Top Amazon Reviews
To preface, this is being written by a 30 year old woman, a total girly-girl, though I don't mind getting my hands a little dirty if it means saving a TON of money. My husband and I did this project in half a day. We just lost a 2 year old tank heater due to our sewer backing up, and we didn't want to risk another one, since they can't be used once flooded. We decided on a tankless after reading a lot of reviews. Pricing them locally, they were anywhere from $650 to $2,000 with decent reviews. I found this one on Amazon as well as Sears and a couple other online places with 5 stars on every site. The price fluctuated a lot, but never went over $500. I bought it for $438. This heater is nice and compact. It is 17" on the longest side, and only weighs 11 pounds. Coming right out of the box, I was impressed with how small it was! The packaging from the factory was good, but one corner mount was a little bent and the plastic knob fell off. We had to build a small wall to mount it on in our 120 year old basement. Just a couple of 2x4's mounted to the ceiling and it went right up! Mounting it was incredibly easy. I could hold it up with one hand and mark the holes, then leveled it and screwed it right in. The bent corner flattened right out. Using flexible water heater hoses from our local hardware store, I was able to attach the plumbing to the new heater from the old connections in just a couple of minutes. When I first took the covers off the bottom of the heater, a little bit of water leaked out, but after asking around, I'm told that is normal from the pressure testing they do in the factory. Running the electric was the most complicated part of the process. Our main breaker is 150, and though the manufacturer recommends 200, the 150 is sufficient. We were fortunate that our box had plenty of space for the 3 double-pole breakers. The wire required is very thick and heavy, and was a little hard to work with. We ran three lines from the heater to the breaker box. Installing the wire in the heater was simple. The instructions only say to hire a professional electrician. Really, you just run the wires through the bottom, put each one in the electrical panel, connect the ground, and you are done! Connect the breakers, and wallah! You have a water heater! We initially set the temp at 115 degrees, but dropped it down to 110 and it is perfect. It does take a little bit longer for the hot water to reach the shower or sink, but once it does, it stays hot, and stays consistent. Our shower head has a flow rate of 2.5 gpm, and it stayed nice and hot! My husband, son, and I all took hot showers and it was amazing to not have to wait in between! The instructions recommend setting the water heater at the hottest temp preferred for showers, with the idea that you only turn on the hot water and don't need to mix in cold. This is brilliant! So far we are very, very pleased, and love that we don't have to worry about a backed up sewer ruining our investment. The project took about 3 hours total with 2 people working on it to install. We were able to do it with all the normal tools we had laying around the house. Our cost for supplies was around $300. It would have been less but my husband cut one of the wires too long, which made the third one too short, so we had to buy an extra $40 25' wire in addition to the $95 75' one we initially bought. We needed the following: -wire -3 40amp double-pole breakers -2 conduits for the breaker box -2 flexible water heater hoses -adapters for the hoses from where we had to cut the pipes off the old water heater, primer and glue to connect them -plastic holders to nail the wire to the rafters That's it! The wire was the most expensive part after the water heater. The hoses were about $13 a piece, and the rest were just a couple of bucks. I'll update after we've used it for a while! ***1 YEAR UPDATE*** It's been a year since we installed our electric tankless water heater, and could not be happier! It does take a little bit longer for the hot water to reach our faucets, but when it does, it is unlimited and stays nice and hot. We can run 4 showers or baths and do a sink full of dishes, all after running a load of laundry, and still have hot water. Our gas and electric bills come as one, and we have not noticed any difference in our bill compared to previous years, switching from a gas tank heater to an electric water heater. I think the fact that we are only heating and using the tank "on demand" vs. having a gas tank that constantly heats, is why. I still recommend this tankless heater to everyone that will listen!

