Step 1: Drilling the Wells
The number of wells to be drilled is determined by the heat load of the structure, the nature of the soil on the property and the water table. This is determined on a case by case basis.
Step 2: Grouting the Wells
Grout or other cement product is then pumped into the well hole to secure the loop.
Step 3: Installing the Header for Vertical Ground Loops
The header manifold connects the wells to each other in series and brings the loop into the building,
Step 4: Installing Ductwork, Piping and Geothermal Heat Pumps.
The ductwork for a geothermal installation is identical to an air cooled system. The geothermal heat pump uses heat pump technology but instead of using air to transfer heat, it uses water from the well loops.
Step 5: Flushing and Purging
Before the system can be operated, the loop and well system must be flushed of all impurities. The water in the loop is then treated to prohibit organic growth and chemical scale.
Step 6: Installing the Desuperheater
A desuperheater uses the heat generated in the refrigerant tubing of the Water Source Heat Pump to preheat the hot water of the home, further increasing efficiency.
