EPA Tests Verify 400% Efficiency in Commercial Water Heating

The U.S. Environmental Protection Agency (EPA) has released an Environmental Technology Verification (ETV) report confirming 400% efficiency of the EarthLinked® Heat Pump Water Heating System.

Lakeland, FL The U.S. Environmental Protection Agency (EPA) has released an Environmental Technology Verification (ETV) report confirming 400% efficiency of the EarthLinked® Heat Pump Water Heating System. The hybrid system combines a high efficiency ground-source heat pump with a standard commercial water heater tank.


The EPA's Greenhouse Gas Technology Center verified that renewable energy from the earth reduced electricity consumption for water heating by 75% at a Florida nursing home. The report also confirmed that the EarthLinked system can avoid the emission of up to 7,000 pounds of carbon and 50 pounds of nitrous oxide per year for each ton (12,000 BTUs) of compressor capacity.

The EarthLinked system developed by Lakeland, FL-based ECR Technologies, offers the highest efficiency of any powered water heating system. The systems have been heating water since 1983, as an optional feature of EarthLinked residential space heating and cooling systems.
They are appropriate for apartment or condo buildings, motels, universities, restaurants, health care facilities, food processing operations and a variety of other commercial users.

"The technology has proven itself over twenty-three years of reliable operation," said Hal Roberts, ECR's CEO. "What's new is the way the geothermal heat pump system is coupled to traditional water heaters to work in tandem to increase efficiency, capacity and reliability to meet high-volume water heating needs."
