Features and Specifications of the ECO 27

Here are some of the features and specifications of the EcoSmart ECO 27 water heater:

  • Heats 4 Gallons Per Minute

This heating system is ideal for those who live in areas where the temperature can go as down as 40 degrees Fahrenheit, or lower. This can also mean that you are able to run two showers simultaneously, and it can also handle up to 4 sinks without compromising the actual flow rate, as well as the heating of the water. With this capability, it can provide a steady flow of water to your tub.

  • Self-Modulating Technology

This feature enables the unit to utilize less energy in order to heat the water. As a result, it will save you money out of your electric bill, even as much as 30% compared to a standard water heater.

  • Power and Size

By far, the EcoSmart ECO 27 is the largest, and significantly the most powerful model from this line. Therefore, it is recommended for a huge, yet single family household.

  • Digital Temperature Control

This water heating system also gives you the capability to set the water temperature, just the way you like it. It also has the ability to adjust the temperature in 1-degree increments in order to achieve a personalized output.

  • Internal Jumpers

This heater is equipped with internal jumpers which work in limiting the heat output to a specific temperature of 105 degrees F. This means that if the control of the temperature is not changed, you do not have to worry that the system will heat your water above the limit. This is very valuable especially if you have young children, as well as elderly ones at home.

  • Overall Efficiency

This water heater has been designed to cut on electricity cost. Aside from simply producing hot water depending on your demand, and in sufficient quantities, one of the primary selling points of this model is its energy savings capability. As a matter of fact, this model has a 99.8% rating in efficiency, which is high enough to save on energy costs up to 50%.

EcoSmart ECO 27 vs. EcoSmart ECO 18

The primary difference between the two models under the same brand is with the price. The Eco 27 model comes with a higher price compared to Eco 18. However, this is because it is equipped with more features than the latter. The Eco 18 is also ideal for smaller households, as well as those who do not necessarily have high demands on hot water.

In fact, it can only serve three to four taps simultaneously. If you go over this limitation, you can easily see a slight pressure and flow delays, especially during simultaneous use. One way to address this issue is by installing more than one unit, which may end up with you spending more. The better option, therefore, is by installing the ECO 27 model as it is designed for more powerful use.
