Installation of the heat exchanger to the soil is not without danger. Disrupting or heating existing soil layers can have serious consequences for the groundwater. A result can be pollution of the water.
A huge disadvantage of existing systems is that heat exchangers must be placed deep into the ground to let the pump system work. A perhaps bigger danger of the existing systems is that these systems are filled with several liters of toxic glycol, a liquid that can pollute millions of gallons groundwater in case of leakage. With Geothex all these problems and dangers belong to the past. Geothex can work without the addition of glycol and the heat exchanger works already at a dept of 10 to 25 meters. The yield is higher than the existing systems. Because the Geothex is a safe system, the groundwater stays free from contaminants.
