We place our bathroom ceiling fan on the floor blowing into a false wall and across the heat tape.
The heated air escapes out the top in the back and is pulled across the tubs to the fan on the bottom to repeat the circulation.
No hot spots and temps within 1 degree top to bottom.
No exposed heat tape makes it so tubs can but placed anywhere in the inc without being up against the heat tape.
Heat tape against back wall before adding false wall...
Fan on bottom with heat tape covered by the false wall...
Time for tubs and eggs
Last season we had flexwatt on each side and the fan on the floor of the inc blowing against the back, it worked very well(100% hatch rate) except the tubs were warmer on the ends than in the middle so we went to a false wall to hide the flexwatt.
