GEO-THERMAL BABY, we all love a good hook-up. The rough in for our geo-thermal was completed 2-3-10 and stubbed into the basement. It is not rocket science or brain surgery...but there is a very cool "hot" tool involved. The well drillers left behind 4 -155' deep holes with black tubing sticking out. They brought their end loader back to break the frost and dig an "X" shaped trench between the four locations and the "Loopers" hooked them in a parallel system that runs the 'transfer liquid'
[ethanol] into the four holes and will return the fluid to the heat pump. Funny how a liquid can be both warm and cold without ever really changing temperature. Like so many things in life...it is all 'relative'. The tool that "welds" the tubing joints heats the sleeves up to 500 degrees, they join them, and "Bob's yer uncle" that's it. They simply melt together. They pressure test the joints and if there is an incomplete weld, the joints will whistle and sing. Our's were quiet. That's a good thing.
