Geothermal Systems HYDRON MODULE: Geothermal Systems provide a safe and efficient way to heat your home in the winter and cool it in the summer, while saving you money on monthly utility bills.
WHAT IS A GEOTHERMAL SYSTEM
Outdoor air temperatures vary greatly throughout the year while temperatures underground stay fairly constant. The earth absorbs and stores approximately 47% of the sun’s solar energy. As a result, the temperature of the earth four to six feet below grade is fairly moderate and stable. The underground temperature in northern climates is approximately 45° and in southern climates it is in the range of 70° year round. The geothermal system takes advantage of this stored energy by using it to provide the most energy efficient heating and cooling system available.
Rather than generating heat, a geothermal system transfers heat from one place to another. The heat exchanger, commonly referred to as a closed loop system, is buried in the ground and circulates a water solution through a series of pipes. This solution captures the stored solar warmth and delivers it back to the geothermal system located in the house. The geothermal unit then transfers the solar heat throughout the house using standard forced air ductwork or radiant floor heat to deliver comfortable indoor temperatures during the winter.
The same geothermal unit and heat exchanger will reverse this cycle during the cooling season to provide air conditioning. The system removes heat and humidity from the air, transfers and deposits that heat back into the earth through the same loop system.
During the heating cycle, the fluid circulates through the loop extracting heat from the ground. The heat energy is transferred to the geothermal unit. The unit compresses the extracted heat to a high temperature and delivers it to your home through a normal duct system or radiant heat system.
For cooling, the process is simply reversed. Because the earth is much cooler than the air temperatures on a hot day, the geothermal system removes heat from the home and deposits it into the ground. The fluid is cooled by the ground temperatures and returned to the unit for cooling your home.
WHAT ARE THE BENEFITS
- Safe and Secure – no fossil fuel exhaust means a chimney or flue is required. There is no opportunity for explosions or carbon monoxide poisoning, which makes a geothermal system the safest choice for your family.
- Money In Your Pocket – Geothermal systems are recognized by the EPA as the most energy efficient heating and cooling systems available today. Tapping into the free energy naturally stored in the earth produces savings.
- Earth Friendly – Geothermal systems actually have a positive impact on our environment since they burn no fossil fuels and use very little electricity. This enhances our efforts to control pollution, green house emissions, and other issues that impact our everyday environment.
- Noise Free Environment – no noisy outdoor air conditioner is required, so air conditioning no longer has to detract from your outdoor activities. An additional bonus: there is no unsightly outdoor unit to detract from your landscaping.
- Less Maintenance and Service – a single system heats, cools, and produces hot water. Since this unit is located inside the home, it is not exposed to harsh outdoor conditions, which could lead to mechanical issues.
- Comfort, Comfort, Comfort – because of the way geothermal systems cycle, they do a better job of air purification and dehumidification than conventional systems. They also provide more consistent air temperatures throughout the house, eliminating hot and/or cold spots. Additionally, zoning can allow you to maintain a different temperature in different areas of your home.
- Free Hot Water – a geothermal system has the capability of capturing reclaimed heat during the heating and cooling modes thus reducing a typical 4-person households water heating cost by 50% to 60%!
- Longer Life Expectancy – you can expect your geothermal system to provide you with, on average, 20 to 24 years of reliable total comfort and savings as compared to a 13 to 15 year life expectancy of conventional systems.
- Flexibility – there is no job too big or too small for a geothermal system. Our versatile equipment can be installed in existing homes, new construction homes, small shopping centers, and even the largest commercial structures
