working fine so far
5 out of 5 stars
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.

I recently switched to the EcoSmart ECO 18 Electric Tankless Water Heater, 18 KW at 240 Volts, and it has been a game-changer for my monthly expenses. I’m thrilled to report that this upgrade has saved me $80 every month on my energy bills!

The installation was straightforward, and the compact design fit perfectly into my home. What I love most about this water heater is its on-demand heating feature, which means I’m not wasting energy keeping a tank of water hot all day. The temperature control is precise, providing consistent hot water whenever I need it without any fluctuations.

Beyond the cost savings, the EcoSmart ECO 18 has been incredibly reliable. I’ve noticed a significant improvement in the efficiency and performance of my home’s hot water system. Plus, it’s environmentally friendly, which is a big bonus for me.

If you’re looking to reduce your energy bills and enjoy a continuous supply of hot water, I highly recommend the EcoSmart ECO 18 Electric Tankless Water Heater. It’s an investment that pays for itself in no time, and the $80 per month savings have made a substantial difference for my budget!

Reviewed in the United States on April 2, 2014
Style: ECO 18Pattern Name: Water HeaterVerified Purchase
The Good
As for the item itself I would only suggest that the purchaser make sure they have sized the unit correctly for their needs and have taken their area's ground water temp into account. The unit has a sublimely simple design and its shell is both space efficient and cosmetically pleasing. Unlimited hot water is a decadent luxury and Ecosmart makes it affordable to all. My lady is finally able to take her time wash and shave without ever running out of hot water (yikes for my water consumption). Regarding water consumption I'v found that this unit works amazingly well with the "Spa Fire-Hydrant" shower head, Economy and Performance.
The Bad
This pertains to the install process and NOT the unit. -- The plumbing is very straight forward and should be doable by a moderately experienced DIY'er with basic plumbing tools and a little soldering know-how. The electrical work is also not very difficult, BUT requires two Double-Pole 40-Amp Breakers and sufficient sized service to handle the unit (which is actually comparatively large). But if you've got the space or are willing to upgrade your electric service, this item is a must-have.
Final Warning
The large cost for this unit will come from the install by licensed professionals without which you cannot quality for the lifetime Warranty, My advice (if you are not planning to install yourself) would be to get quotes for the install (both plumbing and electrical) and compare those numbers to the cost of the unit if you end up paying more for the install than the unit is worth you might be better off forgoing the warranty because if you do have a problem it would still be cheaper to by a replacement unit.

***One year Update
I've had this unit for a year now and recently blew a heating element, (an issue caused by a plumbing change and NOT the unit itself). I only bring it up because its a bit of a pain to have to order a replacement from Eco-Smart since no other place I found (Even Amazon!**(CAN be purchased on amazon now)) carries this odd element size (9kW 240v Screw-In). So I would suggest having a spare on hand to avoid the shipping time wait if it becomes necessary. Also having seen first-hand what kind of scale and build-up can occur at tragic speeds on the heating elements, do yourself a favor and drop the extra $65 on the recommend 'Aqua-pure' scale inhibitor. Most users can only tell you that it seems to work having nothing to compare it against. I have seen both sides and it makes a world of difference!
Aside from that, I am Extremely happy with this purchase, there is no going back in my household, Even with my girlfriend's new 45-minute long shower ritual (compared to the 25ish she use to get), I have seen a consistent 20-30% electric consumption drop when compared to the two years proceeding it. So my unit will have paid for itself after another year of usage. If your experience is anything like mine you will NOT be disappointed with this unit, so I'd say buy with confidence
***5-year Update
At the 5 year mark, I have been through 2 heating elements (since installed) and always keep 2 on hand to be prepared. I am positive that the unit has paid for itself at least twice and is still working strong. There is absolutely no going back to a standard tanked unit. Until a recent trip out of town in a hotel shower, I'd completely forgot about running out of hot water. The moment this unit breaks I'm replacing it with an identical unit. (A decision made over 2 years ago) every home owner should have one of these units. Save space, save money, and enjoy your unlimited hot water as a bonus for your wonderful investment!
*** 10-year update,
Just blew another heating element (5 in total now after a decade), and they are now available for purchase on amazon! My unit is STILL running strong and my girlfriend has built her own home and installed an Eco27 (As I mentioned, once you've experienced unlimited hot water there's no going back). This device has already well exceeded my expectations and I'm overjoyed to give an amazing review. Love this product and WILL buy again in the home I'm planning to build.

The large cost for this unit will come from the install by licensed professionals without which you cannot quality for the lifetime Warranty, My advice (if you are not planning to install yourself) would be to get quotes for the install (both plumbing and electrical) and compare those numbers to the cost of the unit if you end up paying more for the install than the unit is worth you might be better off forgoing the warranty because if you do have a problem it would still be cheaper to by a replacement unit.

***One year Update
I've had this unit for a year now and recently blew a heating element, (an issue caused by a plumbing change and NOT the unit itself). I only bring it up because its a bit of a pain to have to order a replacement from Eco-Smart since no other place I found (Even Amazon!**(CAN be purchased on amazon now)) carries this odd element size (9kW 240v Screw-In). So I would suggest having a spare on hand to avoid the shipping time wait if it becomes necessary. Also having seen first-hand what kind of scale and build-up can occur at tragic speeds on the heating elements, do yourself a favor and drop the extra $65 on the recommend 'Aqua-pure' scale inhibitor. Most users can only tell you that it seems to work having nothing to compare it against. I have seen both sides and it makes a world of difference!
Aside from that, I am Extremely happy with this purchase, there is no going back in my household, Even with my girlfriend's new 45-minute long shower ritual (compared to the 25ish she use to get), I have seen a consistent 20-30% electric consumption drop when compared to the two years proceeding it. So my unit will have paid for itself after another year of usage. If your experience is anything like mine you will NOT be disappointed with this unit, so I'd say buy with confidence
***5-year Update
At the 5 year mark, I have been through 2 heating elements (since installed) and always keep 2 on hand to be prepared. I am positive that the unit has paid for itself at least twice and is still working strong. There is absolutely no going back to a standard tanked unit. Until a recent trip out of town in a hotel shower, I'd completely forgot about running out of hot water. The moment this unit breaks I'm replacing it with an identical unit. (A decision made over 2 years ago) every home owner should have one of these units. Save space, save money, and enjoy your unlimited hot water as a bonus for your wonderful investment!
*** 10-year update,
Just blew another heating element (5 in total now after a decade), and they are now available for purchase on amazon! My unit is STILL running strong and my girlfriend has built her own home and installed an Eco27 (As I mentioned, once you've experienced unlimited hot water there's no going back). This device has already well exceeded my expectations and I'm overjoyed to give an amazing review. Love this product and WILL buy again in the home I'm planning to build.

5.0 out of 5 stars Great Product Bring on the Savings!
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.

5.0 out of 5 stars A great heater.

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!!

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.

5.0 out of 5 stars Just awesome!

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!

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.
