The U.S. Environmental Protection Agency (EPA) has released an Environmental Technology Verification (ETV) report confirming 400% efficiency of the EarthLinked® Commercial Water Heating System, developed by Lakeland, FL-based ECR Technologies Inc. The hybrid system combines a high efficiency geothermal heat pump with a standard commercial water heater tank.
The water heating systems, which require little space inside a building, are ideally suited for apartment or condo complexes, motels, colleges and universities, restaurants, health care facilities, food processing operations and a variety of other commercial users.
The EarthLinked water heating system offers the highest efficiency of any powered water heating system.
"The technology has proven itself over twenty-three years of operation,"
Because of high-efficiency thermal exchange with its heat source in the earth, only 100 feet of earth loop per ton of heat pump capacity is needed, and a three-inch- diameter bore hole is optimal. This allows the system to be easily adapted to new construction or retrofit applications.
In June 2006, a newsletter published with DOE support, "In Hot Water,"
"A payback within thirty months is an opportunity for savings that is hard to pass up. Both of our customers who hosted the testing ordered additional units when they saw the results of the monitoring programs,"
