Quick Overview:

The ECO line by Marey is designed using 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 ECO270 unit by Marey provides 27kW of power, being the perfect solution for multiple points of use in the Southern areas of the US (up to 3 showers simultaneously in such locations). This unit provides 38°F increase at 6.5 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.


The ECO270 unit by Marey 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 (3) 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 Nomadon 8/9/2017
    I think it will be what we want.
    The only con so far is the water pressure through the unit is lower than we had with the tank and you have variable temp water at other locations.

    Review by Enviro-phobeon 1/9/2017
    This ECO 270 purchase/review is because of an upgrade from the ECO 240, I returned under warranty. The ECO 240 is my second tank-less water heater. My first was a Home Depot 2002 purchase replacing a flooded mobile home from a mini hot water heater failure. That first tank-less survived for 9 years of single resident use. I plumbed and wired in the unit in, and in error I neglected to add flushing valves. However; the unit lasted for nine years. It was close to the same size as the Marey ECO 240 and I must recall the water source-type were fundamentally different.

    The Marey ECO 240 was about the same size as the mobile home unit. The mobile home unit did not demand I professionally install the unit to meet the warranty. But, I was in a rental, under a great rent agreement and the appliance repairs/replacements were completed by me to remain low in profile to keep rent from increasing. (It worked, as I lived there for 12 years with no rent increase.) On the contrary, the Marey ECO 240 home installation required a professionally licensed plumber and electrician perform the installation. Well, the plumber informed me to consider a flushing valve set. But, he plumbed the valves upside down! I was unaware of flushing as needed. I had many roommates placing a lot of demand for hot water. The water was of a different consistency than in the mobile home installation; basically locally stored rain water. Eventually, the Marey plugged and failed to perform after 2 & 1/2 years demand. I failed to flush the unit regularly! My plumbing in this home was 1945 galvanized and problematic. All faucets, from valves to aerators have clogged in that 2 & ½ years. (in fact, I have $1000 in Pex to re-plumb this residence this coming summer.) Not counting the multiple piping types from failure to freeze.

    A long story short, I like this unit. The Marey folks stood by me. They sent me a reconditioned ECO 270 as a purchase upgrade. (I purchased a second unit.) I sent back an ECO 240 for warranty repair. I own this home and will have two tankless units. One may set in my storage if needed...cheap insurance to my belief. I might plumb in a second if I continue to expand the residence. As a user, I believe I do not need two units or to distrust this tankless, but to become familiar with the demands of one’s roommates, the plumbing condition, and the flush requirements comparative with the actual municipal water makeup. It would be good advice. If one thinks the tank water heater versus this tankless fail to compare in consideration of my above example, you must take the time to research tank water heaters and the unique relation/expense associated with their consumption.

    I have purchased a swimming pool rated submersible pump, due the acidity of chlorine, comparative to vinegar the medium used to flush the Marey, a handful of hoses and fittings for pushing vinegar through the Marey annually, three gallons of vinegar (that I might filter, place on the shelf for reuse yearly, a stainless steel 'Y' with an easily removable filter for watching the plumbing particles from the old galvanized pipes. I added a pressure gauge at the head of the ‘Y’ screw off filter to watch the unit at demand pull from the water source.

    All said, this repair, due my ignorance and professional plumbing error has cost under $200. The Marey will never rust out. The web research suggests this unit will perform longer than a couple of traditional hot water heaters. Tankless water heaters are luxurious due forever hot water delivery and they save energy if used equally to the old tanked water heater.

    I relay this story as a semi experienced user. I am very much sold on the Marey. They have supported me well. I was not blamed due the unique circumstance surrounding my ignorant sighting. I was not blamed for failing to flush properly. I paid $46 to return the ECO 240 and they sent me an ECO 270 rejuvenated/reconditioned unit when I purchased an ECO 240 rejuvenated/reconditioned unit, at no extra charge. They paid that shipping for the ECO 270. I will find out if they repair the ECO 240 as a warranty or charge me for some or the entire repair, for the original ECO 240.
    I reviewed this purchase with 5 stars, inclusive of my consideration if “I would recommend it to a friend.” I recommend the concept of the unit, sparingly, as I dislike leading others where they seldom care to go anyway. I fail to suggest the Marey to friends as I feel they should shop for the unit that makes them happy. I shopped diligently for a tankless and decided upon Marey for obvious reasons meeting my evaluations in consideration the market availabilities.
    I would purchase the Marey unit again!
    Great customer support team!
    Sincerely,

    We own Residential rental properties and have a small apartment complex with small apartments. huge water heaters take up too much room so we were excited to try a tankless one. it has been installed now for almost one month and seems to be working fine! if this one does well we will be installing in all our units!

    Review by PMMARIONon 11/30/2016
    iT TOOK ME A BIT OF TIME TO UNDERSTAND THAT WITH THE TANKLESS WATER HEATER YOU DO NOT USE THE COLD WATER TO ADJUST THE HEAT. NOTHING IN THE INSTRUCTIONS TELL YOU THAT YOU DO NOT TURN ON THE COLD WATER WHEN TAKING A SHOWER. IT IS A BIT OF A PAIN IN THE TUCKUS TO HAVE TO GO AND RESET THE TEMPERATURE WHEN I WANT TO WASH A LOAD OF CLOTHES OR WASH THE DISHES. THERE SHOULD BE A REMOTE TO CHANGE THE WATER TEMP.
