Go Green with the EcoSmart ECO 11 Electric Tankless Water Heater

samuel woods: If I could give this 10 stars I would. When I first installed it I hated it. Water would get too hot and I would turn the hot water down and then it was too cold. BIG MISTAKE!!! Now hear me out. lol. Here is the trick that I learned. You turn the hot water on till the pressure is adequate and YOU LEAVE IT ALONE. You then add cold water until the temp is satisfactory. If you need to adjust the temp do so with the cold side only. Do not adjust the hot side. If you turn the hot side pressure up or down the water heater senses the flow rate and will adjust the temp. When the heater senses a pressure drop it will reduce heating. So if the heater has a constant flow rate it will maintain a constant temp. I just ordered another one for my sister. FYI my utility bill dropped by 35 bucks a month

Tutuila G.: I have 2 of these at a small cafe. They work well and I would honestly buy this product when my hot water heater at home dies. It works well and water is really hot at multiple sinks with distance from the water heater. Was easy to instal.

Annony : I bought this water heater at the suggestion of my neighbor, a retired maintenance engineer, who had the same model. It works great once it’s properly installed, but both of us had persistent leaks coming from the left side connector. Plumber tape, goop, etc we’re all tried and failed multiple times, he was so frustrated, but after 5 days of trial and error (and a lot of spilled water) it’s finally working and sealed up. We followed all the instructions. I think it’s a manufacturer defect on that left connector. Otherwise the thing is built really well and solid. Not made with cheap parts. Hope they fix that issue. If I didn’t have a persistent perfectionist helping me with the install, I would have sent it back.

Garrett: Listen I read hundreds of reviews on tons of tankless hot water heaters. This one was the most price friendly but also had the best ratio of good reviews. (We also live in the south so up north I’m not sure if it would be the same due to ground water temps)
It was easy to install. Our old hot water heater wires hooked right up to this new one and we used the same breaker, we just needed $10 worth of new fittings to make our old hoses from our old tank hot water heater fit this new tankless one. We ran our sinks and shower full blast and it had no issues heating. Only thing we noticed was obviously a little less water pressure but our house has pretty low pressure in general. It’s old. Also this thing takes up NO space. The only thing I wish is that we could of hooked ours up closer to our bathroom because ours is located in our outside garage on the other side of our house so we still have to let the shower run for 20/30 seconds to let the room temp water get out of the pipes between the water heater and the shower. This is only the first day we’ve used it. But if anything changes I’ll update. Also I read the manual a million times and stressed about...

Elias Miguel Jaime BarbosaElias Miguel Jaime Barbosa: Bien armado y empaquetado, trae todo lo que necesitas para una instalación de tubería de 1/2 pero trae unas tuercas de cobre para adaptarse, aunque no se mucho de fontanería fue sencillo, bien apretado y ya no hubo fugas. Lo instale dentro de mi lavandería cerca de mi centro de carga, ya contaba con mi voltaje 220 de la CFE en Mx. Compré el cable #6 que se recomienda y un interruptor doble de 60amp también que se recomienda, canaleta de 1pulgada y unos adaptadores para la tubería ya que me agarre de las llaves del fregadero y fue sencillo. Vi varios tutoriales de instalación de boilers eléctricos y no me quedo dudas de la instalación eléctrica, dos fases y una tierra, mi padre y yo lo pusimos, sin problemas y no somos eléctricos mi plomeros. Lo hemos probado con las dos regaderas que son ahorradoras y estan en planta alta, funciona bien, pero no da para más, porque saldría muy poca agua si se abre un lavabo, pero el agua llega caliente. Esperamos que dure mucho, si lo recomiendo para aquellos que no quieren instalar gas natural en su casa, sale practicamente lo mismo que el contrato, mejor instalar esto y te evitas de pagar por dos años.

