Quick Overview:

The ECO line by Marey utilizes SMART Technology. It is the only one in the market that does not accumulate sediments, as the water never touches the heating element! The 220V ECO180 unit by Marey provides 18kW of power, being the perfect solution for multiple points of use in the southern areas of the US (up to 3 points of use simultaneously in such locations). This unit provides 36°F increase at 4.0 GPM, allowing you to have multiple points of use running simultaneously in hot climates. If you live in colder regions, this unit can reach up to 80°F at 1.5 GPM for hot water output at one point of use at time.


Marey’s ECO180 is ETL approved and recommended for the whole US territory. This unit must be installed no more than 40 feet from the intended point of use and it must be installed by a professional as its electrical requirements demand (2) 50 Amp breakers.


The complete ECO line by Marey is designed with corrosion resistant heating elements which reduce hard water build up from chlorine and calcium.


Please consult temperature map for suggested points-of-use according to geographical area.

    Review by Lillianon 6/14/2019
    I started using these water heaters 7 years ago and I just love them. It easily supplies enough water for an entire 3 bedroom home with two bathrooms. I have trouble getting my children out of the shower now with all the endless hot water. My electric bill dropped over $20 per month once it was installed. I have recently put one in my beach house and do not have to worry about an exploding old fashioned tank water heater. I also have seen the improvements Marey has made over the years and must say it is stellar that a Manufacturer will continue to stand behind their product with a good warranty. Thanks Marey!

    Review by Equality Property Investments, LLCon 5/11/2019
    This item does exactly what Marey promised. It looks great and I am so excited about the space I got back.
    The only thing a potential buyer should know before purchasing this unit is that this heater is not like your standard water heater. Instead of one electrical circuit, it requires two.
    However, the heater is certainly worth it for the space you get back and the never-ending hot water at any given time and eventually a lower utility bill. It took about a week to get it installed but worth the wait.

    Review by JLRon 4/24/2019
    So far the unit meets every need for our household. before installing the unit i called one of the maaey reps to confirm the wiring installation and ground wire awg. all questions were answered to my satisfaction. all connections were easily made. the existing plumbing to our 30 gal water heater mated to the marey eco 180 exactly . no extra fittings or parts were needed. the only item i would like to see is a small led power on light whtn the unit is turned on. I would recommend this unit to everyone. thank you, jlr

    Review by Bigtex78114on 6/28/2018
    So i purchase this unit marey eco180 at my local lowe's store. i need a unit that is small but yet enough to ACCOMMODATE my mother. the unit was easy to install the instruction was great. i did have one issue with the unit that after 1year it stop working. so IMMEDIATELY called my local lowes store and they REFERRED me to the marey customer support. the GENTLEMEN that i spoke with was very helpful and even help me troubleshoot my problem, he explained that if all else fail that he can send me the replacement parts that i need for free and i would just have to pay for shipping. so with all that said and done we were able to fix my problem and i am assured that this company stand behind their product.

    Amazingly powerful
    Review by Daveyon 7/7/2017
    I purchased this unit to replace my 50 gallon tank, since for a single guy 50 galons of water its a lot and i wanted to save some money. Because I live in the north east I wanted to make sure that the unit is powerful to hear water that is cold and fast. I was really amazed, you can easily use 2 points of use and have hot water in both locations. Endless hot showers since hot water never runs out. Week before I got the heater I recorded my daily energy use, on average my daily use was 20 kilowats after installing this unit my daily average is 15 kilowatts. This is truly amazing, since at 21 cents per kilowatt thats over a dollar a day in savings. this is just my estimate and based on my use but I am impressed and love it!

    Seems to work fairly well so far; however, there have been some instances in which the outlet temperature far exceeded the setting and could have caused scalding if not careful. Unit was set at 113 degrees but the outlet temp was reading 139 F.

    5 stars for the marey eco180
    Review by Smokeyon 9/14/2016
    I purchased the eco180 for a summer cabin with a single bathroom. the water is supplied by a very cold well so i chose the 180. the unit is compact, neat in appearance and very easy to install. the instructions were clear and straightforward. the marey unit functions perfectly, very easy to set and read output temperature and provides more than an adequate supply of hot water. i am very pleased with this unit and hope to get many years of service from it. I would happily recommend this unit to anyone needing a similar system. i give the marey eco180 a 5 star rating!

    I bought this tankless water heater for the new home I recently purchased to replace its existing water heater. The unit was easy to install and is very compact. As an added bonus the unit is way more pleasing to look at than a huge tank heater.

    GREAT HEATER BUT THE HOLE FOR THE POWER WIRES IS TOO SMALL. ALSO THE HOLE NEEDS TO BE MOVED ALL THE WAY BACK SO YOU DO NOT HAVE TO BEND THE WIRES TO GER IN THE CONNECTOR. IT WOULD BE A STREIGHT SHOT THEN. WATER CONNECTIONS ARE A BREEZE.
