3 Smart Steps for Choosing Tankless Water Heaters

water heater tankless

It is important to figure out your average inlet water temperature, this determines if you can get hot water of desired temp from the hot water heater. Outlet water temp equals inlet water temp plus temp raise(by the hot water heater).


Check the chart to figure out the flow rate suggested for your area and the corresponding outlet water temp to see if it meets your need. For example, if inlet water in your area is 67℉, you are able to get 1.3GPM hot water @ 115℉, if you set temp lower, you are able to get more than 1.3GPM, correspondingly.

Determining specs and electrical infrastructure is important because without the correct infrastructure your unit may not fit onto your breaker panel. we would like to remind you of reading the user manual prior installation and using for the first time.

    I install in studio apartment it’s work perfect l happy

  2. Harley Leestma

    This heater works as advertised, was easy to install with clear instructions. It is used in a garage that gets sporadic use and requires little volume of use. I removed a 50 gal tank that was leaking after 28 years and saved money in cost of equipment. The cost of operation will save more.

  3. Ed B

    Arrived with a screw rattling around inside. Customer Service was quick to respond and gave me permission to break the warranty seal to fix this. Worked okay but then, after 14 months (the warranty is 12 months), it broke. Customer Service was polite but firm: it’s out of warranty. Not surprising, I guess, but disappointing. But then I was contacted again by Customer Service, and was offered a new replacement unit! An unexpected gesture, and it left me feeling realty good about Ecotouch. Problems can arise with anything you buy, so it’s good to see a company stand behind its product. Their great customer service turned a disappointing experience into a positive one. Thanks Elaine!

    I bought this for the one sink we have in our tack room in our barn. I received my first one and it was damaged I contacted the seller within a few days they sent me a new one. I hooked it up and it works great.

  5. Stacy Konieczny

    Love the product, was too many amps for the breaker I had.

  6. Bobbie Ruments

    Our kitchen sink took forever for hot water to arrive from our large tankless hot water heater. So my husband installed a 9KW ECOTOUCH under the sink. We love it. I accidentally bought the smaller one first and ECOTOUCH was very quick to respond to my questions via email (same day). They also were very generous with the return and gave me a small discount on the larger one. Thank you ECOTOUCH!

    Item arrived and I unboxed it to find that the case face was damaged and 3 of the 4 machine screws that are supposed to hold the heating element down were loose and rattling around inside, which left me very unimpressed.The heating element is currently held down by four machine screws that screw into sheet metal brackets welded to the case back. I suspect that, due to the weight of the heating element and maybe some rough handling after manufacture, these machine screws worked them self out (one actually did strip altogether) and then one or more got trapped between the heating element and the case front.In communication with the sellers (who are very good, BTW), I suggested that instead of just relying on the bracket to hold such a heavy component, that each bracket should also have a clip nut. I also asked for a replacement front cover, but accepted a $20 goodwill refund when told that none was available.So I hooked the unit up and it actually works quite well. The thermostat seems to be a bit of a wild card, and I haven’t played around with it enough yet to figure out if it’s over-reading or not, but it appears to be 10 degrees off (higher) than the actual water temperature at the tap. To see if at least some of that temperature loss is between the heater and the tap (which is about 50 feet away – had to put the unit where I currently had 240v for now) I would need to disconnect the hot side again, which I may or may not do.Also, after a bunch of messing around trying to increase the indicated water flow (which, for me, eventually maxed out at 1.4gpm), I am now under the very distinct impression that this unit is incapable of delivering more than 1.5gpm, which is admittedly all the manufacturer claims in at least some of their product info., But, still, they do persist in showing 1.8gpm in all the pictures of the unit and claim a theoretical 1.8gpm in the manual. Certainly I have enough delivery for hand washing but doubt the unit would be acceptable for showering. Please feel free to comment if you have the same unit and are doing better with it (commenting requires a computer – the app does not support this feature).Upate: Unit has failed today with an E2 error code that comes up moment the unit has power applied to it after resetting via the circuit breaker. Have only been able to clear the code and get the unit to resume heating once by resetting the breaker, only to have it shut off with the same error code after less than a minute of operation. Am waiting on contact from the seller but am not optimistic since the unit is out of warranty by 3 months and other reviewers seem to have had customer service issues.

  8. C. J. Vazquez

    Installed today and working great. We struggled to get it to turn on initially, but it worked fine after turning the dial to “eco.”

  9. Michael K.

    This is a fantastic hot water heater. Water is brought up to the temperature set point very quickly and consistently. The digital display is way beyond my expectations, and the style and reliability of this unit are exceptional.
