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.


  • The 220V ECO 27kW requires (3) 50 Amp breakers.
  • This unit must be installed by a professional plumber or electrician to ensure safety and quality.
  • 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.
  • SMART Technology:  easy management and simple adjustments on a LCD panel allows you to program the exact desired water temperature thereby optimizing electricity consumption.
  • Recommended for 3 simultaneous showers (1.5 GPM each) in hot climates (US Southern regions). In colder regions, this unit is suitable for a shower at 2. GPM and a sink at 1.0GPM. Check the temperature map for more information.
  • Marey’s ECO line can maintain 98% efficiency level throughout a lifetime.
  • No need for pre-heating: instant hot water on demand.
  • Activated by water pressure (5 to 85 PSI) from the moment the faucet is opened
  • ETL approved.
  • 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.

Marey products come with a 5 year manufacturer warranty.

Customer Reviews

Based on 4 reviews
item great customer service very very poor

i had item for 8 months started blowing breakers. called customer service took us calling 6 times and 2 weeks later get a response. did every thing they asked to get fixed and still kept getting run around till year was up then wanted me to pay to ship to them and pay to fix product warranty crap then they wanted proof of where item was purchased after all info was giving when it was registered. needless to say i gave up and bought a ream.

Customer Service

Factory Pure's customer service was the best. I had a question...I asked the company who makes the Marey hot water heaters. They failed to responds after several attempts from myself and my installer. Factory pure was able to arrange a call and the solution was found. Thanks Factory Pure.
