    Review by Johnon 3/26/2019
    The unit came as expected - installation instruction were minimal, but ok. simple attachments for water and gas (replaced an existing tank - of the same size/type, that I had for 14 years. Lets hope this will also last that long. It is working nicely, I like the separate water control valve and the temp valve - lets it fire up with a small water flow.
    Overall, it's fine and for the cost was a good replacement.

    Best Choice Ever
    Review by Annieon 8/26/2018
    My son installed this unit because I was not comfortable working around gas lines but he knows how. He built a frame out of wood attached to the wall studs to hang the unit on because I live in an older mobile home with thin walls. He connected the pipes, inserted the batteries and I turned on the kitchen faucet. Within 20 seconds super hot water came out and it was wonderful. I had been without hot water for just shy of one year due to a broken water valve on my old 32 gal gas water heater. I'm very impressed with how quickly the hot water is made...like instantly and I'm not kidding. We ran two faucets full blast and the unit didn't miss a beat. I still have a small leak in a water pipe not related to the Marey unit because getting dissimilar materials to stay together properly is a challenge. My old plumbing is polybutylene (the grey stuff) so finding fittings is a pain. However, even with a tiny drip in my water pipe the Marey water heater rocks my world. Thank you so much marey. I would highly recommend this product to anyone. I love that it takes no electricity and the batteries were a cinch to install. Only recommendation I have is remember to write down your model number, serial number and other information prior to installing because all this information is located on a plate mounted to the right side of the unit. If you install the unit prior to noting this information you will have to hold a hand mirror between the unit and the wall to view the information, reading the numbers backwards. You will need all this information for your warranty to be activated. I had to use a mirror. Don't make my mistake.

    Review by Sybil Robon 7/21/2018
    We purchased this unit to get an idea of how a tankless water heater would work. Just installed it and so far it isn't working correctly and we call the help line with no avail. We are so frustrated we are about to uninstall and go back to the old tank water HEATER. However, I do not want to do that, this UNIT saves space and I believe that when working correctly will save money. Please someone help before my husband takes the unit out and sends it back.

    Review by Reggieon 3/27/2018
    received the heather in great time (4 days earlier then expected.) installation was average and simple enough for me to do alone. the only problem with this unit is the pressure activated feature; it works great when I use the shower, washing machine, dish washer etc. but simple things like the bathroom and kitchen faucets do not trigger it to come on causing me to have to run multiple things just to get hot water to wash my hands.

    I received the water heater a week after I purchased it, it was relatively easy to install. I would say the only downfall is it does take a little longer for the water to feel hot.

    Review by Kristion 2/4/2018
    A very nice unit. Great price point. We are in zone 5 and it gives us continual hot water. Every contractor that has SEen it wants one. Takes some adjusting to get it to work how you expect, all based on your water flow, pressure INto the unit and at the end appliance. Suggest full flow sheer heads. We are replumbing with 3/4 INCH up from half inch and think it will aid with mixing capability at the shower valve.

    this water heater is met all my expectations! best results when installed as close to point of use as possible. I like the idea of 2 d cell batteries to power the unit. no hard wiring needed and easy to install.

    Water gets as hot as you need it. just set it to your needs. I actually had it too hot to begin with. Installation went into the same place my previous unit was, just needed some adjustments. so far no problems!

    Review by MIKEon 1/29/2017
    unit turns on reliably, but occasionally heats up to close to scalding and then turns off., even though the temp setting is at the lower end of the setting. I'm hoping this corrects itself on its own as the thermostat breaks in. the manual does not address expected battery longevity nor does it describe adequately the process to remove and clean the screen filter or how to flush the unit on an ongoing basis.

    Hi Mike, we are glad to hear that your unit turns on reliably. These units are pressure and flow activated and controlled. At different flow rates you will see different amounts of temperature increase. If the water is coming

    Great traditional tank replacement
    Review by JGon 1/13/2017
    I purchased this unit to replace a traditional 40 gallon tank water heater that burst. The installation was fairly easy once I got the proper couplers to go from 3/4" pipes to the 1/2" connectors on the tankless heater. The heater provides hot water quickly and I have been very satisfied since getting it installed.

    Review by tankon 12/30/2016
    Beautiful product at just the right price. if found if you are having water heat issues with only one of these units than purchase another one and run it in series. id also suggest the plastic tankless water catchers. it makes regular MAINTENANCE on these very quick and easy!! i would also suggest a water cleaner, even if your water is good. if you put clean water in these things and flush them every quarter they will last the lifetime of your house.

    Review by okcflyeron 12/6/2016
    unit was very easy to install once i relocated my water lines to come up to the bottom rather from the top for my old tank heater. level a mark, 4 good anchor screws, and unit was in place. hook up water lines and gas plus convert old 4" vent pipe with 5" i bought from local home depot and i was in business. PROBABLY took me an hour to get it all installed-once i had converted my water lines. installed batteries and turned on water and voila heater came on and produced all the hot water i needed for half my house, kitchen with dishwasher, LAUNDRY and one lav with shower and only took just a bit of time adjusting the flow and heat CONTROLS so that all faucets and machines used the hot water as needed.
    the only issue was a leak from discharge valve (the little stem that sticks down under the unit from the water valve). I CONTACTED MAREY ABOUT THIS AND EVEN THOugh THEY RESPONDED FAIRLY QUICKLY I HAD ALREADY FIGURED THAT OUT. i tightened the bleeder screw up inside there about a third of the way and all was good, so if your unit leaks and you are certain all the waterlines are installed PROPERLY you might check there.
    oh and by the way, i now have freed up a lot of space where my old tank heater was, so this is a bonus. I PLAN ON CONVERTING THE OTHER TANKED HEATER FOR THE REST OF THE HOUSE SOON.

    WE had not been planning on purchasing a new water heater but ours sprung a leak from the bottom and we had to make our decision fast on what we were going to buy. We knew we wanted a tankless heater, we didn't have a huge budget but needed something that would work for our family of 5. We researched carefully and found this unit had great reviews and fit our budget! My husband just finished installing it and is enjoying his first hot shower now. I hope we continue to love this product and see some savings on our future bills!

    Long term cost saver
    Review by Kevinon 9/26/2016
    stylish compact unit. required some gas and water plumbing modifications as well as replacing the existing 3" exhaust system with a larger 5" or 6" diameter (fireplace exhaust size) exhaust system. once installed, the initial burn-in phase takes several cycles to stabilize about 10 cycles. once the unit is stabilized you can fine tune the water temperature by adjusting the gas flow and/or the water flow / pressure adjusting knobs which will take another 5-10 cycles. once the water temperature is comfortable and stable, the unit will no longer require any attention other then periodic check and maintenance. after replacing the old gas water tank with this new marey 16lngdp i've noticed no difference in hot water. i am very happy with this unit. with regular maintenance this unit should outlast replacing the water tank up to 5 times. the bonus is that now i don't pay for gas to keep the tank hot at all times, only when i need to use it. over-all great long term investment.

    we received our unit a couple days ahead of schedule so pleasantly surprised. was able to easily install and tested successfully. we've had tankless before and are used to the learning curve so this unit is performing to expectations. in the past, tankless have saved us considerable heating charges over traditional water heaters and pay for themselves in a couple years.

    I've just installed a Gas 16L NG DP to replace my older (different brand) NG tankless water heater that I’ve used for about 15 years and that I've installed myself to replace a tanked water heater.. The Marey unit offers more GPMs than my older unit, but keep in mind that the water pressure to the unit must at least reach the minimum flow rate to trigger the battery driven pilot/gas burners. Otherwise good unit for the price.
