  • Ability to save up to 50% on water heating costs

  • Very stylish and ergonomic design which is highly attractive.
  • Temperature is controlled digitally in 1-degree increments
  • Copper components which are stainless resulting in high durability, greater efficiency, and easy replacement
  • Compact size allowing easy installation and saving on space.

One of the most appealing features of the Ecosmart ECO 27 has to be the self-modulating power control. This activates each of the heating elements as and when the demand increases. So if there is a scenario wherein you are using only one faucet in the bathroom, all three heaters will not be activated. However, if you’re washing a full load of laundry in your washing machine or alternately filling your bathtub, all three heater elements will automatically be activated to bring ensure that the water temperature reaches your setting quickly. This is a great energy saving feature.

The Ecosmart ECO 27 is very well-built, easy to install and reliable. This water heater is a very good value for the price point. Of particular note is that the small size creates more space after you have the water heater installed. Also, replacement parts are readily available at local stores all over the USA. One of the main benefits of buying this is the peace of mind you will get considering the lifetime parts warranty and responsive customer service.

[/thrive_text_block] [thrive_text_block color=”red” headline=” Cons:”]

Users in very cold climates may not be able to achieve the temperature rise claimed by Ecosmart. Computer sensors for the power modulation fail at times; however, Ecosmart has a record of replacing these parts quickly upon being requested. Of particular concern is the fine print which states that the lifetime warranty is valid only upon parts and only if the unit is installed by qualified individuals. To be on the safe side, we would recommend you consider getting the unit installed by a licensed plumber and an electrician.
