How Geothermal Heat Pumps Work
Basically, geothermal heat pumps take heat from the ground below and around your home and transfers that heat into the air of your home. This is possible because of the loop of pipes that extends into the soil around your home as part of your geothermal heat pump. The liquid, usually a mix of anti–freeze and water, flows through this pipe loop and is able to absorb heat from the ground. It then returns it to the compressor unit inside your home where that heat can then be transferred to the air.
That heated air is then distributed throughout your house by an air handler or blower as the liquid returns to the ground to begin the cycle over again. Unlike furnace–based forced air system, geothermal heat pumps do not provide strong blasts of hot air periodically. Instead, they produce a continuous stream of warmer air that can keep your house at a comfortable and consistent temperature.
In the summer, however, the process is reversed and a geothermal heat pump can take the heat from the air of your house and transfer it back to the ground. This means that a geothermal heat pump is really a year round solution for keeping your home at a comfortable temperature.
Geothermal Heat Pump Energy Savings
Because geothermal heat pumps do not actually produce heat, they require very little energy to operate. That can translate into substantial savings over time as you will wind up using much less energy to keep your home comfortable year–round. While it is true that installation of a geothermal heat pump is more expensive than the installation of a traditional furnace–based system would be, you will quickly make up the difference in monthly energy bill savings.
Geothermal Heat Pump Installation Options
There are actually several different ways that your geothermal heat pump can be configured. Probably the most common installations are horizontal ones. To complete this type of installation, a trench is dug in your property near your house. This trench is usually about 4 feet deep and anywhere from 100 to 400 feet long depending on your household cooling load.
The loop of pipe is then laid in this trench and connected back to your home and the compressor unit. Alternately, you can opt for a vertical installation. This is generally only used in areas that experience extreme cold for prolonged periods of time or when you do not have enough space around your house to accommodate a trench.
A vertical installation usually costs more than a horizontal one because although the loop of pipe can generally be shorter, the process of drilling the hole is considerably more costly. However, sometimes a vertical installation is your best option. One of our professionals will be able to assess your particular situation and make a recommendation.
