Questions & Answers

When it says 11 kw, what does that mean - 11 kilowatts per hour?

Asked by: KansasGirl
For some reason, this model is labeled '11' but it is a 13.6 Kw unit. 57 amps times 240 volts equals 13,680 watts.

It says 1 x 60 amp

It says a 1 x 60 amp. Would a 2 x 30 amp work?
Asked by: Specialsnowflake
One 60 amp double pole breaker. Never ever replace a breaker with a higher amperage breaker unless you up-gauge your wiring as well. You would be risking burning down your home.

Is this unit 110 or 240V

Asked by: John
60 amp breaker tells me the unit requires 240 volts
Answered by: reqlbluebaby

Would this model be able to support kitchen/bathroom sink and a washer? Not all running at once.

Asked by: James
I installed this exact same model in a townhouse almost a year ago. The resident has two teenage daughters and they have never ran short on hot water. It is a 3 bedroom 2 bath (with 3 females) and this model handles two showers, the washing machine, and a dishwasher all at the same time. We purposely tested under extreme conditions upon the initial install. You'll be more than happy with this tank-less water heater! In fact, I'm getting ready to remove two traditional water heaters for two separate apartments and install a single tank-less heater.

Customer Reviews

11 kW Self-Modulating Electric Tankless Water Heater is rated 4.0 out of 5 by 80.
Rated 4 out of 5 by from REMEMBER TO TRANSFER THE WASHERS! Would have given 5 stars if not for the instruction omission on the washers. Meaning if you don't turn the caps over to see them you will throw them away. Overall this is a great unit, installed easily and works very well. This is the second eco smart unit I have used (the smaller of the two) but works just as good as its bigger brother. I installed this in an RV with isolation valves to bypass the main 6 Gal gas/Elec std heater. Instructions are simple to understand and follow but REMEMBER TO USE THE WASHERS FROM UNDER THE FACTORY CAPS with the provided conversions fittings. It will leak if you do not. The manual says to not use pipe dope or teflon tape but also does not tell you to transfer the rubber washers. They go between the permanent nipples on the unit and the first conversion fitting to pex or copper. Everything else is self explanatory per the instructions. Happy installing! ~JT

I bought this unit six years ago and it performed flawlessly as a whole house water heater. No doubt paid for itself in electric bill savings in the first year. When the built in flow sensor began to leak, I ordered a replacement from Home Depot. Before it arrived, the EXCELLENT factory support sent a repair / upgrade kit FREE, (Thank you Joe!) also gave me a tip about cleaning the heating elements to improve performance. While I returned the Home Depot order, I will NEVER buy another water tank heater and can't say enough about the engineering savvy and support of Ecosmart.

When our big 65 gal. tank began to fail, we considered going tankless. I bought the ECO-18 only to find that our 100 AMP electrical system could not handle it so we returned it and got the ECO 11 instead. I was skeptical that the smaller unit could handle our hot water needs, but surprise! It works great, even with two showers being used at the same time. Gobs of hot water. However, we are in Florida and the inlet water temperature never falls below 62 F. This may not be the case up north. Love ! Five stars!

Installed in a one bath home in Florida panhandle, produces plenty of hot water. No difference in pressure in the shower going from full hot to full cold (set at 125 degrees). I have had a Bosch 125K BTU gas in my 4br 2.5 bath Michigan home for 10 years and was skeptical if this would be enough heater. As I purchased, I fully expected to be returning for the 18K model (refer to opening statement). Size is hard to discern from pictures, this unit is about the size of a Metropolitan Yellow Pages. Literally, can almost be installed anywhere. Have only had it a few weeks, so cannot speak to longevity.

The unit was relatively easy to install - I was just replacing another brands instant on water heater and needed very little adjustments of the plumbing (which was all pex to begin with). The only difference to the old unit was the screw positions - I had to put a solid piece of plywood to support it. The only issue that I had with the unit is the plumbing adapter didn't fit tightly and I had to apply teflon tape twice to make sure it didn't leak.

After few months of usage one of the heating elements cracked open and exposed its content as black and white sandy substance to the water. Manufacturer refused to provide the new heating elements stating that they are not covered by the warranty. Bought new water heater, after few months - exactly the same story. Not going to buy this brand again and strongly would not recommend it!

Rated 5 out of 5 by from 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 ;-)

I have 1 bathroom and it provided enough water. The only thing i have noticed is that my skin is a little itchy. I believe i need a filter attached to it. Also my breaker fliped, so i may need to update that since it is 20 yrs old. If you have a advice on filter, please let me know. Thank you.
