About this item
Product details
This Smart Technology electric tankless water heater is configured as a ""whole home"" model for climates where incoming water temperature is 67F and above. This model is well suited for heating up to 2-Gallon per minute, which is the equivalent of one shower head (with a 1.5 gpm flow) and one sink with a low inlet water temperature of 67F and an output setting of 105F. Digital Temperature Control allows you to set your temperature in increments of 1 Degree. This model can also be used in colder climates as a Point of Use for a sink or other low flow application. All tankless water heaters are sized based on flow rate and temperature rise, and there is a direct relationship between the two. So if used in a cold area requiring a high temperature rise, it will be more limited in the amount of fixtures (gallons per minute) it can heat at one time compared to a warmer climate. When sized properly this water heater will provide endless hot water and only consume the energy needed, giving the user complete control. Prior to purchase and installation please verify this model is the right size for the expected demand and electrical requirements. The ECO 11 requires a minimum 125 amp electrical panel for installation with (1) 60 amp double pole breaker connected to (1) set of #6 awg wire. Plumbing connections are 1/2"" compression fitting with the option of 1/2"" NPT adapter included. For additional assistance please feel free to contact our support center at 877-474-6473.NOTE : 11Kw at 220 is equal to 13kw at 240. .Activation Flow : 0.3 GPM This Smart Technology electric tankless water heater is configured for climates where incoming water temperature is 67 Degree F and above.

Eco-Smart is SMART!
Excellent...and lightning-quick shipment. I prior had a 5500-watt unit for a decade or longer, which was a workhorse. I loved it, and my electrical bills were SO low. My electric bill for winter, December 2024, was $78.34. But, during short Deep South cold spells, my showers were only tepid. This new unit fits the bill for my region. 11,000 watts was just right for my needs. It's a relatively easy install. The manufacturer has spectacular ratings and customer support. Just make sure you have a 6 AWG electrical wire for this unit and a double-pole 60-amp breaker. You cannot put it on the standard 10 AWG (black) wire used for a conventional hot water tank. And make double sure you run lots of water through it BEFORE turning the new heater on. Don't put the new unit on when it is in a "dry" state. Otherwise, I do not honestly understand why people are still reliant on the old-fashioned, clunky, expensive hot water tanks. If you do choose to transition to the electric tankless water heater, be sure to choose a well-known and well-respected brand like EcoSmart.

Does exactly what it says!!😃
Best price at Walmart.com!!! Does exactly what I need for my family of 3 with the occasional overnight guest. We never run out of hot water. Wish it came with everything needed like hoses and that sort of stuff because it was a little inconvenient and confusing for me - someone with absolutely no plumbing or electrical experience! Overall I am very pleased with this product!🥰
