Potentially cold

Tony_23

Went to a new build yesterday. TG it's not finished.

"Plates", the style of which are made of flashing. 1/2" tubing installed by HO threaded thru holes 1" or smaller, drilled so close to the top of the joists they look like they're notches, not holes. Loops are 300' +/- 15 %.

The best part is the Great Room. Windows facing due South, .30 U-factor, the whole wall close to 400 sq.ft. of glass. 400 sq ft of floor that somehow is supposed to emit 35 BTU/sqft. 8" centers. 143* water, 20*DT. Also, 1800 ft of tubing is supposed to be magically crammed into 400 sqft of floor and on 8" centers to boot ! It IS a tile floor, but I really don't think so :)

Oh yeah, it was to be insulated from below with the magical reflective qualities of dbl bubble foil, period :)

And we wonder how radiant gets a bad name.........

you forgot to mention that they are adding a Tom Swift jr and his atomic radiant heat magnifyer for those really cold days...
