The plan is 12 feet, every additional foot beyond six was worth 1 degree fahrenheit for a guy in Maryland. I'll have to see how big of a "V" is required to go that far in wet ground. I can make a huge mess at the base of this hill so if the hole is tapered enough on the sides, going that deep shouldn't be a problem. Horizontal geothermal trenches are installed at 5-6 feet with back hoes like you mentioned. Depending on the location and soil it seems like they would make a good silent radiator but the temperature swing might be too much.

I'm not 100% sure of the trench length yet because it'll depend on how wide the trench is and how much I overlap the coil loops. The longer and less overlap the better for cooling but I don't know if that will be necessary with less than 1000w of heat going into the loop.

The plan is to do two passes in the hole, with a couple feet (maybe 18", I don't have data to support either option!) of dirt separating the layers. The warm water will go down into that top layer and exit colder from the bottom return one. The length and density of the coils will most likely come down to how easy or hard the excavating goes on the big day.

Here's the link to the ground temperature probe results from Maryland. The guy who didn't isn't sure if his probes at the bottom of the tube are insulated from the others enough because the temperatures are higher than the prevailing wisdom says they should be. Also his long term data isn't collecting correctly unfortunately. I'm going to try and set up a 1-wire system like he did so there will plenty of hard data on this projects results.

Condensation will become a problem at some point. The 1-wire controller pc could be programmed to monitor humidity and turn on de-humidifier (with drain valve) in the summer. The automation capabilities are quite amazing.

Words cannot express the shear awesomeness and how much of an epic win this is! Sub'd!

I saw one a long time ago, on some TV show. The guy kind of screwed up as he didn't bury the coil deep enough and it froze and burst.
