HOW IT WORKS
Where do geothermal heat pumps collect energy, and how do they minimize energy bills by 70%?
No matter what climate you live in, the temperature throughout the year varies. For some climates that means blazing summers that cool to frigid winters. What many people don't realize is that the temperature below ground (regardless of climate or season) stays fairly consistent all year. While air temperatures can vary greatly from day to night or winter to summer, the temperature just a few feet below the earth's surface stays an average 55°-70°F year-round.
The ground absorbs 47% of the sun's heat.
and therefore becomes...
Infinite Energy Source for Heating, Air Conditioning and Hot Water.
That's right! The ground is able to maintain temperature consistency because it absorbs 47% of the sun's heat as it hits the Earth's surface. Geothermal systems are able to tap into this free energy with a series of underground pipes called an earth loop. This technology is used to provide your home or office with access to an infinite energy source for heating, air conditioning, and hot water.
As outdoor temps fall, a GHP draws from an underground reservoir of heat, concentrates it, and moves it to your home. Meanwhile, an ordinary heat pump collects heat from frigid winter air, making it least efficient when you need it to be the most. And unlike a furnace, geothermal units don't create heat through combustion. They simply collect and move it.
As outdoor temps rise, a geothermal heat pump collects the unwanted heat in your home and moves it to the cooler earth. Ordinary heat pumps and air conditioners dump that heat outside, but, unfortunately, hot summer air is already saturated with heat and is less willing to accept more, making them less efficient when you need them to be the most.
Setting Up Geothermal at Your Property
A geothermal system uses small-diameter, High-Density Polyethylene (HDPE) pipes buried underground called a "loop." The loop circulates water to move heat energy to and from your home. It's the heart of a geothermal system and its biggest advantage over ordinary heat pumps, air conditioners and fossil fuel furnaces. The type of loop is based on available space, ground composition and installation costs for specific areas.
In Maryland, due to rocky top layer, the best way to install a geothermal heat pump is by using vertical loop.
