Community verdict
The EcoSmart 13kW Electric Tankless Water Heater functions best as a point-of-use unit for single sinks, small bathrooms, or localized hot water demand. Buyers appreciate its compact size and dependable performance when used within its intended scope. However, reviewers consistently warn that it lacks the heating output for a full home, with many noting severe performance deficits or electrical issues when oversized demands are placed on it.

Great Unit for sinks to showers. This POU heater is perfect for almost any use.
The actual heater is an ecosmart 11, which is 13kW. It cost me $200, but is NOT big enough for the whole house.
not suitable for a house of any kind. if you have a small camper this would probably work.
Installed Ecosmart 27 tankless electric water heater. Now some lights flicker.