I've had this for 10 months (updated: 2 years now) and it's worked great. I have really high powered water pressure in the showers here, and sometimes also am running a laundry washer and sink. I tried running the washer on Hot, then I turned on 1 sink and both showers to very hot and they all had plenty of hot water. It was pretty easy to set up. While their disclaimer says that you need to have a licensed electrician install it to get the warranty, over the phone 2 people there explained that it's fine for a handyman to set it up, and that they will still honor the warranty as long as the problem clearly is not due to bad installation. In other words, if the problem is due to poor installation, then obviously they won't want to send you a new one. That's more than fair and means that you can save a lot of money having your handyman do it if he has electrical experience. I spoke to some people who said that most companies will put that a licensed person is required to install it for liability purposes to protect themselves. In real life, Ecosmart will cover it even if a non-licensed person installs it. Just write their name and phone number on the warranty registration card and send it in. Also, though their site says (I think from memory) that it needs 120 amps total, we asked them if putting it on a 100 amp subpanel would be enough, and they said yes, and we did that and it's fine. I was told by a number of people that if you put it on a 100 amp subpanel and for some reason it gets more than 100 amps, all it does is switch the subpanel off. That's the point of a subpanel. It makes it so only 100 amps can reach your main panel. So even with 2 showers, a large washer and a sink going, it didn't go over 100 amps. And my showers have great water pressure, so it probably would be like 3 showers in most houses. I only have 150 amps total, and everything has worked great. I found customer service great to work with. If you have a tech question, ask them if you can speak to one of their technical people. They were happy to help me figure it out. The price for this was much lower than other places I researched, and not much more than a tank. I've saved a lot of money on my energy bills as it only heats up water when you need it. I think the savings will pay for the difference in 1 year, and after that it's extra money in my pocket every month. I believe Amazon was a little cheaper than getting it directly through them but check because that could change over time of course. Also, it doesn't take more than about 10 seconds longer to get hot water than with my tank. With a tank, the water in your pipes cools off, so 90% of the wait for hot water is the old water running out. I used to have to wait about 1 minute to get hot water in my showers. With this unit, it adds only 10 seconds to the process as it quickly cranks up and starts heating the water flowing through it. For the occasional mindless person who claims that because their one unit was a dud, that all of them are - get a brain and learn some math. If you buy 40 units and 10% of them are duds, then you can make some claims about overall performance. If you go to any tank or tankless heater that has more than 80 reviews, you'll find at least a couple of reviews by people who got duds. It doesn't mean they all suck. Be honest and just say, "Mine broke and I was unhappy," and don't try to make up that everyone is going to have a problem because you did. In this day and age, pretty much all manufactured things have some duds, even high end computers like Apple. I got a dud iphone and had to have it sent back for a new one. Does that mean you will? Chances are low. I have another property where I still have a tank, and just as many things can go wrong with a tank as with a tankless. And when they go wrong with a tank, it can wreck the floor of whatever room it's in or close to, along with whatever things (furniture, cabinets etc.) are in touch with the floor. I can't wait to replace the tank with a tankless. When the time comes, I'll research what the best buy is out there for price and performance. Ecosmart was when I did, but I'm not wed to them or any other company. I also regained half a closet as it takes up almost no space. I put it in the upper corner of a closet out of the way. You can set the water temp with the turn of a knob. I love it. I will never go back to a tank. UPDATE: I've had it for 2 years now and still super happy with it.

I purchased the Ecosmart water heater to put into my new home that I built last year. I hired a plumber to do all of the new plumbing work so plumbed it in for me, I did the electrical work myself. I ended up spending about $180 on wire and breakers. The ECO 27 requires 3-30amp breakers at the panel and 3 runs of 8 gauge, 2 conductor wire. I live in Canada and 8/2 wire is rare apparently, so I had to go with an 8/3 wire and simply didn't use the third wire, and taped it off. The electrical installation was pretty simple, I followed the directions, watched their YouTube installation video, ran through the tests with my tester, and viola, hot water. My complaints. The water takes awhile to get hot for some reason. I don't know why. It seems as if all the cold water in the lines has to disappear first, then be replaced with hot water, then the hot water starts to come out. Washing your hands in the bathroom sink or kitchen sink can be slightly frustrating, as you have to wait a bit before the water gets hot. This is different from how I remember the way a hot water tank works. That's it. On to the good stuff. First things first, the shower. In my master bath I have two