Dear Miss Winters,
In response to your recent query, My staff remains firm in the effort to satisfy your needs.
Space heating and cooling in a geothermal system are provided by a system of water source heat pumps. A water source heat pump (WSHP) is a self-contained, water-cooled, packaged heating and cooling unit, with a reversible refrigerant cycle. Its components are typically enclosed in a common casing, and include a tube-in-tube heat exchanger, a heating/cooling coil, a compressor, a fan, a reversing valve and controls.
With warm regards,
DaveOno
