The ECO 27 tankless water heater provides you with many features that make it worth the buy. You get your money’s worth when it comes to the longevity and usability of the ECO 27.​

  • Self-Modulating Technology. This allows the unit to use less energy to heat the water, saving you money on your monthly electric bill. For example, the ECO 27 can cut your electric bill by as much as 30% if you switch from your traditional water heater.
  • Heats 3 GPM. This makes it ideal for the Northern United States with water temperatures below 40°F. This means you can run two showers and up to four sinks simultaneously while not compromising the flow rate or the heat of your water. It can even provide a continuous supply of hot water to your Jacuzzi tub or your roman style tub.
  • Digital Temperature Control. Allowing you to set your temperature how you like, it can adjust in increments of 1 degree for the most customized output.
  • Size & Power. This is the largest and most powerful model with self-modulating technology from Ecosmart’s line of tankless water heaters, so it is ideal for a large single-family home.

Advantages of the EcoSmart ECO 27

  • Powerful. The Eco 27 is perfect for the Northern States of the United States and Canada, with colder temperatures as low as 37 °F. The unit can heat water quickly and efficiently thanks to the self-modulating technology. This technology allows it to provide enough hot water for a large single-family while not increasing your energy bill but, on the contrary, decreasing it.
  • Safe. The heater has internal jumpers that limit the heat output to a temperature of 105 degrees Fahrenheit, so your water heater will never heat your water beyond that if not changed. This is great if you have the elderly and young children at home.
  • Easy to Clean & Maintain. Once your unit is professionally installed, you get a warranty, and cleaning and maintenance can be done quickly and easily. All you need is a Philips screwdriver, and you are good to perform any routine cleaning that needs to be done.
