Congrads on the Mini-Split.. I'm a big fan of Sanyo's 24k model..
http://ecorenovator.org/forum/projec...l-project.html I read your top post about the 'remote rustic cottage by the Gatineau river' and noticed you had the Long&Lat to 6 decimal places. So, don't be too surprised if you find your solar panels missing someday.. (Hint, might be a good idea to edit out exact locations if they are in 'remote' areas). Security of outdoor hardware is a big concern for me, since it would be an easy job for most anyone to find my exact address.. So, I'm always taking counter measures (like alarm systems, surveillance etc). Cheers, Rich |

Hi Rich,
I'm eyeing this Sanyo model too. Thanks for the comment on the location, it's safer that way. The panels are not left in situ when leaving for extended periods of time though. |

Here's a pic from the installation. What you see is the second layer of tubes on top of the first layer burried below. I did what I could with what I had, we'll see what I can get out of it.

Interesting. I too wonder how it'll work. I think I remember hearing about the air unit having problems with condensation in the lines? You pump warm air down there and the water just builds up.
In any case, good luck and keep us updated!

I read about one installation using long steel or iron pipes. (for better conductivity).
IIRC, a bed of medium rocks had been placed under the pipes, which had holes drilled in the bottom, to drain off any water that formed from condensation. However, the air input to that system was coming from outdoors. Where the air is sure to have more moisture.. If I had something like that in my yard, it would be full of water, due to the high water table we get here.. |

The AC is not needed a whole lot up here if other passive solutions are used. I see more use for the loop in the winter, hoping to get the heat pump working well into sub zero exterior temps. I however plan to have a way to pump condensed water out of the tubes if it pools and cause important flow restrictions.

I just had one of these installed last week:
Fujitsu 12RLS - 12000 BTU 25 SEER/12 HSPF heat pump Good specs and the warranty in Canada is 10 years on the compressor, parts and labor. I'm going to be setting it up with the ground loop and a blower for next winter. The 3000 kWh a month we've had this winter have been bad enough. |

So, you plan to pump cold outdoor air, underground,
where it will be warmed up to 5C (41F) and fed back up, into the air intake of the 12RLS?? Unless you have a very active (and high) water table, it seems like the soil around those tubes is going to get mighty cold. Pretty quick. Please give us some more details about this system..

That's it.
Experimentation will tell the true story. The loop is comprised of ten, 4 inches across, fifty foot long corrugated tubes buried 6 feet underground. I'll log the inlet and outlet temps along with the mass air flow to see what I can get out of it next winter. I spent only $300 on the loop. From the calculations I did before proceeding I'm very confident I'm going to be able to make up for it in a few years. |
