Geothermal or ground source heat pumps (GSHPs) are electrically powered systems that tap the stored energy of the greatest solar collector in existence: the earth. These systems use the earth's relatively constant temperature to provide heating, cooling, and hot water for homes, schools, churches and commercial buildings. A closed loop field absorbs the heat from the polyethylene pipe buried at least 5' below the surface and transfers that heat through the glycol solution to the building. It's safe, long lasting, low maintenance (change a filter) and will save you thousands of dollars over the life of your home or building.

Boreholes are drilled in a grid usually about 15' apart, 205' deep. Sunaqua Inc will headers the pipe into the building, add the polyethyl glycol and flushes and purges the system. Your or our mechanical or heating contractor installs the heat pump and duct work inside the building. You are ready to experience comfort and savings. Your home or building will be warm in the winter and cool in the summer, run quietly and will save on interior space for mechanical equipment as most is under your yard, driveway or parking lot or possibly under a football field.





The technology relies on the fact that the Earth (beneath the surface) remains at a relatively constant temperature throughout the year, warmer than the air above it during the winter and cooler in the summer, very much like a cave. The geothermal heat pump takes advantage of this by transferring heat stored in the Earth or in ground water into a building during the winter, and transferring it out of the building and back into the ground during the summer.


A Closed loop Ground Source Loop Field looks like this drawing underground. Typical boreholes are 200' deep in a grid 15' apart. They are headered into a manifold and brought into the building to the heat pump(s) which circulate the heat in zones throughout the building. Radiant heat or forced air heating or a hybrid of both can be used.

Water or antifreeze solution is circulated through plastic pipes buried beneath the earth's surface. During the winter, the fluid absorbs heat from the earth which is about 50 degrees year around and carries it through the system and into the building. It's much more efficient to bring 50 degrees to room temperature than to take outside air and heat or cool it to room temperature.

Pipe has 50 year warranty. Heat pumps are vary low maintenance…just change filters. No boilers license needed. Takes little space in building.

During the summer, the system reverses itself to cool the building by pulling heat from the building, carrying it through the system and placing it in the ground.

You can use your yard, parking lot or ball field for your well field. Murray High School used the student parking lot for their wellfield. They saved $1M in construction costs in the size of their mechanical room and they never shovel or plow the parking lot as the grid of geoexchange flowing to the school below the surface keeps the parking lot snow free.

Heat pumps work like a refrigerator compressor, transferring heat, not making heat or cold. That's why it's so energy efficient.
