  • 220-Volt ECO 11kW unit is ideal to be installed for 2 simultaneous points of use (a shower and a sink) in US southern regions where the incoming water temperature is above 70° F. In colder regions, this unit is suitable for a sink at 1.3 GPM check the temperature map for more information
  • ETL certified
  • Smart technology: easy management and simple adjustments on a LCD panel allows you to program the exact desired water temperature thereby optimizing electricity consumption
  • German-designed with high quality stainless steel water channel and heating chamber the ECO line by MAREY is the only one in the market with a corrosion resistant patented heating element which reduces hard water build up from chlorine and calcium
  • Requires (1) 60 Amp breaker
  • Maximum GPM achievable is influenced by the kW power of the unit AND the incoming cold water temperature.
  • Endless hot water on demand: activated by water pressure (5 to 85 psi) from the moment the faucet is opened
  • Unit performance is affected if installed above 2000 feet elevation from sea level
  • Regions with incoming water temperature at 55 F or lower consider using our ECO180 or ECO240N models
  • No need for pre-heating: instant tank less water heater on demand heating
  • Tankless water heaters save energy because they use up to 60% less energy than conventional tank water heaters as a result, they are cost effective and environmentally friendly
  • Unit must be installed by a professional plumber or electrician to ensure safety and quality
