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.

hot water outside for very litte money

Lenee from Phoenix, AZ– Verified Buyer

This is a great item to have especially if you have animals...horses and dogs. Great to give them warm baths in cooler temps. Only issue is with the front vent...it there is any amount of wind the flame goes out....we are looking at a way to block that......overall satified

Love it

Kerry from Nashua, NH– Verified Buyer

I bought this as a dual purpose item. Set up in a camp to use as a shower outside and by installing a tee at the output a method to do dishes with at an inside sink. A great unit that out puts just the right amount of water to do what I want.

The Ecotemp L7

Gene from Houston, TX– Verified Buyer

I have used this water heater at my hunting cabin. Works great, Unfortunately, the shower head was not drained, and I lost it to a freeze. Important to drain all water lines and don't forget to detach the shower head and drain it.

Eccotemp l7

John Dush from Washington state

Unit works great - except I installed one of the batteries wrong. After fixing the user error, the unit fired-up. The first outdoor shower taken was great - we live in the woods, so no privacy issues.
