User manual BRYANT GEOTHERMAL BROCHURE

[. . . ] Comfort: These systems provide even temperatures throughout the home year round, with excellent dehumidification during cooling. Environmentally Sound: Geothermal is a clean, green, and renewable technology to reduce your carbon footprint now and for future generations. Reliable: Geothermal units last longer than ordinary air conditioners and heat pumps. Since the units contain few moving parts, they operate for years with little maintenance. [. . . ] Insulated compressor section for quiet operation Filter rack with two-inch MERV 11 filter for indoor air quality Stainless steel drain pan for corrosion resistance Unit Performance Sentinel microprocessor control precisely sequences and monitors component operation for improved performance and serviceability Double spring and grommet compressor isolation for quiet operation Heavy-duty cabinet, epoxy powder coated, with stainless steel front panels for aesthetics and long life Note: Features on other models may vary. 5 6 7 8 9 Frequently Asked Questions Q: How efficient are geothermal heat pump systems?A: Actual efficiencies will depend on a number of factors, but generally speaking a geothermal heat pump can be three to five times more efficient at providing heat than a gas, propane or oil furnace based on the amount of energy consumed to provide a given amount of heat. For cooling, a geothermal system is generally 30-50% more efficient than an air conditioner or heat pump. Q: Why are geothermal heat pumps so efficient?A: Geothermal heat pumps use the ground temperatures as a "source" for heat energy during heating, and use the ground as a heat "sink" during cooling. The earth acts as a giant, free energy battery, providing an endless, renewable source for heating and cooling comfort. Standard heat pumps use outdoor air for heating and cooling. Because the ground temperature is much more moderate and stable than air temperatures, geothermal system operation is much more energy-efficient, especially at extreme outdoor temperatures. Geothermal units are not subject to some of the same forces that cause wear and tear on other types of systems. And earth loops are installed using a special grade of polyethylene pipe with heat-fused fittings designed to last 50 years or more. Q: What kind of underground loop system is best?Homes on larger lots usually have horizontal loops installed. Smaller lots may require a vertical loop. If you have a well water system, that may be an option. Your Bryant dealer is trained to determine which loop design is most appropriate for your home. Regardless of the loop system selected, the operating costs are all about the same. Q: How much space is needed for a closed loop system?A: The smallest closed loop design, the vertical loop, may require a space of only 15x15 feet, or a line of 3x45 feet, located at least 10 feet away from the home, and 10 feet from property lines. Horizontal loops require considerably more space. Q: How is the unit size and loop design determined?A: Bryant dealers use GeoDesigner software to determine the most appropriate sized unit and loop for your home. The software takes many factors into consideration including: the heating and cooling requirements of the home, loop type, depth, soil conditions, earth temperatures, outdoor air temperature extremes, local fuel rates and much more. [. . . ] A: Generally, the existing duct work can be used with a geothermal unit without extensive modification. Variable speed blowers used in many of the Bryant geothermal units can compensate for a less-than-optimum duct system. For the electrical supply, a 200-amp service for the home is recommended. A: A geothermal system can be designed to provide warm water for radiant floor applications. [. . . ]
