Radiant floor heat

Here is the plan for the first floor underfloor radiant heat. The orange & green zones should be ~150 ft of pex and the red & yellow zones should be ~250 ft. A manifold with flow meters will balance the lengths and provide even heat distribution. I’m calling the areas zones but they will not have an independent ability to call for heat.

The first zone, orange in the plan, is in the dining room. I started here, it took about 1 hr to pull 50 ft of pex. The obstacles to work around were quite annoying.

The second zone, green, is a bit of the dining room and then the kitchen. I pulled this whole length in half the time as the first.
