    Great Buy!!!
    Review by Ttatemouseon 12/29/2018
    This unit is the best thing I have bought this year. There are many YouTube videos to help install it and the space it takes is nil! If you want to make sure you start the new year with a smart buy then purchase this unit as soon as you can. It pays for itself in the first 3 months. I will be buying more for my rentals. Thank you mary.

    Had problems with the first unit
    Review by georgeostertagon 9/2/2018
    The first unit was purchased from e-bay. After installation it worked for about a week very well and then it started having issues with an e3 code and then an e8 code. the unit had to be reset almost every time before it functioned like it was supposed to. i tried contacting customer support several times and could never get anyone to call me back are answer the phone. I tried to email customer support and could not send an email to the company. The heater is actually an awesome unit when it works. By the way, the original unit is still under warranty. however good luck with that if you cant ever get a hold of anyone.

    Review by Terrion 9/24/2017
    This gas TANK LESS water Heater does a very good job! much quieter than I anticipated. i cannot hear it running. I replaced a 40 gallon tank heater and it is SO nice to not run out of hot water in the middle of a shower. I wish I had done this years ago. Every house should be EQUIPPED with one of these!

    Installed it myself, took a little while to get prepared for new natural gas line & had some plumbing leak issues on the install... today is the first day of full-time use (2/4/17)... runs quietly, seems to be supplying hot water at 120 F easily. We're happy to get it started in our home. Good price with a good reputation. Was shipped very quickly to us (ordered at the local Lowe's).

    Easier than instructions say
    Review by plumber in Californiaon 9/23/2016
    the instructions are redundant and half useless. the hardware is juck in that the washers are to small to match the mounting brackets. the top bracket is the same as the bottom, so the sliding bolt hole is upside down. the instructions say you need a spacer, but spacing has been formed into the mounting brackets. the top mounting holes are blocked by the intake/exhaust stacks. the instructions call for to many shut off valves.
    Start up is simple and straight foward.
    The PERFORMANCE does not match that of a tank on the same 1/2" supply line, except for the ability to provide CONTINUOUS flow. I cannot run the washer and shower at the same time. but I can shower forever. it is pretty to look at, but if you have a 3/4" supply line than step up to a larger unit, one with 3/4" connections.

    Hi! We are glad to hear that you could install the unit easily! We are sorry that you didn’t find all the information in the manual helpful. The mounting brackets and water connections are within the US standards and are easy

    Review by Gregg on 9/18/2015
    Installation of this product was very simple, and easier than lugging out the old tank style heater by far! Once installed we kept getting an error code, I finally called and talked to a very nice lady who walked me through a couple of steps to quickly determine that a wire was disconnected, I took out a couple of screws to open the unit and sure enough there hung the wire in question, not connected. I plugged it into the proper place put the cover back on and had hot water flowing minutes later!

    That was over two months ago and we are very pleased with the performance of this unit, have and will continue to brag about it to friends and family, I wish we had done this years ago.