shower heads in the shower. A Delta 57014 Slide Bar and an American Standard 10" Rain Head. I installed a diverter so I can use one or the other, or both. I had to tweak the temperature settings a little bit, at first I figured 105 degrees would be best, as I enjoy a nice hot shower. However it was a bit too cool, perhaps the distance the water had to travel cooled it down? So I stepped it up a bit to 128 degrees. With a single shower head running it is right on the edge of being too hot, but I really enjoy hot showers. If it becomes too much for me to bare I turn it down a little or just flip on the other shower head. With both running, it is a temperature I think most people would enjoy. I try, most of the time, to be energy and water efficient, I turn the shower off and soap up, turn it back on to rinse. But let me tell you! I've had a couple of mornings after being out late and having a couple too many drinks, and I have laid in the shower with both shower heads going for upwards of an hour. It doesn't stop, it doesn't slow down, it doesn't get cold. Even when it was -20 Celsius outside, it kept heating my water up for my shower :) The last thing I would like to say about the shower, since I have the Ecosmart set at a temperature that works for me, all I do is turn it straight to hot, no mixing. This allows toilets to be flushed, sinks to be ran, etc. without ever flinching a degree when I am in the shower. Next! I installed a Roman style faucet for my tub. This baby pours water out. It pours too fast actually. The Ecosmart cannot keep up. This was actually the first test I made with the water heater and I was very disappointed at first. However, if I turn the tap down a bit, it heats up, turn it down a bit more, and it gets even hotter. Simple fix really. The tub takes a little longer to fill, but it's not a huge deal. I don't bathe often anyway. The dishwasher.. I have a Whirlpool dishwasher that has an element in it to help heat the water beyond what the Ecosmart can do. I never had any problems with washing dishes, I'm not 100% sure how well it would perform without the element in the dishwasher to help heat the water more, but I purposely bought a dishwasher that would do this just in case. All in all, it's an excellent and aesthetically appealing unit. I don't have any complaints, and it seems as if it's only limitation is at higher flow rates. I cannot say if it's saving me any money, as I haven't anything to compare it to.

DO NOT BUY ECO 27 - THIS IS JUNK!! After talking to the company and doing some research (apparently not enough) this unit makes all my LED's lights inside and outside my home blink rapidly on and off. And if you are able to get customer service on the phone, each person has a different opinion of how to fix the problem. While building my new garage I had my electrical service upgraded to a 200amp service. At that time I also had installed the required 3 double pole 40amp breakers and all the new required wiring to replace the old outdated On Demand water heater with the new ECO27 On Demand Water Heater. The install instructions were followed, step by step, I know I oversaw the whole install. OK, I thought everything was good to go. Well that night as I tried to wash a few dishes by hand, my island kitchen lights were blinking like crazy every time I turned on the hot water. To make matters worse as I ran the water in the shower, by bathroom lights also were blinking; along with my outside security lights. I talking really blinking, non-stop the whole time the hot water is running. I called the electrician he came out checked everything out and suggested I call the local Power Company and have them check out the line coming into my home. I called Duke Energy, told them about the light blinking problem, they came out did some tests and said everything was working and the right amperage was coming into my home. After much trying and a few days, I was finally able to get ECO tech support and the installer on the phone at the same time. It was suggested that maybe one of the 40 amp breakers were bad. So all 3 breakers were replaced and everything was tested again, same problem blinking lights! After several tries and very long hold times (at least 30 to 45 minuets) I was able to get tech support on the phone again. After more testing and a lot of the same tests from the previous tech support guy, it was determined that they would send out a new unit. This was done on my part by filling forms, faxing forms, putting up deposits on my credit card, having the Eco Smart 27 uninstalled, boxing it up and sending it back. The new unit arrived; again I paid to now have this replacement Eco Smart 27 installed. Everything was tested and again the blinking lights! I have actually gotten to the point of turning off lights when I do dishes or run the hot water for anything. I now try to complete everything that requires hot water when I get home from a long work day before sunset, cooking, dishes, laundry, showers ect. I guess that is the way ECO Smart saves money on the electric bill; no hot is used after dark. OK so I have had enough of this blinking light craziness! I again have my entire house checked out switches, plugs, fixtures, ect. Everything is good to go with my home. I was also told that continual blinking lights were not good for the fixtures or the wiring in my home. Scary! So I contact ECO Smart customer service to find out if they have a fix for the blinking lights? I am told by a very rude tech support man that I need to replace all the ballasts in every light fixture in my home including lamps! I think I actually asked him