    • excellent product!!
Pattern Name: Water Heater
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 out in the spring it's cold out now (winter 2011). Over all I'm super happy I bought this unit. It's perfect for one guy like me. It saved me a bundle over a regular water heater and install work (this unit was so small and so easy to install) and I'm happy to be participating in environmental/energy savings just by using this unit too. I did void the warranty by installing it myself, I'm kind of a self taught handy man, but I figure the whole unit only cost $250> so I could just buy a new one if anything goes wrong vs some novice electrican ruining stuff and I ended up paying the same amount anyway. If this brand ends up bad, i'll just switch brands. It's the darwin theory for appliances. But every review I've seen on this unit is that it is top notch quality, and when I got it I believe it also the thing is made Awesome, it has a digital dial for the temperature and it simple to install and use. I am so happy I went this route and the 11kw unit is perfect for my simple (one guy) purpose. What that really means is, one sink/shower at a time. At 120 degrees on the dial my showers are Insanely Hot and last forever. I had 3 people in here before (girlfriend and kid) and we all just respected the "showering" person by not using the water. Had to do that with our water heater before anyways. I live in the Seattle area. And MyRubberneck is a good seller too. I got my unit from UPS in about 6 days, the weekend interrupted the (3-5) delivery by a day. That's fine i'm not upset about that though. He saved me about $30 over Sears and their promise was two week delivery for online purchases (ya go check Sears). He sent it in the raw unit box, I kind of wished it had a cardboard sleeve or even a grocery bag sleeve, or bigger box for it. but the box was intact. The Benefits: endless hot water, power bill savings, no more tank pressure/old leaks etc. The Cons: my only complaint is that the warranty is nullified if you install it without a licensed electrician. Oh well. And also the documentation does not say which wire is power, neutral, or ground. The colors were Red, blue, and yellow/green. Ya I figured it out (red+, blue-, and yellow/grn=ground), but dang shouldn't documentation HAVE THAT in there? Maybe it was designed for licensed electricians only. LOL. *Also, an important factor. The water heat temp consistency directly depends on the temperature of the "ground" water coming into the unit. sometimes my shower temperatures got hot or cold (only slightly) but I'm sure it was "cold water sandwiches" but from the ground water temps, especially in winter. The unit is probably taxed to adjust to your preffered temp. Think about that in a "thermal" way. I think if you had a buffer tank or something say (a turned off small water tank 20-30gallons) that had a constant temperature before the unit heated it up then showers would be no problem. My water heater room is totally empty now sans the EcoSmart unit in there, I could put in a buffer tank easy. Or a more powerful EcoSmart unit might make this a non issue. My work around though...just turn up or down the shower dial accordingly, not that big of a deal to me. I give this thing 5 stars!! I get the feeling the big water heater, or power companies don't want people to get their hands on these types of new technologies. It was SUPER hard to find any in the stores that weren't in the thousand dollar range, this was a 1/4 that price. And this had THE BEST reviews from the internet I researched for 10 hours straight, ya I'm a nerd. When I get a real house I will probably buy the EcoSmart 27kw model. I love this unit very much. Take care. ~TZ ... show more

    • Never run out of hot water!
Pattern Name: Water Heater
I originally ordered a tankless gas water heater for our full-time TV but it required far too much space and too many modifications. After much research, I purchased the Ecosmart 11 electric tankless water heater. I was worried that it wouldn't meet our needs, although the specifications indicated it should. It was easy to install and there was ample room in our 5th wheel RV. We have been very pleased with the performance. There are just two of us and we have a washing machine and, although we can't take a shower while the washing machine is running, its no problem to pause the washer when showering. It is so wonderful to never run out of hot water while showering! You could take a 30 minute shower and still not run out of hot water—its great! Since we've only had it for several weeks, I can't speak to the life expectancy, but from other reviews, I'm confident in our Ecosmart water heater. If you are not experienced it working with electricity, you'll probably have to hire an electrician to add the breakers needed and make the connections. ... show more

    • Five stars.
Pattern Name: Water Heater
I'm happy with it for the price. It can heat enough water for our needs . One shower, 2 sinks. Also.. somehow I forgot to drain it . It froze solid after things warmed up a few days later it's still working without any problems.

    • Works for me with some carevats
Pattern Name: Water Heater
Okay, I've had this installed for a month now. This is being used as a backup heater to my solar hot water system so I've had to wait for some really lousy weather to see how well it would work. With a fully depleted solar tank (73 degrees) It will keep up with my shower or any tap. It won't keep up trying to fill a bathtub at full bore but does work if I slow the fill rate down ( I didn't expect it to anyway). Under normal circumstances my solar tank rarely drops below 100 degrees and under those conditions this unit will keep up with nearly any draw I can make. I do have several observations about operation. First, it can take up to a minute to come up to full temperature since it seems to ramp up the power level gradually. water is hot enough to use in about 30 seconds but takes a bit longer to get to full hot. Secondly, although I can set the temperature as high as 140 degrees on the front panel, the unit will not output more than 120 degree water. I even went so far as monitoring the input and output with thermocouples. If my input is more than 120 degrees it will flow though but if the input is below 120 it will only heat to 120 no matter whether the flow is .25 gpm or 2.5 gpm. I sent an e-mail to EcoSmart about this but haven't had a reply. I can set a lower temp and the heater will do that just fine. I installed the unit myself so the warranty is void. I understand the fact that this unit shouldn't be fired up without water flowing through it but it just isn't hard to install a water heater and a 60 amp circuit to power it. It shouldn't void the warranty to self install unless the failure is immediate and caused by poor workmanship. ... show more
