Geothermal Heating and Cooling Services for the Greater Charleston Area
Geothermal heat pumps offer a viable alternative to traditional forced-air HVAC systems. Geothermal optimizes the heat transfer process, which is why the technology is incredibly efficient. Ground source heat pumps can help to significantly reduce your utility bills, but it’s critical to hire a contractor who has the skill and experience to install these complex systems correctly.
How Does a Geothermal Heat Pump Work?
Conventional air-to-air HVAC systems lose efficiency when the temperature outside begins to fluctuate. However, geothermal energy comes from the Earth itself, which maximizes the transfer of heat. The temperature of the earth remains stable throughout the year, so the efficiency of the unit is unsurpassed.
Geothermal heating and cooling equipment incorporates three essential elements responsible for the remarkable efficiencies:
- The Conduit: The conduit serves as the pathway between the condenser and the earth. It’s the mechanism that accommodates the transfer of heat from the ground to your home in the winter and from your home to the earth in the summer.
- The Condenser: The condenser includes the condensing coil, compressor and a number of other components that facilitate the refrigeration cycle.
- Air Distribution Network: A geothermal heat pump can be adapted to work with virtually every existing air distribution method.
Ground source heat pumps are somewhat similar to air-source models, but the critical difference is the addition of a loop-style heat exchanger. Like a traditional cooling and heating system, geothermal provides forced-air heating, air conditioning and radiant heating options.
The distinctive geothermal heat exchanger is actually embedded in the earth through an engineered polyethylene piping system. Open-loop systems must have a permanent water source nearby, which is prohibitive in some applications. Closed-loop designs are more versatile, and they use a sealed antifreeze solution pumped through the underground piping grid.
Benefits of Geothermal Systems
The temperature outdoors can vary by as much as 50 degrees between the lows of winter and the highs of summer. However, the temperature of the earth remains very stable throughout the year. This creates ideal conditions for efficient heat exchange in all seasons. In fact, a ground source system can save up to 40 percent on your monthly power costs when compared to a conventional 14 SEER heat pump. A geothermal unit can also be up to five times as efficient as a furnace rated at 96 AFUE.
Ground source cooling and heating equipment is very attractive for those who are environmentally conscious. Fuel consumption and greenhouse gas emissions are extremely low, and the EPA recognizes geothermal as the most efficient technology available to heat and cool your home.
