1,067 customers mention "Functionality"849 positive218 negative

Customers like the water heater's performance. They say it performs well even with hard water, and the shower still works fine. The heater is designed for low flow rates (2-3 gallons per minute), so it turns on with very little water flow. It's no problem to run two showers and a load of laundry at the same time, and it's well worth the time and money to install.

working fine so far
04/23/24 installed06/07/24 working well so farCold Water Supply Temperature and Gallons Per Minute (gpm)- currently where i live the incoming cold water temp is 59 deg on 4/23/24 (inlet temp)- the water heater is set to 120 deg hot water out (default outlet temp)- this means the water heater has to raise the incoming water 61 degs (from 59 to 120)- i can run a 2.0 gpm shower and 1.0 gpm faucet and have endless hot water.- this means the water heater is providing a total of 3.0 gpm of hot water when the cold water coming in is 59 deg. it may provide more but i have not tried to run 2 showers yet. i will update this review when i do.- will update this review the next winter when the incoming water temp drops.- you can use a IR Temp Gun pointed at the bottom of a sink next to cold or hot stream to measure the water temperature, over a 5 minute period. a IR temp gun sells for $10 on amazon.- you can also install low flow (water saver) shower heads or flow restrictors in shower heads to enable multiple showers to run at the same time.- the amazon eco-27 page has a picture from the eco-27 brochure showing the cold water temperature for where you live and a chart showing the gpm of hot water out based on your incoming cold water temperature.Power Requirements- the eco-27 requires (3) 40 amp circuits w/ double pole circuit breakers (120 amps) so you need 200 amp electrical service/breaker box.- you must use 8 gauge (awg) copper wires (8-2 w/ ground) from the circuit breakers to the water heater.Flush Valves (Iso-Valves)- the eco-27 uses 3/4" NPT threads so if you install flush valves buy 3/4" NPT flush valves (not IPS).- i purchased these valves on amazon: HQMPC Tankless Water Heater Isolation Valve Kit 3/4" NPT- you can see the Iso-valves in the picture- iso-valves are optional. you may need them you may not. i put them so i have the option of flushing the eco-27.- if your water is hard (lots of minerals, calcium, chalky white stains around faucets) then cleaning the heating elements is a good idea. note that water softeners remove some of the minerals from the water before the water reaches the eco-27.- if you install iso-valves then once a year or so you can use pump vinegar thru the water heater to remove any calcium build up on the heating elements. there are you tube videos on this procedure.- you can also pull the heating elements from the unit and soak them in vinegar (only put the copper section in vinegar) so you do not have to buy/install iso-valves.- you can buy a set of replacement heating elements on amazon as of 4/25/24 they are $69 for a set of 3.Plumber Unions- if you do not install flush valves, which is fine, you may want to consider installing plumber unions to make removing the water very easy. (Note flush valves include plumber unions as part of their design).- with unions you can buy a replacement heater (hopefully you will not need to do this in the first 10 years after the installation of a eco-27) and install it yourself (you might save some big dollars by not needing a plumber come out and rebuild the connections to the water heat.Purging the Water Heater of Air Bubbles- if you turn off you water supply and turn it back on you may introduce air bubbles into the eco-27.- to purge the air bubbles turn off the 3 breakers to the water heater and turn on a few hot water faucets for 5 minutes to ensure there are no air bubbles in the eco-27Installation of Water Heater- i had plumber come by in the morning to install the water heater.- i had an electrician come by in the afternoon to install (3) 40 amp circuits. The old electric tankless heater used (4) 30 amp circuits that used 10 gauge wires so i had to have 8 gauge wire installed from the breaker box to the water heater.Cost of Installation (including tax)423 for the eco-27 (amazon) 64 for the iso valves (amazon)495 for the plumber933 for the electrician---------------------------1915 total installed costDocuments- you can go to ecosmartus.com to download several pdf documents on the water heater.- you can also google eco-27 trouble shooting for a couple of very informative pdfs on trouble shooting.

  • Reviewed in the United States on October 25, 2015
    Style: ECO 27Pattern Name: Water HeaterVerified Purchase
    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.

    Style: ECO 27Pattern Name: Water HeaterVerified Purchase
    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.

    After some conversations with the Ecp Smart company, and a few emails, I order one. The unit was delivered faster than expected. It seems to work only fantastic! Electric hookups took about 90 minutes, and copper work took me about 4 hours with trip to hardware store for parts I didn't have on hand. If you're handy, and are familiar with plumbing and electrical, you can do this no problemo! I installed my first HWT at the age of 10 unsupervised, so this was an easy job. I ordered the 27 instead of the 24 because it was cheaper, and I have the available electrical supply-otherwise the 24 would have done the job. In fact, the 18 would have been fine too.

    This is installed in our cottage which is used only about 5 months out of the year, and mostly on the weekends (Friday-Sunday). I say that to clarify that it is not being used in a house 7 days a week with large hot water requirements. There is one lavatory, one shower and a kitchen tap. We do not have a washing machine at the cottage. There are only 3 of us. Using all 3 taps at the same time, we have plenty of hot water. The unit is set at 120 degrees F. We live in rural Manitoba, and the well water coming out of the ground is about 37 degrees F. COLD! The unit has no problem making enough HOT water.
    The unit is absolutely quiet. I would buy another one in a heartbeat if I needed one. I installed a water softener to treat out hard water which was 390 mg/L. Manufacturer suggests no higher than 200.
    I did consider getting 2 smaller units to place one in the kitchen, and the other in the utility room for the washroom. If it was new construction, I think I would do that instead, rather than using one unit to take care of all locations, quick fix way. But, you do have to wait to get the hot water from the unit to the faucet-just like you do with a HWT. Installing one in the kitchen would have taken care of the wait!
    I will be blowing out he unit in the fall after I do an internal vinegar wash as suggested by the manufacturer.
    Making the 2 connections leak proof was a challenge though, using the Webstone 44043PR IUPS Isolator valves. in the directions, it says not to use teflon tape or pipe dope. I'll guess the reasoning is that they don't want ANY tape or pipe dope debris in the heating elements. I get that. BUT, the fitting to hold with a wrench at the bottom of the unit is really tough to hold onto, and even though the metal cabinet fits fairly snuggle around that fitting, you cannot rely on it to hold the fitting tight while you are super tightening the connections. After 3 failed attempts, I carefully used teflon tape, keeping it about 2 threads away from the open ends of the pipes. One slip of the wrench, and you could probably write the unit off. I would suggest better placement of the fittings at the bottom of the unit, by making them 1/2" longer or beefing up the bottom of the cabinets that the fittings are securely held in place, or considering a shark bit type of fitting.
    Hopefully this unit will last as long as the 28 year old HWT it replaced!

