just bought a zoo med under tank heater

I would not put it on wood it will mess it up with the heat and can cause fire.

I have never had a problem with it and all my tanks are on wood of some kind. Both painted and non. Finished and non. Hasn't messed up the heat production either. The only time I have seen that is if the aquarium is resting directly on the housing part of the UTH which is where the cord goes into the UTH.
