The Marey ECO240 electric tankless water heater was designed with high-quality parts and components, including a patented heating element and a stainless steel cover. The water instantly heats as it pipes through the heater, delivering instant and endless hot water. It is also called water heater on demand, as the heat exchanger turns on using electricity only when the hot water is running. An external digital control panel allows you to easily adjust the water temperature to be set at your desired output temperature, no matter the water flow. It can heat up to 5 points of use simultaneously.

  • Smart technology avoids the excess temperature waste to any hot water point of use
  • Save up to 60% on electricity bills for water heating
  • Digital panel allows the setup of the output water temperature
  • Only in the market that doesn't get sediments
  • Built with German technology
  • Patent design heating elements that do not accumulate sediments (long life time)
  • Provide endless hot water on demand and only as needed
  • Compact design saves space and is easy to install almost anywhere
  • Unlimited hot water whenever is needed

Rated 3 out of 5 by 4 reviewers.
Rated 1 out of 5 by The top two ratings are fake! I had this lovely little unit installed and it cant even heat up the bathroom bathtub water in our kids bathroom. Ease of installation?? WARNING: you have to run 2 independent 220 volt lines to a dual 2 dual 50 amp breakers. DO not put them both on the same side as it will kick off your main breaker. Customer service is absolutely aweful (puerto rico - so hard to understand) and the repair center is in texas. - all shipping and handling for repairs/returns even under warrantee is at YOUR expense. Don't buy this garbage.... March 10, 2014
Rated 1 out of 5 by NO!!!!!!!!!!! I purchased this Marey unit and have had issue after issue. The unit I purchased came broken. I of course found that out after my plumber charged me to install it. I also of course had to pay the cost of installing new electrical (you need 100 dedicated amps) and various other fittings needed to make the unit work. I then had to remove this unit and re-install my old water heater. I contacted Marey and I had to pay to ship my unit back to them even though it came broken. As I didn’t have much choice I did that. A “new” unit came without any instructions, had clear water marks on the exterior, and had none of the original packaging. After paying my plumber to come out again and spending more money at Home Depot the unit did not work. Jason (who works at Marey) told me the heating coils were not working properly. Marey now wants me to send them my unit and they will again send me another unit. That means I have to pay the plumber two more times. HEED MY ADVICE AND DO NOT BUY THIS UNIT! October 14, 2014
