Elevating a glass tank with a UTH underneath

[The Serpent Merchant]

I actually do elevate..... tank sits on 2- 1x1x12 pieces of wood. I thought this would be better for airflow and avoid pinching any cords?

Avoiding pinching cords maybe, but there isn't any need for airflow.

The reason zoo-med/exoterra and the like say that you need air flow is because their packaging says that they don't need to be regulated. (Which is a blatant lie to sell product) When unregulated a UTH would overheat much faster without any airflow, but when regulate by a thermostat it is impossible to this to happen in the first place. Think about it this way:

If the UTH started to overheat the thermostat will simply reduct/cut power going to the UTH thereby preventing the the UTH from overheating in the first place. When properly regulated a UTH shouldn't get much hotter than 100 degrees F (105 tops) compare that to an unregulated UTH which will hit 130+ F easily
