Customer Reviews on the Ecosmart Eco 18

I have read reviews for Ecosmart Eco 18 by verified purchasers and summarised them into their pros and cons.

One thing to take note of, be sure to use the Ecosmart sizing guide as a preliminary selection of the possible heater models suitable for your region and family. 

The Pros

Ease of installation and setting up for the Ecosmart Eco 18 was a common advantage mentioned by customers. Other positive feedback include its space-saving design; installation can be done below counter and behind double sinks for accommodations like log cabins. The LED display screen and the temperature knob that allow for easy setting and reading of the temperature were also mentioned. 

This capacity of this electric tankless water heater is an advantage. Despite its small size, it has been mentioned to provide enough hot water consistently for 2 showers going and washing of dishes concurrently for a household of 4 people. 

Customers have reported a decrease in roughly 15-18% in their electrical bills since going installing the Eco 18. This highlights the advantage of using a tankless water heater as a green product.

The Cons

There was feedback stating that wiring the water heater might be difficult for the layman with unclear installation instructions in the manual. The two double pole 40 amp breakers required for installation of this tankless water heater were also an issue for households with limited space in their breaker box to accommodate these breakers.

There was also mixed feedback from customers in terms of product integrity with negative feedback from design flaws like same location of screws for the cover as connecting valves, filter screen in the cold water inlet that prevent the entry of crud is difficult to remove for cleaning. Others include loose riveting and weak enclosure for the internal components. So be sure to carry out a thorough check of your product upon arrival.

The feedback on the Ecosmart customer service was generally mixed. Positives comments range from their helpfulness and responsive to customers queries on topics like installation and troubleshooting. Negatives include no response to both phone and email queries.
