What customers say
Customers generally praise the EcoSmart ECO 18 for its compact size and energy savings when used in warmer climates or for smaller needs, appreciating the continuous hot water flow. However, satisfaction is highly dependent on proper installation and location. A major concern involves the demanding electrical requirements, as necessary panel upgrades can significantly impact the perceived value. Performance suffers notably in colder regions where the unit struggles to maintain adequate temperature rise for simultaneous use, resulting in lukewarm water complaints. Buyers must carefully evaluate their home's electrical capacity and climate to ensure this efficient heater meets expectations.
