Geothermal heating and air conditioning systems are starting to gain traction here in Gaithersburg. In addition to energy savings and environmental benefits, geothermal systems are also know for their durability. But what are the actual steps to installing one of these systems? Conceptually, a geothermal system is not much different than a traditional central air conditioning system: it uses a pump to move refrigerant through a series of coils. But while most central AC systems use the outdoor air, a geothermal system uses the energy stored in the ground to provide both heating and cooling. Below we outline the installation steps that allow a geothermal system to do that.
Do you have the space?
With a geothermal system, a series of pipes need to be buried in the ground. When you contact your local geothermal specialist, this will most likely be their first order of business. The size of your house and your heating and cooling needs will determine how much piping will be necessary.
Vertical vs. Horizontal
You have the ground space required for a geothermal system, then you’ll need to start drilling and digging. The series of pipes can be laid out horizontally in the ground or they can be dug deeper into the ground and installed horizontally. The type of soil on your property and your space constrictions will determine which method your contractor uses.
The Heat Pump
At the heart of your geothermal system is a heat pump that will be extracting the heat from the refrigerant being pumped through the coils. The heat pump will blow air over a heat exchanger and then your ducts will carry the air through your home. Heat pumps are normally pretty compact and will most likely be placed in your basement or storage area. Your contractor will be able to recommend which brand or model of heat pump you should choose for your specific application.
A geothermal system works because of the temperature difference between the air in your home and the temperature of the ground. While the temperature in the ground remains relatively constant (around 55° F all year long) the temperature in your home can vary. If you live in an area with extreme cold or hot temperatures, your geothermal system might need some help to heat or cool your home. If this is the case for you, your contractor may recommend the installation of additional heating or cooling equipment to supplement the work of the geothermal loop.
