The constant warmth of the earth is used to heat and air-condition the buildings. During the colder months the “water furnace” takes the 55 +/- degree temperature of the ground and converts it through a forced air system for domestic heating. In the summer the cool 55 degrees of the earth is used to drop the interior temperatures to a comfortable 76.
This system design used horizontal loops in parallel trenches about 6’ deep and 150’ long. The total amount of pipe is 1800’ in use for 3- 3 ton units that heat both buildings.
