Basic question regarding Geothermal – how to calculate loop lengths
I have a basic grasp on the general principles of Geothermal – capturing the consistent ambient temp below ground.
It’s clear that there is a need for long lengths of pipe in order to equalize the temp – in simple terms, say water coming in at 40 degrees and exiting the loop at 50 degrees.
How does one determine the needed lengths of pipe to achieve the full benefit of the underground temp? I realize there are a variety of environmental factors, was wondering if there’s a basic calculation to get some sort of approximate range.
