EcoSmart ECO 27 Tankless Water Heater, Electric, 27-kW - Quantity 1, 17 x 17 x 3.5

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.

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....
