It's ready to heat!

A few minor leaks added about an hour to the build but we got the hydronic system filled with water. There is a fair amount of air in the system but I got much of it out and all loops are flowing. 

I turned on the heat pump "just because" and got tubing warm to the touch. Manifold temp was up to about 85 with a 10-degree drop through the loops. Entirely inaccurate, I'll post actual performance data after we pour the slab and as I get the system dialed in. 

We are ready for our final set of inspections prior to starting drywall, scheduled to begin Dec. 1.
