EcoSmart makes a good tankless water heater. The EcoSmart 18 supplies my 1400 square foot home with plenty of hot water. I also purchased a small EcoSmart 8 which my Westinghouse 9500 watt generator will accommodate in case of a electrical outage. With it I can take hot showers and have hot water for washing dishes in case I need it. I purchased the two tankless water heater’s and the Westinghouse generator from Home Depot. I am very pleased with their service and products.

    This is my first time with an on demand type water heater. It seems to work good so far. It is well made and compact. Wasn't hard to install using a Watts installation kit. The one big problem I had was with leaks at the inlet nipples? Took me many times to get it to stop leaking! Instructions say not to use Teflon tape or pipe dope, it leaked at both connections. I tried tape, they leaked. I tried pipe dope, they leaked. I tried special pipe dope with gasket product (Block), both connections still leaked! I left the dope on and added 4 layers of yellow Teflon tape (thickest tape) and cranked down again, Finally no seepage, YEAH! Still holding. My solution would to have longer nipples on the water heater? I notice when I took connections apart there was only about 3/8" of threads being used in female coupling that attaches to the heaters male connection, with fittings tightened to the fullest??

    Installed this as a alternative hot water system during the Summer months in combination with preheated solar water system. Works perfectly as designed. Installed 5/1/2021. Goal was to eliminate the oil burner operation/dependency during the Summer months. It is installed after the preheated solar water. Very easy to install, very easy operation, but I'm a pro. My tip...make sure to install a way to "descale" it if you have hard water/water softener system. When incoming water temps are "hot" unit uses very little electric. On a good day water temp got to 115 deg, with unit set to 110 deg it uses NO electric.

    Great tankless electric water heater and the best customer service!
    I bought this unit three years ago and it worked great until recently it sprung a leak. So I called customer service and they were amazing! Within an hour I had a new unit on its way via FedEx to my home! Two days later the new unit arrived. The warranty on this is the real deal and that’s what’s very important with these type of wireless tanks. I know they do they do not last as long as your standard hot water tank but that’s the trade-off. You get fast unlimited hot water but it won’t last 20 years. But with this warranty and this great customer service this is the perfect product! Very happy with this purchase and dealing with this company.

      Leaks at the element tank.
      Careful, mine started leaking and instead of repairing it they say "Oh , you have to disassemble the unit, pull out the elements and soak them in vinegar and replace the o-rings - annually"! And by the way, the manual that comes with it fails to mention that. So go pay a plumber to do all this for you.. They do not stand behind their product.

        This is my second one in less than two years. Word to the wise: BE SURE TO SEND THE REGISTRATION CARD IN, otherwise there is NO warranty of any kind. Hoping the second one lasts longer.

          Very happy with product! I had family over for two weeks, and ran two showers with people using bathroom facets without any change to temperature. Easy to install, and would highly recommend!

          Burst after 10 months
          This was my sixth unit and it too failed within one year of installation. We’ve gone through six of them due to failures and having to keep with the same model for replacements. Previous replacements had issues with the heating elements or temp sensors going out but this time the heating element separated from its threaded cap. We woke up to find 2 inches of water in our bathroom and closet, along with drywall damage because the heater was located in the attic. After thousands of dollars worth of damage, it wasn’t worth it to exchange this unit for another one of its kind. I instead purchased a Rheem heater, and to my dismay it is identical internally, down to the same exact part numbers. Eco-smart warranty is nonexistent, so don’t plan on the manufacture helping you out. If you have already purchased this unit, it is in your best interest to establish some sort of extended warranty or home appliance warranty, this unit will fail it’s just a matter of when. I would also recommend installing an aluminum drain pan designed for tankless heaters, you can order from Home Depot for about $60.
