About the Manufacturer

Eccotemp Systems, LLC is a manufacturer of energy efficient products located outside of Charleston, in Summerville, SC. Their goal is to educate consumers and trade professionals about energy savings and efficiency primarily in the form of heating water, including benefits, total investments, installation and more. Eccotemp Systems, LLC was conceptualized by Mike Elrod back in 2004. Seeing tankless and heat pump technology was the predominant method of heating water in every other part of the world, he searched out and engineered a solution for the US and Canadian markets. Until Eccotemp, the only tankless units on the market were larger, extremely expensive units. Recognizing that a whole house tankless unit could be engineered, manufactured and delivered to the end consumer for about the same net cost of a standard water heater, Eccotemp was born. Over the past years, Eccotemp has taken a realistic and practical approach to its technology - delivering a state of the art tankless unit at an affordable price point.
