Geothermal in basic terms.

In the purest sense, geothermal systems use solar energy. The earth absorbs an amazing 48% of the sun’s energy, leaving a fairly constant underground temperature between 45° and 70° F. Here in Southwest Missouri the typical ground temperature is around 57°.

A water solution flows through pipes buried in the ground (ground loop system) absorbing heat from the earth in the winter and moving it to the geothermal system inside the house. Once there, the heat is condensed and transferred to the air that is circulated throughout the home, providing warmth when needed.

In the summer, the process is reversed, absorbing heat from the air inside the home, similar to how a refrigerator extracts heat from food to make it cool, and transfers that heat into the ground through the same loop system.

Nearly all of the loops installed by Long Refrigeration are vertical ground loops. We use well drilling equipment to drill 200' straight down, insert 2 pipes with a u-bend fitting at the end and back fill the hole.

This is the U-bend fitting at the bottom of the hole. So each hole has 400' of geothermal pipe in it.

The fluid is pumped through the loop field using a fractional horsepower closed loop pump.
