Would this work?

I have heating cable for my pipes that I don't need any more would I be able to use it to heat up a 4x2x1 wood cage? Place it under tile.

It looks pretty similar to the heat cable in one of my racks so my guess would be yes. I really dont know for sure though. PM TheSerpantMerchant. He'll know.
