The convenience of hot water with just the turn of a faucet!
Marey ECO180 220/240-volt electric water heater can provide instant on-demand hot water whenever you need it.
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 a 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 a time.
Please consult the temperature map for suggested points of use according to your geographical area.
This model now has a digital control panel to display the outgoing water temperature. It also has a new and improved heating element. The complete ECO line by Marey is designed with corrosion-resistant heating elements that reduce hard water build-up from chlorine and calcium.
The ETL and NSF rating allows for licensed installers to install in the U.S.A and Canada. 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) X 50 AMP Double Pole Breakers.
What's in the Box? The water heater, an installation guide-manual, mounting hardware, and of course Marey's 5-year all parts warranty.
