Pex Layout in MBR

1/2” Pex-A. Mr Pex brand, nice flexible stuff.

4 loops, 165’ each, 6” on center, Counter Flow pattern.
This allows for very low pumping electricity usage due to low head loss.

4 heating zones in house, each has its own Grundfos Alpha (about 5 Watts on low)
Continuous circulation in heating season, about 8 months a year.

Master Bath along North wall is its own zone, 1 loop, so it has its own thermostat so I can keep bathroom 15* warmer than Master bedroom, shower has a heated seat.

I have decided to cover the inside wall and gable ends with R-15 3.5” Roxul rock wool reaching an R-40 total.

The downstairs ceilings are 10’ high.
I’m using 10’ LSL’s which are a manufactured 2x4
They cost more but are straight, good luck getting a straight 10’ lumber yard 2x4

I got the concrete slab poured for the downstairs floor.

1440 ft2 full floating with 6” of type 2 EPS under it and 7” around entire perimeter.

Old sub-contractor used young labor & did a nice smooth job, he said that the rich mud was easier to finish. I got it done about a month before Winter set in.

About 5" thick on average, high strength 5,000 PSI & double fiberglass
(which are now smaller strands than they used when i last did this)

Ran a 1/2" rebar (#4) all around perimiter about 5" in from edge.
The heavy gauge 6" x 6" remesh in the slab was handy for attaching the pex with zip ties.

I tried to run the 1/2" pex at 6" on center but with all the sweeping turns it averaged 7”

I reduced the doorway heat loss issue, to some extent, with EPS foam between slab & outside concrete wall and a 2" x 12" PT board on top to bridge the gap.

The 2x12 at the outside edge sits on 1.5" angle Iron that is attached to the inside of the 8" concrete wall with 3/8" RedHead anchor bolts, the inside edge of the 2x12 sits on top of part of the concrete slab that was allowed to run under it for a few inches, very secure.

I will need to dress it up on top with something that won't conduct too much heat out.

Upstairs 672ft2 is heated by Pex suspended under the 3/4” Advantech subfloor.

This heat transfer from the Pex via convection & some radiation to the subfloor is less efficient than conduction in a slab & the water temperature needs to be about 40*F hotter (no good for solar or a heat pump)

Most is spaced at 4” on Center and is 2” to 6” below subfloor and works mostly by convection.
