About Geothermal
Geothermal Heating and Cooling systems are an efficient, Green way to condition your home. Geothermal or Ground-source Heat Pumps (GSHP) are nothing new, the technology has been around for 40 years but has gained steam in the last 15 years with advancements in the technology. Geothermal systems are quite simple… in a nut shell they heat and cool the home using stored solar energy in the ground.
Here is how it Works…
During the heating season heat energy (average 45-50 degrees) is transported into the home via water or and antifreeze solution and into the heat pump. The heat is then compressed via refrigerant and a compressor where the temperature is raised to over 100 degrees and either blown across a fan coil for forced air or stored in a buffer tank for radiant systems. This heat is then delivered to the home through the duct work or circulator pumps
When its time for Cooling Season the system simply reverses its flow via a reversing valve in the GSHP. Hot return air from the home is then blown across a very cold fan-coil and it warms the refrigerant which is then cooled back down by the water or antifreeze loop essentially dumping the heat from the home into the cool ground (still and average 45-50 degrees).
