On the full 8 foot wall, I have my radiant heat manifolds and will use most of that wall for the radiant heat plumbing and mechanicals. The wall to the right of that (if you were standing in the doorway, looking in), will have an on demand heat pump on the wall. I cant figure any other way to do it. I also need to have a water softening system and a well tank. That is a lot of real estate. On the other side is the electric panel, unless I can figure out somewhere to move it. The alcove wont work. You need 30 inches to place it in and 36 in front of it. The 36 was fine but the it is only 24 inches wide.
