GAHT Video, This Time Slow No Music. Ground to Air Heat Transfer

This is a video showing the building of my GAHT system in Wisconsin, Zone 4A. Ground to Air Heat Transfer systems help warm the Walipini in the winter and cool the underground greenhouse in the summer.

Some folks were unaware of Youtube's feature that allowed you to slow down a video, so I took the liberty of uploading the SAME video, and slowed the frame rate down. I also left off the background music, and uploaded a new narration to match time with the slower playback.

There may be some other tidbits mentioned that were not included in the other video but the video itself is the SAME.

Note: This is not a tutorial. When building the Walipini, I took pictures and videos for my OWN reference, never considering the possibility of a Youtube channel. I submit info on my GAHT system for information and ideas, but if you have the money to pay a professional, I'm sure there are things he'd want to do differently.

Here are links to the fans used in the Walipini:

Now, that is not the EXACT version. The exact version appears to be discontinued. This is the closest I could find to the version currently used. I note that the brand name is different, but by appearances, its a match. Your mileage may vary, but if its essentially the same thing (and I think it is, but upgraded), I think you'll be pleased. YMMV!

This is the fan being used to blow the heat across the middle of the greenhouse:

It says it is 'quiet.' Yea, maybe, if its on very low power. If sound is an issue, definitely use the first fans I linked to. It was an issue for me, which is why I looked into to other options. Otherwise, it works fine.
