at first was that the hot water was not very hot but just regulating the flow through the hot water heater rectified that issue. It does decrease the amount of water coming out to fill up the bathtub but that was the only issue we noticed. February 11, 2014
Rated 5 out of 5 by The system was great for our home. We get heated water throughout our house lightning fast! We are loving it! The product is easy to install and under two hours! March 4, 2014
Rated 4 out of 5 by Ecosmart 27 KW Tankless Water Heater I installed on 1/29/14 and I also replaced my tank heater. In February I purchased the envi r energy monitor with the extra appliance monitors. So I ran the tankless by itself, 3 people living in house (4 but Im on the road all the time) The tankless averaged 12.25 kw hours per day. Ran it for about 3 weeks. Then I turned off tankless and ran the tank alone for about 3 weeks. The tank averages 12.7 kwh per day. So in summary, in my house, it didn't save me money. Without getting technical physics is physics. It takes x amount of energy to heat x amount of water PERIOD. The only bad thing is one cold morning, the heater was running and the dryer. when my daughter went to shower it tripped the breaker (too many amps) I have 200 amp service, but those heat strips pull a lot of amps. Anyway it does what it says (never ending hot water) Pulls lots of amps when in use but of course zero when not used.The only other experiment im going to try is to set tank at lowest temperature and run both together, Maybe it will save me a little bit to keep water at 90 vs 125. and let the tankless heat from 90 to 125 Z(therefore pulling less amps) March 15, 2014
Rated 5 out of 5 by Glad I chose it, even if more changes Tried to fix existing self-cleaning water heater, but new heating coils did not cut it. So, made the decision for an On Demand and chose this one. Required rewiring as more Amps were needed. Then, found out Fuse Box was only 100 Amp, not 200 Amp which was needed, so had to replace that. Also needed to cut tree limbs for higher placed electric wire (thank you electric co-op). Had to put in new elbows and flexible connectors to the On Demand as it had a different placement than 55 gallon water heater. So, after about 5 months of multiple people working on this to get things out, then in, then fitted to, the On Demand is doing great. The 110 degree setting seems too hot for me in summer heat, so I'll lower it iand maybe go back to up in winter. Without the rework time and costs, it would have been the same price as replacing my existing water heater. But, since I am not heating water to keep it at temperature 24/7, but only when I need it for dishes and showers, I'm sure there will be a lower electrical cost effect. Too soon to know what it is. Would recommend to anyone who is capable of thinking outside the box (or tank)! Saves space and I can store more in that room too! July 25, 2014
