To tackle the issue, EcoSmart Eco 11 comes with patented self-modulating technology.  The term “self-modulating” means that the water heater is smart enough to know when to turn itself on. The EcoSmart water heater kicks off at 0.25 GPM water flow in the beginning. The flow sensor regulates the amount of energy it spends, and then, the system turns itself off after it heats the water.  Thus, EcoSmart Eco 11 only heats the water that’s under usage and does not heat any stored amount, and you save hundreds of dollars in your electricity bills. 

– Instant supply of hot water

Consequently, the EcoSmart water heater sets out efficiency of 99.8 percent.  The manufacturer claims that you can save up to 60 percent on energy costs. Well, although it varies with the locality, you can be certain of saving between 50 to 60 percent on the electricity bills.

 Final Verdict 

For its price, the EcoSmart Eco 11 is a high-performance tankless water heater, especially for small and medium spaces. However, you might want to look elsewhere if you’re looking for a central heating system for bigger homes and commercial usage. Nonetheless, in that case, you can use multiple Eco 11 heaters as “point of use” water heaters.  The Ecosmart Eco 11 offers a maximum hot water flow rate of 2 GPM. Although the number isn’t massive, the tankless water heater is well-qualified for studio apartments and small to medium homes. Moreover, it is uncomplicated to use with the digital control panel, and you can save hundreds of bucks with its self-modulating energy-saving system.  Now, if you put everything together, the Eco 11 is a high-performing and low-cost system that can give value for your money along with an instant and endless supply of hot water.
