I have a stack of cast iron pans in the corner of my stove (for lack of room) and I put my plates there in the general vicinity of all the heat. Warm enough!

I used to work in a kitchen as my first job when I was like 16 and those heat lamps were great. Fancy restaurant in a small motel. I used to have to do prep, dishpig and room service. Ex dot the chef's would sometimes throw the room service lids on and then put the whole thing under the heatlamp. So we had all these plastic slightly warped / bubbled lids 6 dishes on a tray, 2 wide, stacked 3 high, soup on top wobbling around, and outside stairs to get to some rooms, no elevators.

Chaotic.
