in response to COLDFLOW GEO HEAT PUMP, posted by ED C

One item to pay close attention to as well as the heat pump, is the ground loop that the heat pump attaches to.

Horizontal pipe MUST be below the frost line in your area in order to keep loop temps near or above freezing in winter. Frozen soil conducts heat poorly.

Next, folks who install MORE pipe than recommended in all climates, hot or cold, are far happier with their systems than those who install the minimum. 10% to 20% more.
