ECO 11 is an energy efficient water heater designed specifically for home use. It’s a great water heater for small to medium-sized families.

The ECO electric water heater is a compact and tankless hot water generator that promises to save you 60% on heating costs. This advanced self-modulating water heater generates a steady stream of hot water in seconds. Perfect as a “whole home” water heater, the ECO 11 can heat 2 gallons of water in 60 seconds. This unit is ideal for warm and cold climates alike and it only consumes electricity when needed. This means you are given full control over your water heater while reducing energy at the same time!

For installation, this product requires about 125-amp electrical panel for installation and 1 60-amp double pole breaker connected to a set of #6 AWG wire. Unless you’re a handyman, setting this up will require professional help. The ECO 11 is designed specifically for home use and it’s a great water heater for small to medium-sized families. One of the things that we loved about this unit is the lifetime warranty. EcoSmart is so confident that you’ll love the ECO 11 that it’s offering a lifetime service guarantee to all customers, something that we wish all brands offer.

Now for the downside, most of the complaints that the ECO 11 received are for being faulty. We did not have such issued with our test unit but this is something worth noting before making a purchase.
