I'm going to go one step further and say you require a UTH or some sort of belly heat (glass vive?) WITH A THERMOSTAT.
Do NOT set up a UTH without a thermostat. You are asking for burns. It should be set to 90F.
I use these - they are nice for fewer snakes, and don't break the bank

You'll also want at least 2 hides in there large enough for him to get into yet small enough to feel secure. What kind of substrate are you using? You can go with something like paper towel, but in doing so you'll lose humidity which is necessary for proper health. You may want to create your own humid hide with store-bought sphagnum moss! Very cheap stuff, and you can use a plastic container to do this. I've posted a guide to making one on another thread.

PLEASE take a look at the care set up sticky on the main page. Very important to make sure you have proper temperatures before you actually get the snake, but I see you've done it backwards
You don't want night drops in temperature either. So, keep that heat bulb on 24/7. If it's also a light, swap it for a red bulb or simply a heat emitting bulb (that has no light).

Best of luck!