if he was crazy. At that point I requested a refund for the Defective ECO Smart 27. I was told that their company did not give refunds! And that there was nothing wrong with the water heater. I hung up and called back to ask for a company supervisor, again on hold, this time I got a woman who seemed annoyed that she was forwarded my call. She did however say that she would look into it and she or someone else would call me back. I did received a call back from customer service; the customer service guy had me do a few DUMB tests, exemple: reduce the heater temperature to 105, turn on the hot water? Yes the lights still blink, ect When he could clearly see that the ECO 27 was the problem, he then tried to tell me that is was probably the dimmer switches I had in my house. And said I would need to contact the manufacture to find out if the switch's LED setting were properly set on the back of each switch. I told him that I knew for fact they were correctly set as I had talked with the electrician about this setting when they were installed last year. At that point he said then it was probably the transformer from the Power Company and I would need to call them. I told him that had already been done and everything checked out fine. At his point, he said he would have to check call the Power Company himself to see if the right tests had been done! Really! But OK. Up date: I again had to fax in my Paid Receipt, (second time) and did not receive the promised 4pm call back yesterday. Today when I called the customer service guy, (after all he didn't call me back and at this point I would just like a refund on this defective water heater) I was told that now he would have speak to the installer? ECO has already spoken to the installer several times? The customer service guy also told me that I would have to try to get a refund back from Amazon? But this ECO 27 came from their company not Amazon. The Amazon ECO 27 was returned to the ECO Smart Company. I feel it is just more run around!!! BOTTOM LINE --- JUNK,, BUYER BEWARE!!!!

My electric tank-type water heater developed a leak, and after a lot of reading on the Internet I decided to replace it with a tankless unit from EcoSmart. I'm fairly handy, so I wanted to do the work myself. I bought the heater from Amazon for $453 and various electrical and plumbing supplies from Lowes and Home Depot for $251, for a total outlay of $704. Aside from the tankless unit, the biggest expense was the wire. Tearing out the old tank heater was easy and only took about a half hour. Mounting the EcoSmart unit in the same place as the old heater and creating the new plumbing connections with copper pipe took about 4 hours. Although 240-volt wiring was left over from the old heater, the 12-gauge wire was too thin, and there was only one 30-amp circuit available. The EcoSmart unit I bought needs three 40-amp circuits and 8-gauge wire. My breaker box is located about 30 feet away from the water heater location, so I had to string 3 lengths of 8-gauge, 2-conductor wire up into the ceiling and across to the breaker box. This took a full day, and crawling around in the space above the ceiling killed my knees. My electrical service is 200 amps, so I only had to find 3 double-wide slots for the new circuit breakers (one slot where the old water heater connected, and two new slots). Shuffling a few breakers around gained me the last 3 available slots. Hooking up the EcoSmart unit was simple, and the instructions are very clear. The biggest hassle was routing the heavy 8-gauge wire into the breaker box. Doing the electrical hookup took about 3 hours. After verifying that nothing leaked and all the voltages were right, I turned on a hot water tap and prepared for the worst. And Voila! Hot water. Lots of hot water. After playing with the EcoSmart unit for several hours, I have the following observations: 1. It works, pretty much as advertised. Owing to electrical power limitations, it can't produce super-hot water at high flow rates, but it has no trouble producing really hot water at low flow rates. This means that it's advisable to install low-flow heads if you like hot showers. I doubt if the EcoSmart unit can keep up with multiple showers running simultaneously, despite what they claim, but for most tasks it should be fine. The only operational quirk I've noticed is that the water temperature is initially fairly hot, then not so hot for a few seconds, then hot again forever. 2. The EcoSmart unit is well made. When and if they fail, the heating elements will be easy to replace using standard, off-the-shelf elements. The innards of the unit are nicely laid out and constructed using first-rate materials. And you can't beat the lifetime warranty. 3. The project is well within the scope of a do-it-yourselfer with decent plumbing and electrical skills. The biggest hassle is running the heavy wire, and you can expect the job to take two days if you're replacing an electric tank-style unit. The installation instructions are crystal-clear, and the troubleshooting guide is very good. Make sure you have sufficient electrical service (200 amps) and space in your breaker box for the additional breakers (or add a small sub-panel). Finally, be sure to take into account the cost of the additional plumbing and electrical stuff you'll need. The bottom line is that I'm pleased with the EcoSmart tankless water heater. Installing it was a somewhat bigger hassle than I had anticipated, but it all worked out in the end. Its only apparent limitation is an inability to produce piping hot water at high flow rates. We'll see how much money I save as time goes on.

