The Homemade Heat Pump Manifesto

I mentioned I am having a contractor (steamroller :-)
build an addition, and I'm planning to DIY geo for the
addition and/or the whole house afterwards.

I asked the builder to embed 2 conduits - I think of them as portals - that I can use to put my HDPE through when I figure out how it will be done. (Even if I find a commercial
installer).
(Based on my lot, this location is a safe starting point -
the driveway stretches 60' to the left, yard is to the right :-)

The conduit below the frost line, and is sealed to the wall, and sealing and insulating will not be damaged by subsequent installation. I can fill the pipe with some kind of insulation (even air) until it is needed.
To follow the data model we use at work, Innies and Outies can be separate, and capacity is double from a single conduit.
Lowes sells the NDS pipe, but caps are not available there,
so I made caps out of 2 plastic plates, silicone, 2 plastic bags, and duct tape for a little structural support.
Of course, I can monitor and maintain from inside.

And, when I dig, by whatever means, it is not so close
to the house.
