Item Description

The smartest hot water solutions for the whole house.

The MAREY ECO series tankless water heaters are the only ones in the market to include a German-designed, patented heating element with a stainless steel water channel. This high quality component is corrosion resistant and reduces hard water build up from chlorine and calcium.

Marey ECO150 units use SMART heater technology. Easy management and simple adjustments on a LCD Panel allows you to program the exact desired water temperature thereby optimizing energy consumption.

Self-modulation of the water temperature assist in the amount of energy used by the heater, thus providing more efficient heating than the old standard type of heating where the heating element is on or off, giving you more consistent temperatures, while saving you money.

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

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.
