Originally on our NOT recommended list due to Chinese components and their main store closing down as well as warranty issues and other problems. It appears Rheem purchased the company EcoSmart Tankless so there have been improvements made with warranty and manufacturing.
EcoSmart Tankless units still are Chinese made and many models have plastic casing which is something we do not like to see in a tankless unit. Reviews have picked up since Rheem took over and the units are now of an acceptable status.
At Tankless Ratings we do not receive any compensation from any tankless company, nor do we have any affiliate or Amazon links as 99% of other sites do. We just rank electric tankless water heaters based on performance, build and value. We have been rating electric tankless for over a decade.