Reason(s) for purchase: 1. Save $ on energy cost 2. Our tank water heater wasn't getting the water hot enough (could have been going out or was adjusted IDK) 3. Free up some valuable real estate in our laundry room (more like a closet) So, I managed to buy this model for $360 brand new. I had originally paid $505 and was on amazon about a week later and noticed that this product was on sale as Amazon's deal of the day. Sent the other one back and bought the sale one lol. I decided to go with this particular model because I would much rather have too much than not enough. It's all about the incoming temperature and living in Hawaii this product should do the job for us (4bd 3bth).I will update on actual savings in $ but keep in mind that each state charges different amounts per kWh (Hawaii charges x3 of the national avg. so savings may appear more drastic) and families use different amounts of hot water, but at least it will give you an idea. Pros: -Unlimited hot water -Supposed to save $ on energy -Frees up valuable space -Looks Modern Cons: -Initial cost may be more than tank (will recoup $ over time) -In order to keep warranty must be installed professionally -Requires three 40 amp double pole breakers -Most likely need new electrical wiring ran -Seems to take a bit longer for hot water Install: Install "can" be fairly simple for the average DIYer if you can follow instructions and a few safety guidelines. The hardest part is running the wiring to the electrical panel. Everything else is pretty easy. If your breaker box is in the same room as your plumbing the install should be cake. Just make sure that your work is done to code. Wife and I installed it together (she helped run the electrical wiring to the breaker box). Ours was across the room in the hallway. It actually took us two days working a couple of hours to run our electrical (a different story for another day). After running the electrical it probably took me 30 minutes to an hour to finish the rest (installing breakers, mounting and wiring the heater) After use: We have only been using it for about 3 or 4 days now and it is going to take some getting use to. The water definitely gets hotter than it did before. The hotter water was the first thing that the wife noticed, but it does seem to take a bit longer to get hot water to the faucets. Not a lot of extra time but it's noticeable, but other than that I have no complaints. That's not even a complaint..... More of an observation. Bottom line: I plan on installing one of these in our next home. I recommend this product to any who is debating whether or not to buy a tankless water heater. Just do your research and makes sure that it will fit your needs. My wife regretted this purchase after having to bust holes in our walls/ceiling and realizing how much work it was for us. Now that it's done she tells me all of the time that she is glad that we installed our new tankless water heater. Plus it does everything that we wanted it to do. Update: Product is still working flawlessly and I haven't noticed any light flickering at all. Plus I am running this on a 150 amp service, but my incoming temperature will always be 60-70 degrees F all year round so shouldn't come close to maxing this thing out. After 1 1/2 months of service this is what I noticed: 1. Saved $14 on first full electric bill 2. Almost seems like a waste whenever I wash my hands because by the time the water gets hot I am long gone unless hot water is already in the lines (not the machines fought). I thought about purchasing some point of use heater but changed my mind (not my forever house) 3. Love the bit of extra space in the laundry room. Feels more like a laundry room now that we can actually fit some clothes baskets in there. 4. Wife still enjoys it quite a bit. We even turned it down to 115 degrees. I was hoping to save more per month but even at this rate it would pay itself off in about 4 years or so (including everything....wiring, drywall to patch, texture, paint, valves and filter= Roughly $600 ). Not bad....Hoping next month we notice more savings. Will see I guess. Either way this product performs as advertised. Highly satisfied.

