It was a little chilly today, so we fired up Paul's propane heater.

Since we were nearing the back wall with our layout, and in trying to keep the heat in, we moved the spool inside.

Paul and Bob working on the layout in the "bedroom" area.

After all of the loops were run to and from the temporary wall, the floor in the Utility Room area looked like a giant creepy bug from a horror movie.

These two loops in the "bedroom" area, along with a smaller loop in the "bathroom" area make up one zone. If we ever finish the basement, the heat for the bedrooms will also control the heat to the bathroom.

When it came to the double piers, some runs could go right between them while others had to go around.

Bob's nice cleanup job of the patio. We just need to grade it to get it ready for concrete in a couple of weeks.

Paul and Jeff labeled each send and return line on the temporary wall, so we would know exactly how to connect the manifolds when the time comes.

The last thing to do was to cap one end of each of the 9 loops. This simply required a brass plug...

...and a crimp ring. We're now ready for pressure-testing tomorrow.
