Here is the manifold for one of the radiant heat zones. There will be three zones in the house. Each zone can have up to 5 circuits (a pipe that starts at the manifold, extends out through the floor and returns to the manifold) and a circuit can go up to 300'.

I thought this manifold was a truly amazing piece of equipment. Steve tells me that there is a lot of fine-tuning we can do on the system once it is up and running, using the controls on the manifolds.

Once the pipes are installed, they have to be pressurized and under pressure during the inspection to demonstrate that they can hold the water without leaking. (Leaking would be very bad.)

Here is a picture from the bank to the east of the house showing most of the pier holes for the carport. The carport has been pivoted away from the house slightly because Janver had a grading contractor come in and slope back the bank behind where it will go. The new position will be much easier to drive into that the original one would have been because it is more open toward the driveway.

Here is another overview picture of the floor plan. The two men are standing in the laundry room. From them clock-wise around the courtyard are the master bath, master bedroom, kitchen/family room, dining room, living room, foyer, guest bath, guest room and library.

They will not put down gravel under the void-form on this slab as they did on the barn and guest cottage. As far as I could see, that was just a big waste of money. If they want a void beneath the slab, who cares what is below the void—the whole point of the void is that there is nothing touching the slab bottom. My understanding is that one of the engineers required the gravel then and has now seen the light.

Here is the master hook up for the hydronic heating system. Pretty amazing isn’t it? Once the preliminary plumbing is finished, the rebar mat goes in. The heating pipes are woven into the top mat.

This is going to be the drain for the bathtub in the box in the barn. There needs to be a depression around the drain of a bathtub (who knew?) so the plumber has this little pan, which will make a depression in the concrete when it is poured.

These pipes are for the hydronic system and taking water to the manifold in the west wing of the house. That piece of plywood you see floating in the middle of the background of this photo is the temporary mounting for the manifold. This one will live in the wall of the front hall coat closet.

The pipes in the very foreground are for the kitchen sink, which will be in an island. The electrician came today, as well, to put conduit for electric and cable for the island as well.

Here is the little pan for the guest bath tub drain. The thick, white pipe to the left of it is the toilet drain which was laid before the grade-beams were poured.