    The idea was to use it to heat Chanelles Granny flat water system, I had to return the eco smart 18water heater. As it was too powerful for our needs. We opted instead for the ecosmart 11, hot water unit which suited our needs more adequately. We received the unit 18 unit in good stead then returned it with the blessing of the agents for the unit. I ordered the 11 unit which has arrived at our FedEx delivery facility and awaiting our pickup. All in all great experience with the company and all personal involved in the adventure thank you all so much for your patience and understanding and support Godbless everyone till next time Arohanui E’Kare’s = much love dear friends.

    Tengo un poco mas de 9 meses usandolo en casa, donde hay 2 baños completos mas el servicio del sink y todo a funcionado sin problemas, cabe mencionar que la distancia maxima del boiler al servicio mas alejado son unos 8 metros, el otro baño a unos 4 metros y el sink mas o menos igual distancia, es raro cuando se usan todos los servicios a la misma vez, asi que no se que tanto baje el rendimiento, probare y les actualizo, lo que me agrada de este boiler de paso, es que si permite regular el agua caliente y fria como si fuera uno de tanque, asi que bastante satisfecho con la compra de este equipo!
    Actualizando hoy 28 Nov, 2023, el boiler sigue funcionando sin problemas, ambos baños pueden usarse a la vez y no hay perdida de agua caliente, sigue funcionando como la primera vez y hasta el día de hoy, ya casi 4 años, no ha fallado ningún componente.

    When a plumber came to connect the unit, they said it is not compliant for installation in Australia because it does not have a watermark. I cannot find a plumber willing to install the unit for this reason. Now stuck with an item I cannot return or on-sell.

    I bought the Ecosmart Eco 27 a month ago to replace a Hubbell 280-3 tankless heater that LITERALLY blew up catastrophically. (You can read more about this below if you are interested).

    I have to say that this unit is head and shoulders above the Hubbell products in a number of ways and if you are in the market for a tankless heater I'd strongly recommend staying away from Hubbell after my experience.

    Overall, this unit does a great job in coastal British Columbia where inlet water temperatures in winter are 50 degrees F or below. Unlike the Hubbell unit, it doesn't struggle to put out 140 degree water with a faucet fully open. The Hubbell never achieved this kind of performance even in the summer months even though it was exactly the same power. Of course, if you open multiple faucets or showers you are likely to see a drop in the temp but most people do not require 140 degree water and should have little problem.

    The controls on the unit are easy to use but you may need to go to the Ecosmart website to find full instructions as the Owner and Maintenance (O&M) Manual they provide doesn't describe things like trouble shooting and the various Error messages you can get. But they are on the website.

    The Eco 27 digital display only lights up when there is a demand for water, and the temperature display can be switched quickly from F to C just by pressing the main rotary temp control knob. Pressing and holding the knob brings up further information including inlet and outlet temp and flow rate. All very easy to access. (Not nearly as easy on the Hubbell)

    I installed this unit myself and as you can see in the photo had to install an additional electrical sub-panel in order to comply with the need for three separate 40 Amp breakers because my main panel didn't have enough space to add extra breakers. Not that difficult if you know what you're doing but it did add about $150 to the cost for the sub-panel, breakers, and cabling. Conveniently, the spacing of the inlet and outlet connections is exactly the same as the Hubbell unit so I only had to do minimal plumbing work. Additionally, the mounting holes are at 16" centres so it can be mounted to standard wall studs.

    Lastly but certainly not the final or least great feature of the Eco 27 heater was the price which is about 1/3rd that of the Hubbell 280-3 it replaced. As I mentioned previously, the Hubbell blew up and the price I was quoted to replace JUST the heating chamber on it's own was DOUBLE the total price of the Eco 27!!

    So, overall, I've been very impressed by this unit.

    For those interested, my Hubbell 280-3 caused me a number of problems over the years including the fact the the original flow meter was made of a hard plastic compound and when I disassembled the unit in order to replace burned-out heating elements, the threads crumbled and rendered the unit unusable due to leakage. I finally replaced the flow meter with a newer brass-bodied unit (that on it's own costs about 1/4 of the total price of the Eco 27) but when I turned the unit back on one of the heating elements burned a hole the size of a pea through the side of the heating chamber in what was, literally, a catastrophic explosion. Very fortunately, I was standing right by the heater when this happened and was able to shut off the power and the water otherwise significant damage from flooding or fire could have resulted.

    What makes this failure most alarming is that, when I contacted Hubbell about it they admitted that they KNEW this could happen but fail to mention it in the O&M manual! I was using the unit 100% in accordance with the manual and yet it still blew up.

    To make matters worse, once this issue came to light Hubbell completely stopped communicating with me, taking absolutely no responsibility for the fact that their unit can fail catastrophically in normal use. Buyer Beware!!
