Frequently Asked Questions
Q. How does a geothermal sytem work?
A. Throughout the year, outdoor temperatures fluctuate with the changing seasons. However, underground temperatures do not. In fact, about four to six feet below the earth's surface, temperatures remain relatively moderate and constant year-round. A geothermal system, which consists of an indoor unit and a buried earth loop, capitalizes on these constant temperatures.
In winter, fluid circulation through the system's earth loop absorbs stored heat and carries it to the home. The indoor unit compresses the heat to a higher temperature and distributes it throughout the home. In the summer the system reverses, pulling heat from the home , carrying it through the earth loop and depositing it in the cooler earth.
Q. Why is a geothermal system better than ordinary systems?
A. A geothermal system uses the energy from the sun which is stored in the earth to heat and cool homes. Typically, electric power is used only to operate the unit's fan, compressor and pump. Unlike ordinary systems, geothermal systems do not burn fossil fuel to generate heat - they simply transfer heat to and from the earth.
Q. How efficient is a geothermal system?
A. A geothermal system is more than three times as efficient as the most efficient ordinary system. Because geothermal systems do not burn fossil fuel to make heat, they provide three to four units of energy for every one unit used to power the system.
Q. How does geothermal benefit the environment?
A. Because geothermal systems work with nature, not against it, they minimize the threats of acid rain, air pollution and the greenhouse effect. An environmentally friendly fluid is used in the closed loop.
Q. Do geothermal systems require much maintenance?
A. No. Geothermal systems are practically maintenance fee. When installed properly, the buried loop will last for generations. And the other half of the operation - the unit's fan, compressor and heat pump - is housed indoors, protected from harsh weather. Periodic checks and filter changes are the only required maintenance. Annual service agreements are available through Butler Heating and Air.
