Ground Source Heat Pumps

A basic GSHP consists of three main components:

• Loop Field: the loop field can consist of either a system of buried plastic tubing which circulates a glycol solution from the ground through a heat pump and back outside in a closed loop, or a series of wells that draw water from the ground, pass it through a heat pump, and then dump the water back into the ground (open loop).
• Heat Pump: the heat pump moves heat from fluid in the loop field and transfers it to refrigerant inside the heat pump. A compressor concentrates the heat before disbursing it throughout the house.
• Distribution System: heat is distributed throughout the home either through forced air via duct work or by means of a radiant, in-floor system.

If you think a GSHP may be in your future please contact Missoula Electric Cooperative for more information on our rebate program as restrictions to apply. In order to receive a rebate, all work must be completed by a certified Performance Tested Comfort Systems (PTCS) installer.
