Now we will discuss every feature in detail

Heating Capacity

Ecosmart 11 offers a heating capacity of 2 gallons per minute. It is only feasible for a small household of a maximum of two adults and one kid. The flow rate of 2 gallons per minute means that only one person will be able to take a bath with a shower at one time. If you open any other faucet at that particular time, water pressure will reduce significantly.

Temperature Range

One of the most important things to consider while buying a water heater is the optimum temperature range at which it can operate. The Ecosmart 11 is suitable for a temperature of 67 degrees Fahrenheit and above. The map* available at the official website of Ecosmart will help you in assessing the temperature according to the area.

Temperature Controls

The heater allows you to adjust the temperature controls according to the changes in the weather or your personal preferences. The on/off button needs to be held for 3 seconds to be functional. You can also switch between Celsius and Fahrenheit temperature controls. The conventional rotator handle allows you to adjust the temperature control with a digital display for setting the exact desired temperature.


Installing the unit is not a difficult task; you would need a 60-ampere power supply and 6 gauge copper wire. All the other items required to install the unit comes along the purchase. You can install the unit yourself, but you would end up voiding the lifetime warranty from Ecosmart. Just a pro tip: make sure you do not install the heater at a very faraway place from the major point of use. As the distances increase, the time taken by hot water to reach your faucet increases, and extreme cold weather can also make water less hot.

Technical Details

All the major technical details have already been mentioned at the start of this review. The plumbing connections are 1/2″ compression fitting with the option of 1/2″ NPT adapter included. Ecosmart 11 requires a 125-ampere electric panel for installation with a 60 amp double pole breaker connected to 6 gauge copper wire.


Lifetime warranty gives you peace of mind by increasing the life of the product and giving you more value of money. To avail lifetime warranty, you should get the unit installed from a professional plumber with all the approved accreditation.
