GEOTHERMAL HVAC SYSTEM
Geothermal heating and cooling is very efficient. Yielding 5 units of heating or cooling for each unit of energy required for operation it can reach an efficiency of 500%. Compare this to the most efficient fossil fuel system, natural gas, that requires 0.98 units of energy for each unit unit of heat produced for an efficiency of 98%. Following is an depiction of geothermal system principles and a picture of the indoor unit used in this home. The outdoor unit compises only one well lined with two U-connected lines forming a coolant heat exchange loop.
Producing just slightly more noise than a household refrigerator, the WaterFurnace® Model NDV038 is installed in a utility closet in the Den/Office. This unit features a two stage compressor and variable speed fan in order to operate at the lowest capacity needed to satisfy the thermostat, saving energy costs.