Jesse: Worked great for about 2-3weeks. Then it started making a humming noise the manual said could be expected. Then it stopped entirely. We are a 3 heated water faucet household with only 2 people. No dishwashers, no laundry machines just two sinks and a bathtub in our little cottage. The demands placed on this were not unreasonable.
The initial contact with the repair technician was helpful and polite, she send me the wires for the temperature regulator and suggested I disconnect the old wires to see if that would work. No children in this house, so it seems safe enough. The heaters continued producing water for approximately 12 hours. Then ice cold. After waiting another 3 weeks for the part to be delivered I installed the new wires and still it didn’t work. I was instructed to use a voltammeter to check the heater. These aren’t your typical house owner requests and I’m fortunate to have an electrician for a neighbour or I would have to be paying a professional their asking wage to accomplish this. They wanted Oms and Voltage. I acquired both and hooked up the old water tank in the meantime to ensure we still had hot water. Upon calling to report my...

Freegon Dave!: Ecosmart 11 works well in Nanaimo, Canada. Our water can get down to 2 C! A must is a water restrictor in the winter!!! 2 gpm is warm... 1.75 nice temp... 1.5 or less hot! and less then 1 gpm really hot!!! Important to have plumber rap 6-10 coats of Teflon tape around water line connections directly on unit; the threading on the bras fitting is milled too much... Space saved is great!!! I'm saving at least $0.20 a day on heating water I don't use. 365 X $0.20 = $73 of wasted heat! Recommend getting larger unit in cold climate. Install cost are going to be expensive... Better to just in stall low flow shower heads etc... I like mine!
Up date: February 2020 I just installed 1 gpm shower head restrictor and they work awesome with the Moen shower wand that was 2 gpm. My thermal imaging camera showed 5C water jumped to 49C at shower head!!! I'm down to $0.12 per ten minute shower now and don't notice a huge difference in water reduction...

Eulalio: Este calentador se conecta a 240v MONOFASICO que no es el voltage que se instala en las casas de Mexico que es de 110v. Los únicos que lo pueden usar, además de casas en Europa y algunos lugares de Asia, son industrias que tienen instalación trifásica de 440v.

StefLeMatStefLeMat: Funciona perfectamente, el agua caliente comienza a salir en menos de 1 minuto.

En casa la distancia entre el calentador y la regadera mas lejana, está a aproximadamente 15 metros. Al abrir la llave de la regadera, en aproximadamente 1 minuto comienza a salir agua caliente. Una vez alcanzada la temperatura, se mantiene totalmente estable. Es sorprendente que un aparato de estas dimensiones proporcione tanta agua caliente en tan poco tiempo, y con tan buen flujo, pues la regadera que menciono es tipo ducha, no es una regadera "ahorradora", y caliente perfectamente.

Ahora bien, todo esta maravilla viene con un precio, y es el consumo eléctrico.

Lo tengo configurado a 35ºC y puedo medir el consumo energético de toda mi red eléctrica. Un baño de 15 minutos consume aproximadamente 1.5 KWh. Si consideras que en México, una casa promedio consume entre 5 y 7 KWh diarios, el consumo de éste calentador es enorme. Estos datos son para finales de febrero, en Guadalajara, Jalisco, en donde la temperatura del agua que se recibe del SIAPA es de alrededor de 20ºC. En tiempos mas fríos el gasto energético consumirá mucho más, en tiempos más...

TripZip: Here's my story review.
I live in a mobile community, one college guy who can't buy a real house. Lived here for 25 years, one day the bathroom looks all wet on the floor, walls stained. The old waterheater sprung a leak and had to go. No floor pan was installed back in the old days so it seems *slaps head*. I shopped around for waterheaters but there were $300< starting price range. I decided to shop around and my main influence is comments (yes like this one) and youtube reviews. Found out tankless ones might save me money. Plus the initial cost was amazing I paid less than $250 for my 11kw EcoSmart unit. I use a drip/drain pan just in case it leaks somehow on the floor. I waited for this review to actually use it for 3 weeks now.

I learned how to solder pipe (easy, fun, use lots of flux!!) to make some small 1/2" thread to 3/4" thread copper shortie pipes to adapt to the unit. I upgraded my circuit breaker to 60 amps dual pole (240v) from 40 amps. I was supposed to upgrade the wires to 8g but I did an infrared heat test on the current wires with hot water running and no heat problems, But I will upgrade the circuit to 8g when it's warmer...
