You can definitely feel the heat coming out, like 116-118 degrees out of each one. Much to my wifes horror there was a cobweb above the one you could visibly see getting moved around when it was on.

Once I have the Mac back up and running Ill post some pictures, trying to do it from my smart phone is a bad joke at best.

Middle stud bay, only one that came close to a standard width, at one time there was a door in two different spots in that wall. Placed a piece of lathe between the pex and the foil insulation as it was heating the wall up pretty good on the bedroom side. Wasnt sure if it would cause issues with the drywall later.

One of the narrow ones, still managed to get at least 75 of pipe in it, just kept the coils closer together.

First one I did, have a 4x10 register top and bottom on the bedroom side of the wall. Used a piece of insulation board caulked in place top and bottom to seal the stud bay off.

Irwin 1 speed bit with a 10-12 extension was just barely long enough to get thru the beam into the basement.

Those speed bits just eat batteries once they grab hold.

Stripped the lathe and plaster on the walls then just the plaster on the ceiling as it had 6 of blown in above it. Screwed strips of 1/2 plywood to the ceiling joists to keep the lathe tight and act as a spacer, then added a 1 foil faced polystyrene insulation board, then screwed 2x4s over the insulation and fastened the drywall to that so ended up with a double dead airspace to add to the insulation value.

Picture of the temps partway thru a heating cycle. Diminishing returns seem to add up faster with this than say baseboard. 64 to 70 is pretty fast actually, little more than an hour on a room thats a little under 12 x 15,  out of curiosity once its over 73 it takes a LONG time to keep gaining any, might take as long to gain another degree once its over 73 as it did to get it from 64 to 70.

Im getting ready to start a similar project this summer if it slows down enough. I'll post some pictures when I get done. Have a room with a cast iron rad, but would like the wall space, so I'm thinking radiant wall. Floor is concrete so no radiant there.
Thanks for the pictures!
