Summary

Geothermal heat pump (GHP) ground loops can overheat and become ineffective in providing high efficiency cooling and extended service life. Some experts contend this will almost always occur for buildings with imbalances in cooling and heating loads and that the assistance of a fluid cooler or auxiliary heat is necessary. Apparently, this is not universally true, since engineers and contractors have been able to avoid loop overheating in south central Texas and operate systems with outstanding results as indicated by average ENERGY STAR ratings of 97 on the GHP systems.
