EcoSmart ECO 11 Electric Tankless Water Heater, 13KW at 240 Volts with Patented Self Modulating Technology

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

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.

It's surprisingly easy to install and works great. I'd anticipated a significant performance loss when switching from a traditional water heater to a tankless model, but this thing is awesome. Instead of using a low flow shower head I went with a pressure enhancing head, the thought being that why should I limit the flow of water before I had the chance to find out exactly what the capability of the heater is. If the heater wasn't capable of keeping up with the flow I could simply turn down the volume of water, and the pressure enhancing shower head would make it tolerable. As it turned out water pressure wasn't a problem. One neat thing about a tankless heater is that you no longer have to use cold water to bring down your hot water temperature to a tolerable level. If I want hot, but not scalp scalding hot, I simply turn the hot tap to full and I'm set. If I want crazy hot I turn the hot water volume down about 20 percent and I'm lobster red in no time. I'm saving money on the electric bill by not preheating water 24 hours a day, and I have unlimited hot water for when I wanna zombie out in the shower. If that's not a win - win I don't know what is.The only real downside to a 220 volt tankless heater is that because it pulls much more current than a standard water heater you will most likely need to upgrade your existing electrical wiring. The paperwork says that it needs 6 gauge wiring, the largest I had on-hand was 8 gauge. For my short wire run it turned out to be plenty. Even after a long shower the wire temp remains perfectly cool to the touch. I also had to upgrade the existing breaker to a 60 amp model. Changing a 220 breaker sounds intimidating, but it's extremely simple. There are only three wires from the water heater to deal with. The red and black wire go to the new breakers wire terminals (doesn't matter which goes to which terminal) and the ground wire goes to a ground lug inside the electrical panel. Study up on the components of your electrical panel and follow basic safety procedures and you'll be fine.The water connections are super simple. The heater comes with a choice of a compression fitting for copper pipe, or a threaded fitting for use with whatever type of plumbing pipe you're using. I used the threaded connector to connect pex piping. If you've never used pex, think plastic bendable water pipe that can be snapped together to whatever configuration you need using press fit connectors. Press fit connectors are also used to connect your new pex to existing copper pipes. Snip snip, click click, and you're good to go. Gone are the days of soldering copper pipes till you're mad at the world. Having installed this unit in just a couple of hours as a newbie, when and if this unit dies I feel confident that I can easily install its replacement in less than thirty minutes. A water heater that will pay for itself in less than a year, AND reduce future headaches? Why the heck not?
