The Marey ECO180 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.

  • 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
