Stable Temperature from the Ground
The Vertical Ground Loop Heat Pump System utilizes the constant temperature of underground soil. It extracts heat from the soil in winter for heating and rejects heat into the soil in summer for cooling. One system meets both seasonal requirements. The soil temperature remains stable at 15℃ to 18℃ throughout the year, ensuring highly stable operation. The equipment is a reliable year-round energy solution.
High Energy Efficiency
The heating COP ranges from 4.0 to 5.0. The cooling EER ranges from 3.5 to 4.5. The system uses vertical U-shaped ground loops, available in single U or double U configurations. The drilling depth ranges from 80 to 150 meters, and the drilling spacing is 4 to 6 meters. The pipe material is HDPE PE100, ensuring long service life. The system design life exceeds 50 years. The Vertical Ground Loop Heat Pump System delivers long-term stable and efficient performance.
Key Advantages and Unaffected by Weather
The main advantage of a ground source heat pump is that it is not affected by outdoor weather conditions. Unlike air-source heat pumps, which lose efficiency in cold winter conditions, ground source systems maintain stable performance because underground temperatures remain constant year-round.
We have been in business since 1996 and have extensive experience in ground source heat pump systems. We are an ABB-authorized system integrator, ensuring reliable control system performance and stability.
If your project site has sufficient underground space, vertical ground loops can be considered. We provide design support for drilling depth and loop quantity to ensure optimal heating performance while controlling investment costs. The Vertical Ground Loop Heat Pump System is a smart long-term energy investment.
