Marey ECO110 3.0 GPM Electric Tankless Water Heater Open Box (free upgrade to new unit)

Marey ECO110 units use SMART heater technology. It is a technology that self-modulates 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.
