Another newbie, thinking ahead

[Bogertophis]

I was going to recommend the same thing. CHE's can also suck up the humidity.

Not only that but overhead heat of any kind is less efficient, since heat rises & a lot of heat never reaches the bottom, it just goes "up up & away".

I do use some supplemental overhead heat for some snakes, but my house is never that cool either, & just want OP to be aware, it might not be the best option for you (Midwest).

And Midwest, we commend you for doing your research & planning well ahead of time.
