Professional classic® tankless electric water heaters offer continuous hot water quick and on demand for single point-of-use or multiple applications

The heat electric tank less water heater S-16 model has the capacity of heating 3.5 gpm which is the equivalent to 2 showers (at 1.5 gpm each), and 1 sinks (at 0.50 gpm each) simultaneously, or any combination which equals to 3.5 gpm. The S-16 can handle these applications in the warmer climates of the us which are Florida, Georgia, Louisiana, Texas, Arizona, California, Alabama, and Mississippi. Anything north of these States the S-16 model can be used for point of use, or 1- application at a time. A good rule of thumb is if you live in the southern States mentioned here the S-16 can power a 3 to 4 bedroom 2-1/2 bathroom home, including dishwasher and clothes washer, please keep in mind that tank less water heaters are designed to heat incoming water at a maximum output temperature based on simultaneous use and inlet water temperatures. So if your demand for hot water decreases your output water temperatures will increase, as well as if you live in the colder States this S-16 will heat less volume of water, this will cause the S-16 to be used in point of use applications in the colder climates.

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 ECO110 by Marey 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 to have a shower and a sink running simultaneously in hot climates. The 220V ECO110 reaches 56 °F at 1.5GPM for hot water output at one point of use at time. In colder regions, the 220V ECO110 is suitable to provide hot water for a single point of use such as a sink. Marey´s 220V 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.
