The Thermacouple™ Earth Energy System: Is a major innovation In geothermal ground loop construction technology that works with all ground source heat pumps improving energy efficiency. Dramatically reduces the cost of ground loop drilling and trenching operations, making ground source heat pumps more affordable for everyone. Can be used to reduce the consumption of electrical energy required to heat and cool residential, commercial, and government buildings. A single 300 foot system exchanges up to 5 tons of thermal energy with the Earth.
