However, when no hot water is being used, the power consumption is 0 (or a minuscule amount to run an LED light or something). The total power consumption over the course of several days or longer should be much lower than a tank heater but the short term power usage while the heater is making hot water will be much higher than a tank heater. It’s just that the unit sits idle most of the time while a tank heater will use power fairly frequently even when no hot water is needed as the water in the tank cools off over time and needs to be re-heater fairly constantly **Q: Can this unit supply a 3,700 sq foot home with 3 1/2 baths?** A: I live in the Midwest and it's been great for my 500sqft home 1 fixture at a time, WITH THE EXCEPTION of my bathtub's faucet in the winter. Once temperatures go below 30f - 40f outside, it can't keep up with that tub faucet which I imagine is pumping out 4GPM and trying to get it up to the 110f - 130f range. It's winter now and I just tried out more combinations: bathroom lav (sink) + kitchen sink work well together at full blast -- napkin numbers put this at 1.25 + 1.5 = 2.75 GPM bathroom lav + shower head work well together at full blast -- 3.75 GPM kitchen sink + shower head start struggling to keep up with demands - 4 GPM (same as bathtub) I'd say it works very well for what it advertises, and besides winter hot baths it's been amazing. I'll likely try to install a flow limiter on the bathtub to get it down to the 3GPM range and I bet that will get me hot winter baths again, albeit a little slower but I'm okay with that. If I remember in the Spring once temps go back up past 40+ degrees I'll try this again! **Q: I have a double pole 30 amp breaker would be possible to just change the breaker as I have a two story house and wiring is in the areas between floors** A: If you have three 40 amp breakers, are you running one wire from each breaker to the unit or two from each breaker? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Has worked like a charm - plenty of water and saved a lot of money *by on Reviewed in the United States October 27, 2012* 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. ### ⭐⭐⭐⭐⭐ these devices work well but here's what you need to know about costs and electrical and drawbacks *by on Reviewed in the United States October 17, 2020* Trying to get rid of gas heated anything in the house to protect the family - I bought this - problem with it is only one thing..... for a LARGE 3 full bathroom house if you used the furthest away bathtub from the unit (downstairs garage) you could not put it on highest setting to get water out of the bathtub - you had to put it on like medium flow of water coming out to get it to super scalding hot - it could not keep up - that being said - showers were no problem - scalding hot - also cut down on my bills - no more gas bill at all plus increase in the electric bill b/c of this unit was about 1/2 of what gas was b/c only ever turns on when water flows period... it was fine to use in multiple bathrooms and kitchen at same time also FYI.... so these were all my worries thinking I was totally screwing up buying one of these devices - but it works!!! one last note::: it cost me $800 to have an electrician put in 4 of the 40AMP connectors necessary to run this device which cost in the end more than double the cost of this device - it will NOTTTT work without a 40AMP and it's very unlikely you have 4 extra 40 AMP connectors on your electric grid in house and if you do they are used by something else guaranteed ! this is something they did not mention!! even though it's on the box it's umm wow... ugly cost - also the cost to BUY the 40 AMPs switches were ummm $60ish or where they $100 ish I forget ... so over $1000 total cost on electrician plus switches! sheesh... but I'm saving about $50 per month by switching to this so in 2 yrs it's paid for anyway but still - sheesh -I will give also another word of advice - I looked thru 100 of these devices - OMG so much work - let me tell you that had I spent that amount of time searching instead of a person who installed 100s of these before (a full plumber/electrician company) I would have probably saved crazy money b/c I don't thing I would have been spending that $1000 to $1200 for an install - I think they would have handled the whole thing for like $700 ish (install for plumbing for this device PLUS upgrade of electrical PLUS 4 switches cost etc) ... OOPS... I did not find this out until RIGHT AFTER the electrician was done - my friend had called me the day of or day after I had it all electrically upgraded to tell me they had found about 3 others that do this all the time in addition to working all sorts of other construction jobs - they did say however these devices are all quite GOOD if you do not go cheap like $187 one - notice I got the 2nd to most powerful one in existence the 27 version with 4 of the 40amp connectors and so on... they said they just dont have trouble with these devices but they do require maintenance like de-scalling the calcium scales off every few yrs - I never need that though b/c I have a water enhancement unit that forbids scaling for life - hehe.... ### ⭐⭐⭐⭐⭐ Great Product Bring on the Savings! *by on Reviewed in the United States October 25, 2015* Reason(s) for purchase: 1. Save $ on energy cost 2. Our tank water heater wasn't getting the water hot enough (could have been goingout 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 thisproduct 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 thisparticular model because I would much rather have too much than not enough. It's all about the incoming temperature and living in Hawaiithis product should do the job for us (4bd 3bth).I will update on actual savings in $ but keep in mind that each state charges differentamounts per kWh (Hawaii charges x3 of the national avg. so savings may appear more drastic) and families use different amounts ofhot water, but at least it will give you an idea.Pros: -Unlimited hot water -Supposed to save $ on energy-Frees up valuable space -Looks ModernCons: -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 waterInstall: Install "can" be fairly simple for the average DIYer if you can follow instructions and a few safety guidelines. The hardestpart is running the wiring to the electrical panel. Everything else is pretty easy. If your breaker box is in the same room as yourplumbing the install should be cake. Just make sure that your work is done to code. Wife and I installed it together (she helped run theelectrical wiring to the breaker box). Ours was across the room in the hallway. It actually took us two days working a couple of hoursto run our electrical (a different story for another day). After running the electrical it probably took me 30 minutes to an hour tofinish 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 getshotter 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 gethot 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 acomplaint..... 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 buya tankless water heater. Just do your research and makes sure that it will fit your needs. My wife regretted this purchase after havingto 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 sheis 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.
