raising ambient temp in my tub

[tttaylorrr]

I am not sure they provide adequate radiant heat for the air in an enclosure. That is actually a good question and one I would be curious to know. I would assume heat tape in a tub would be a bad idea (not sure if sticking it on the top of the tub lid would radiate heat at all)

my idea was taping it to the short side (cool side) on the outside of the tub and using styrofoam to try and insulate the heat.

i know heat tape isn't meant to affect ambient temps but people use it in racks and other applications with success. i have never used heat tape before so i was hoping someone with experience could chime in and let me know if this could work.
