EcoSmart ECO 18 Electric Tankless Water Heater

The EcoSmart ECO 18 electric tankless water heater is one of the most well-designed medium-sized tankless heaters on the market. Both professional and consumer reviews have been positive. In addition, this model on demand is fully equipped with all the technology and features required to provide reliable performance for many years.

Natural gas water heaters are best for those who live in cold areas. However, ECO 18 models are suitable for those who live in moderately warm environments (think 62°F). This unit heats water at an average rate of 2.5 gallons per minute if the water temperature is between 60 and 65 degrees. The output temperature is 105 degrees.

The ECO 18 is not a traditional water heater. It does not store hot water. Instead, the temperature control knob is located at the front of the unit and allows you to adjust the water temperature one degree at a given time.

The Key Features

  • Smart design can help homeowners save up to 50% on their monthly electricity bills.
  • The self-modulating technology allows the unit to adjust its energy consumption based on how hot it is.
  • Digital controls with one-degree increments allow for complete control of water temperature.
  • Copper and stainless steel components provide durability and efficiency.

Review of Product

The ECO 18 is intended to work in “whole-home” areas with an incoming temperature of 62 degrees Fahrenheit. The unit will work with any temperature water, but colder water will have a greater impact on the hot water output than gallons per hour. The ideal temperature for the ECO 18 is 62 degrees. It can produce 2.5 gallons per minute of hot water with an average output temp of 105 degrees. This model’s most popular feature is the digital temperature control. It allows the user to adjust the temperature by increments of one degree.

The EcoSmart 18 is not intended for outdoor installation. It should be installed in an enclosed area protected from the elements, rain and other adverse weather conditions. EcoSmart encourages customers to have it installed by a professional plumber. EcoSmart’s lifetime warranty will be voided if a homeowner installs it himself. The water heater does NOT require venting. The water heater is “whole-home” and can be placed anywhere in the home to provide the entire residence.

The ECO18 models have been well-reviewed by customers. They are very popular due to their low prices and precise temperature controls. EcoSmart is the preferred choice for homeowners considering tankless water heaters. However, buyers must be realistic about what they expect from this model. The water heater’s self-modulating design will be about a 30-second delay between opening the faucet and water flowing out. The ECO 18 will save you more energy over time than a traditional water heater with a tank. However, the initial cost is higher than a conventional water heater.
