Geothermal System Installation
The technology behind geothermal heating is very simple, but the installation process can be time intensive and complicated. That’s why it’s so important that you call a qualified expert to help you layout, prepare and start the geothermal system installation process as soon as you’re ready to move forward.
Boehmer Heating & Cooling is the geothermal system expert Pittsburgh area residents trust for installing and maintaining quality geothermal systems. If you have questions about geothermal heating and cooling or you want help choosing your new system, call us today for immediate assistance.
Geothermal heating and cooling systems are very reliable. Because they have few moving parts most of the system is underground or in a building, they are very durable and don’t need a lot of repairs. The heat pump usually lasts 20+ years, and the underground piping usually lasts much longer. While it might seem like the installation processes is more extensive than other heating systems, remember how much longer a geothermal system will last!
What is a Geothermal Heat Pump?
A geothermal heat pump is a system that draws heat directly from the ground and transfers it via condensers into air which is then circulated throughout your home. It’s essentially the same technology used by an air source heat pump, but instead of drawing heat from the air outside your home, a geothermal heat pump uses the natural energy stored in the ground.
To do this, the heat pump uses liquid – usually water and antifreeze coolant – circulated through pipes laid underground in your property. That coolant absorbs heat as it passes through the ground, and then carries the heat to your indoor compressor. The heat is then transferred to air which is circulated through your home via ducts.
In the summer, the same compressor takes warm air from inside your home and transfers it to the water cycling through your geothermal system, in effect cooling your house in the same way as a traditional air conditioning unit.
The Geothermal System Installation Process
Geothermal installation is done in three parts, starting with the addition of heat gathering pipes to your property. These pipes can be laid out in a closed or open loop, though most often they are done in a closed loop.
To install the pipes for a geothermal system, drilling or digging is necessary. Many homes use a simple horizontal installation process which places pipes about four feet beneath the ground over a wider area of your property. However, for especially cold environments, vertical piping is sometimes needed to ensure effective gathering of heat. Vertical drilling, however, costs significantly more money than a horizontal layout, so this is a factor for many new installations.
Once the pipes are installed, a heat pump is chosen. The heat pump you choose depends on the size and heating needs of your home. Larger heat pumps cost more money but they are capable of providing steadier, more reliable heat throughout the winter.
Most heat pumps also provide cooling during the summer. When choosing a heat pump, ask your service provider about the cooling properties of the model you choose. It should be able to effectively draw heat from your home and transfer it into the coolant in your geothermal loop system.
Finally, the ductwork must be installed or directed to your heat pump. If you don’t yet have ductwork installed in your home, this is a relatively large process as ducts must be laid between walls and behind ceilings. Insulation should also be checked to ensure the heating and cooling pumped into your home isn’t leaking out of your home, costing you money. If there are leaks or gaps in your insulation, your heat pump will be forced to work harder to maintain comfortable temperatures in your home.
