Ground-source heat pumps will heat, cool entire apartment complex
Throughout the building, Bosch water-to-air heat pumps are tucked away in closets, and pull water from the supply lines. Each apartment has its own heat pump. Two circulators are used per building. A Wilo Stratos handles the circulation of the indoor loop, while a Top S circulates the ground loop. All bore-holes are five-inches in diameter, with one-and-a-quarter-inch pipe.
