Geothermal - Part 2

After the trenches were dug, then the tubing had to be connected together.  This was done with the aid of a little piece of equipment that heated the ends of the tubing to a very high temperature.  I'm thinking they told me 500 degrees!  Once heated, the ends of the tubing could then be put together with various kinds of connectors.  These 2 guys had the dirty job of having to get down into the hole where all the trenches came together and join the pieces of tubing together.

Once this was done, then they covered the trenches.  As you can see, these take up a lot of space and it will take a while for the ground to settle.

The last step is to bring the tubing inside the house and connect it to the heat pump units.  Our main unit is in our basement.  Here's a picture of the finished system:
