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 ECO270 unit by Marey provides 27kW of power, being the perfect solution for multiple points of use in the Southern areas of the US (up to 3 showers simultaneously in such locations). This unit provides 38°F increase at 6.5 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 time. The ECO270 unit by Marey 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 (3) 50 Amp breakers.

Not I nstalled yet

Very satisfied

I just finished installing yesterday. Very happy with purchase process. So far it works great for our home. If I had to have any negative critique it doesn't mount flat against the wall with the mounting bracket so no as stable as I had hoped but don't think it will cause a problem.

I think you should highlight amps needed
