Keeping a house at a comfortable temperature can be a challenge, especially in extreme weather. Fortunately, every home in the world is just yards away from a reservoir of near-constant mild warmth underground. Using a geothermal heat pump, you can take advantage of this unlimited source to heat and cool your home.

Underground Temperatures

A thick layer of soil provides insulation, so 30 feet underground, the temperature stays roughly constant. The exact temperature depends on the latitude, with the temperature at the equator approaching 75 degrees and the poles closer to 45. Caves and underground water sources tend to stay close to this temperature as well (unless influenced by geothermal activity).

Heat Exchange

The constant temperature underground is a huge asset for regulating your home’s temperature with a geothermal heat pump. This system is essentially like a giant refrigerator coil, which is installed deep in the ground. Inside the coil, which is usually closed to the environment, water is compressed or decompressed to manipulate its temperature. To cool your home, the water will be decompressed, so it becomes colder and absorbs your home’s heat; then underground, the water is compressed again to bleed off extra heat. When heating your home, the system will do the opposite. In either case, having a constant temperature reservoir underground ensures the excess heat or cold will have a place to go.

If you’re looking for efficient and eco-friendly HVAC options, a heat pump is one of the best and most versatile options on the market. Speak with a local heating and cooling company about a geothermal system for your home, so you can take advantage of this natural temperature resource.
