1. Understanding what geothermal systems are and how they work
Geothermal systems use the natural heat of the earth to provide heating and cooling for homes and buildings. This renewable energy source is becoming increasingly popular due to its high efficiency and environmental benefits. Essentially, geothermal systems extract heat from the ground during the winter months to keep a building warm, and release heat back into the ground during the summer to keep it cool.
There are two main types of geothermal systems: ground source and water source. Ground source systems use a network of underground pipes filled with a water solution that absorbs heat from the earth, while water source systems rely on the heat transfer of water from a nearby source, such as a pond or lake.
Geothermal systems also use a heat pump to transfer the heat energy to the building. The heat pump consists of a compressor, a heat exchanger, and a fan, all working together to keep the desired temperature. During the winter, the heat pump will extract the heat from the ground or water source and transfer it into the building, while during the summer, it will remove the heat from the building and transfer it back to the ground or water source.
