I keep my house temps in the low 70's ( 70-73 ) because my son and I both have bad sinus problems and to hot causes us nose bleeds. I place the heater about 2' from the front of the rack. I also place something on the top of the rack ( for now a blanket ) to help hold the heat in there also. The temp on my ranco stays at about 79-80. I have my Helix set at 93 and have my probe taped to the bottom tub's flextape w/ clear packing tape.
My tubs stay at 80.9 to 82.9 cool side to 91.9 to 93 hot side.
I do notice that the bottom tub will be a little cooler and the two middle tubs warmer and the top tub right in the middle temp wise.
And this is with my rack on an exterior wall, no less.
I do plan on this winter putting some insulation on the back wall of the rack and maybe lifting my rack about 6-12" of the floor.
The bottom tub stays cooler because of draft and that cooler air flows to the bottom of the room.
Hope this helps