I love this tankless water unit! I've been using it for 2 years now, and I am single. It has some quirks, but is well worth the time and money to install. You can adjust the water from 108 I believe to 140 degrees. I keep it at 125 because I don't want to scold my little grandsons when they are bathing. Young ones like to fiddle with the water faucets and this feature was important for me. Installation was easy to follow and easy to do. I plumbed and ran electrical by myself and it was easy to do for somebody with moderate experience. You will void the warranty if you don't have a certified electrician and plumber install this unit. But for the extra money that would have cost, I could buy another 1 or two units easily. I decided to take the risk and do it myself. How does it work? Just great. The temperature is usually stable and kicks right in. Every 4 or 5 months I will have a situation where it starts off hot and backs away to lukewarm. I don't know what causes this, but I believe it is just a momentary issue with the temp sensors adjusting to the water flow and temperature of incoming water. Pay close attention to your average ground water temperature when you are choosing your unit. That's important, and especially so in winter when your unit is going to work the hardest to keep up. Sometimes it takes a few mins to really reach the highest temperature, but that doesn't bother me at all. With it set at 125 degrees, I just turn it on hot and leave it there to shower - for as long as I dang well please lol. That is the best feature of this unit. I don't take super long showers but I like to know the tank won't run out on me if I'm soaped up. My house is on a pad and the pipes run through the concrete. I live in Kansas where the winters get cold. The bathroom that is farthest from the water heater always takes the longest to get water to the shower and faucet. So you have to calculate that when taking a shower. If I run a bath in that bathroom, the amount of water coming out of the faucet is big enough that hot water reaches that faucet very quickly. But the separate shower and sink takes much longer because a smaller volume of water is flowing. If you are one of those families who has constantly circulating hot water so you never have to wait for hot water when you turn on a faucet, I am questioning why you don't just hire an architect to design a Roman Bath for you replete with slaves and belly dancers. You are not going to be happy with this unit. You have to wait for the good hot water to come to you. Or at least I would consult with a plumber to get a unit that is suitable for your needs. Take the time to be realistic about how much hot water you want at any given time. If your family can't wait to bathe one after the other, make sure the GPM flow is good enough. If you need to run water in the kitchen, water in the laundry room, and water in 3 bathrooms at the same time, be sure to take the time to measure each faucet GPM so you can be happy with the unit you are purchasing. I highly recommend this model and this brand!!!!

Update August 2023: After 10+ years of flawless service the heater finally had a problem! The first element closest to the cold water inlet failed - it cracked and shorted out. Device continues to work fine but capacity is reduced. I decided to buy a new one instead in case of any manufacturing improvements over the years and keep this one as a spare or for parts. I had never flushed it or cleaned the elements in vinegar in 10 years and I was surprised how pristine everything was inside in spite of our South Florida water! The only debris was from the cracked element and some light yellow calcification paste - the other two elements looked like they just came out of the factory! No pun intended but this tankless water heater is built like a tank! Original Review April 2013: I put in a SETS 24 tankless 120AMP electric water heater about 6 years that finally gave up the ghost last week The company was out of business so I was not looking forward to major wiring or plumbing changes with a new brand. I selected this EcoSmart 27 based on the amazon reviews and I was very surprised that it was a perfect drop in replacement for my old heater w/o having to do any plumbing or electric changes! It requires 120 Amp service with 3 double pole 40 amp breakers same as my old SETS. The inlet and outlet pipes location and spacing are identical to the SETS so I didn't need to change any plumbing. Having used tankless electric heaters now for 6 years, the technology has changed tremendously. The Eco-Smart is way better than my old SETS. The Ecosmart does not have the problem where water temp swings between scalding and cold and in fact maintains a rock solid stable temperature. This was a huge surprise as we thought temp swings were just a fact of life with tankless heaters; now we know better! On the inlet side it has a flow sensor so the unit wont turn on unless water is flowing and it has a temp sensor to measure inlet water temp. This is important as the idea is to maintain a constant outlet water temp regardless of the inlet water temp. It does this by calculating the delta between inlet and desired outlet temps and then powers up 1, 2 or 3 of the heating elements to get the desired outlet temp. So winter or summer, the unit should still deliver the same set temp on the outlet side. My old SETS did not have this feature so in the winter it was a guessing game as to where the water temp would stabilize. Becaus eof the temp stability, we followed Ecosmart/DOE recommendation and set the temp dial to 115. Now when taking a shower we need not mix in any cold water (or very little) to get the right water temp. The EcoSmart is well put together as well. The tubing is all shiny copper inside, the flow switch looks durable and th sensors on inlet and outlet are screw in type so they should be replaceable if they ever fail. The thermostats and Triacs look lik ethey are good quality as well and the internals are all well grounded to the common (which in my old SETS I was surprised to find was not the case so it caused a lot of corrosion). The best part is that this modern and well put together unit costs 50% less than what I paid for my old SETS 6 years ago. I am very happy with this unit so far. I will update this review if the unit fails to meet expectations in the future, such as in winter (not much of it here in Florida!).
