  • We love our little EcoSmart 8...
I would like to point out that we bought an open box version of this through Amazon so I would like to point out a few things if you are looking at those as they are a good amount cheaper than the standard. 1) Just because they say "Like New" doesn't mean that it comes with all of the parts. Ours was missing all the connectors and adaptors. The price was cheap enough that if we had wanted to we could have purchased what we needed from a local hardware store but it would have taken a good chunk of our savings. * 2) If you do get an Amazon open box and it is missing parts your only option through Amazon is to return it, I wish you could just e-mail them and ask for the missing parts. As for the water heater itself, it is a pretty rocking little unit. We live in Phoenix AZ so the water coming into our house is about 70ish degrees, but at that temp this little thing gets our water to 140 at the showers with no problem (We do have low flow shower heads that are about 1 gallon per minute), the kitchen sink sees temps of about 135 and the bath tubs see temps at about 120. Now this will probably not work when winter hits (we are looking to upgrade then and use this one on another project) but our water heater went out and we were looking for a quick solution that we wouldn't have to run new wires for (we had a single circuit 240 with #8 wire so it could handle the breaker upgrade to 40amps). When winter comes and it isn't 160 degrees in the attic I'll run new wires and upgrade with not problem. We were worried that we would have to live with tepid water until a more permanent solution was available but honestly we love this little sucker and kind of hope that our fears that the water temp will drop too much in the winter are unfounded. The thermostat control is great too. With it being an on demand unit, I can lower the water temp to the exact temperature I enjoy for my showers and not even have to fiddle with the cool water at all. * EcoSmart was awesome. When we opened the box and found parts were missing we were able to contact them and they sent out what we needed for free. Unfortunately because it was an open box they can't warranty it (which I completely understand because it was installed by whoever returned it to Amazon in the first place) but they were still willing to work with us to get the unit installed. Great customer service. ... show more

  • So far, it's the best thing since sliced bread!
So far, it's been a great heater! I have an old house, and the electric company only provides 75Amps to my house. With my old heater (11kW), the lights would flicker, as it would chop and suck the line dry (especially when combined with the 15Amps AC working at the same time). The old heater (11kW), would heat the water full power for a fraction of a second, and the remaining time use no power at all. This caused power throttling; led lights and ac capacitor blew quickly. Also, in summer the water was burning hot; no way to control the heat. That's when I knew I needed another heater. This new heater does not flicker the lights. I think it uses a more continuous stream of energy. No chopping frequency, no sucking dry the power line at 10x per second; just one smooth functioning. It also has a temp gauge, and at 100 degrees F, it provides sufficient warm water (slightly warmer than 100F), to take a shower, or wash your hands. 105F gives pretty hot water, only suited for dishes. It's noiseless, turns off immediately when the tap is turned off; and my next electric bill will tell me how efficient it really is! It works great for Florida temps so far; feeding one tap, and one energy saving shower head at the same time. Winter is coming up, and I'll write an update on my review, how it will warm up the water then. ... show more

  • Don't believe the warranty!
I just received the product, and haven't yet installed it. It appears to be well constructed, and it includes adapters for either compression or Pipe thread connections. But here's the rub: There's a big warning on the case, and a sealing sticker that the warranty will be void if the case is opened. Sounds like standard boilerplate, right? ...Until you realize that the mounting screws and plumbing connections are external, but the Electrical conections are internal. The description on the web seems to imply that a power cord is pre-installed, but the unit I received had no power cord, and just a female threaded hole on the bottom for a conduit connector. The actual electrical connections are inside the case, so there is NO WAY that it can be installed without breaking the seal and opening the case. So expect to file a lawsuit if you ever need to make a warranty claim. Hopefully, I will rely on the other good reviews for this unit and trust that I'll never need to do that... It's probably an excellent unit. I chose it because it is the smallest unit on the market that uses a modulating thermostat. I live alone in the country, on a private well, and the fixed on-off thermostat in the Atmor 6.3kw unit I tried drove me crazy with varying output temp as my well pump varied the pressure from 40 to 60psi. I have much better hopes for a comfortable shower without scalding or freezing surprises with this unit. It's also listed as having a .25 or .3 GPM cut-in flow, which is less than the .5gpm of the Atmor unit. I believe that was responsible for some of the chilling 60-degree surprises in the shower as well. So the bottom line is this: Insist on a modulating thermostat if your use case is a shower, or even a handwashing sink with a single-handle control. The simple on-off models would be fine for a non-human use like a dishwasher or washing machine, and probably manageable for kitchen or handwashing with dual-handle controls. But in my opinion, a single-handle control is incompatible with an on-off thermostat because output temp varies inversely with flow rate, so the use of a single-handle control is dangerously non-intuitive. UPDATE: Well, I've had it installed for a day now, and I've used it for a single glorious shower. The temp wasn't absolutely constant, but the variation was well within a safe, comfortable range. I have an energy monitoring datalogger on my electrical supply (OpenCMS), and a review of the energy use during my shower showed a clear repeated sawtooth pattern as the well pump kicked the pressure up to 60psi, then fell slowly to 40psi. The difference in flow was not obviously apparent in the shower, but clearly the sensors in the ecosmart unit responded quickly and appropriately to the changing conditions. There's one other grmbl I should mention. Not only are the electrical connections located inside the unit, so voiding the warranty is a necessary pre-condition to installing the unit, but the 'Earthing' Green screw is located UNDERNEATH the central thermostat control and display. Not only that, but it's much too small for the 8GA wire that the code requires in this area. I was forced to remove four additional screws so I could lay the thermostat assembly to the side to make the connections, and find a crimp-on fork connector for the wire. That was non-trivial in itself. It's not common to connect an 8GA wire to a #6 or #8 stud, so every one I had on hand was either too small for the wire, or too big for the stud. Is it too much to ask to design it with a three-terminal block instead of a two-terminal block and a tiny hidden screw? How much would that cut into your profit margin? Back to the plus side... The internal plumbing parts appear to be stainless steel, and the inlet and outlet temp sensors are actually inside the water flow. That's probably responsible for the fast response and small variation in temp control. On the other unit, the internal parts were plastic, and the single temp sensor was just zip-tied to the outside of the heater chamber. The insulation value and thermal mass of that plastic I'm sure contributed to the wide temp swings and scalding surprises. Bottom line: This EcoSmart 8 appears to be mostly well designed and constructed, so I'm expecting a good service life from it. It was the only model I could find that has a modulating thermostat and would run on a single 40Amp breaker. (Did I mention I live in a mobile home with a 50Amp main supply?) Oh, one other thing: Both inlet and outlet connectors are near the top of the case, and there is no gravity drain provided at the bottom. So avoid this unit if your use case is a seasonal summer home and you need to drain in the fall for winter freeze protection. With this unit, you'd need to use an air compressor to blow out the unit, and even then, it would only be effective if you applied the air pressure backwards, from the outlet side. ... show more
