Earth Loop System - engineered for efficiency and flexibility

The earth loops are like arteries in a human body. The loops are connected to the heat pump to circulate refrigerant and directly exchange thermal energy with the earth. EarthLinked ground loops have the smallest size and smallest footprint in the market. They have the highest temperature differential with the earth, which means they can use the least amount of earth contact to work effectively. The loops can be installed in three different configurations—horizontal, vertical or diagonal—for maximum design flexibility and cost-effectiveness

The long-lasting earth loops are made of copper, one of the few metals that exist naturally as an element in the earth. A noble metal, copper resists corrosion because of the protective film that forms naturally on its surface. In rare exceptions where pH readings exceed safe levels, we offer the proprietary Cathodic Protection System for the in-ground copper to preclude corrosion in harsh conditions. With installations dating back to 1980, we have never experienced a field failure of a production earth loop due to corrosion.

The earth loops are pre-assembled and pressure-tested for maximum convenience, quality, and easy installation. Depending upon underground conditions, loops using vertical or diagonal configurations are typically installed in less than two days, whereas horizontal loops can be installed in a single day.

A GHP is one of the most efficient residential heating and cooling systems available today, with heating efficiencies 40 to 60% higher than other heating and cooling systems. That directly translates into savings on your utility bills and reduced emissions.

How will I save money with a GHP? EarthLinked systems save money, both in operating costs and maintenance costs. Investments can be recovered in as little as three years. There is a positive cash return, since the monthly energy savings exceed the amortized cost of the system. And don't forget about the Geo System Tax Credit.
