Staying in touch with each other has regularly been important to families and friends around the globe. People have regularly found a way to communicate across barriers and distances. From simple smoke signals, to banners or flags to Morse Code, communication is regularly needed and mankind has constantly created new and better ways to do it. The internet was a huge leap forward in this department. There are so many ways to share information through text, video or pictures. When learning about or researching something new, the internet is an extremely handy tool. The internet was how I was able to find out about geothermal heating and cooling systems. Geothermal HVAC systems take advantage of the consistent temperatures found in the earth to supply energy saving heated or cooled air. The temperature in the ground will stay largely the same despite the temperature in the air changing with the seasons. A geothermal system, which usually is comprised of an indoor control unit and a buried set of pipes, called an earth loop, and a pump employ the steady temperatures underground to supply a low cost energy saving climate control unit. Unlike traditional HVAC units, geothermal systems do not require any oil or gas at all to generate heat. They function by transferring heat to and from the earth. Usually, electrical power is only needed to operate the fan, compressor and pump. Geothermal HVAC units require little upkeep, at least when installed correctly. The piping structure will actually last for generations and the system emits no greenhouse gas whatsoever.
