Anyone ever experimented with radiant walls? My forte is radiant slabs and I've played with a few underfloor setups and radiant ceilings but never a radiant wall. I have been looking into it for my own basement in lieu of CI rads or baseboard to keep the area open, and had a customer call today wanting to do a floor overlay in his basement with an already 6'7" ceiling height so I suggested it to him also and he liked the sound of not having a 6'4" ceiling. I admittedly know very little about the whole transfer plates process, but it seems if a guy could notch the studs and fill the wall with transfer plates and X feet of tubing to be covered by sheetrock or whatever, should be able to heat the space similarly to an underfloor system. Mine at home will only require about 5k BTU to keep toasty, so I was kinda thinking of running a few loops of 1/2" down low, behind the wainscot, in the plates, 8" apart with a total loop of 250ish feet. Theoretically 1GPM should yield 7500 BTU at 15 degree delta T right? Or 15k at a 30 delta? Would be running boiler temp water through it and it'd only run when using the family room down there, otherwise the space stays 62-65 with no heat. Wall cavities have 2-3" of closed cell foam in them, so the majority ought to radiate outward and warm the space right? I'm really digging the idea if it works, hate to spend the money on radiant ceiling panels when the other route can be done at 1/8 the cost
