Q: How is a geothermal system different from traditional systems?
A: First of all, geothermal systems do not burn fossil fuels to generate heat. These efficient systems transfer the solar heat stored in the earth. The end result is a more environmentally friendly and affordable form of heating and cooling. In many cases, electricity is used only to power the unit’s fan, compressor and pump.
Q: How does a geothermal system work?
A: A geothermal system typically involves an indoor unit and an outdoor, underground earth loop. In the winter, the water-based fluid inside the loop absorbs the stored heat in the earth and carries it indoors. The inside unit then compresses the energy into higher temperatures and distributes it throughout your home or office. In summer, the indoor unit pulls heat from inside the building where it is carried through the earth loop and deposited in the ground.
While outside temperatures fluctuate greatly, the temperature of the earth four to six feet below the surface remains relatively constant year round. The geothermal system extracts the energy from these zones of consistent temperatures.
Q: How much maintenance is required?
A: Almost none. These systems are nearly maintenance-free when installed properly by professionals like Atlantic Loop Master Ltd. The buried ground loop will last through many generations to come. The inside components, the pump, compressor and fan, can be maintained with simple filter changes and periodic checks.
