Marey ECO110 Refurbished Electric Tankless Water Heater 3 GPM 220V



These units are customer returns.   They have been inspected and tested by the  Technical Support at Marey and deemed to be refurbished.

What does this actually mean? 

The customer set-up did not work with this unit and they returned it.  Nothing wrong with the unit.  Sometimes things just don't work out. 

What else does this mean?

You can pick up the "like new " unit for a nice discount on the price. 
These Refurbished units carry the same Marey 5 year warranty. 

The only thing you lose is some of the out of pocket expense.

Item Description

The smartest hot water solutions for a tiny house, apartment or condo.

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 ECO110 by Marey requires 220V and provides 11kW of power, being the perfect solution for 2 points of use in Southern areas (a shower and a sink). This unit provides 28°F increase at 3.0 GPM, allowing you tohave a shower and a sink running simultaneously in hot climates. The ECO110 reaches 56 °F at 1.5GPM for hot water output at one point of use at time. In colder regions, the ECO110 is suitable to provide hot water for a single point of use such as a sink.

Marey´s ECO110 is ETL approved. It performs best in the US Southern regions where the incoming water temperature is above 70°F. This unit must be installed no more than 40 feet from the intended point of use.

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.

Flow switch activation mechanism allows the unit to produce constant temperatures with as little as 0.5GPM / 5PSI.

The Sediment Pre-Filter and Isolation Valve Kit images below are for visual reference only.
Not included with water heater and must be purchased separately.

These items are suggested only and not necessary for this unit to work properly.  

It is recommended that an inexpensive pre-sediment filter be install for your Marey tankless water heater. This will help capture debris or particles that would interfere with the operation and longevity of your unit.             We suggest that you flush your Marey Tankless water heater at least once a year with white vinegar. There are numerous Youtube videos that demonstrate the procedure. By installing an isolation valve kit to your Marey tankless water heater this makes the process much simpler.
