Heating an enire room?

[Vengeance]

I'm moving to a new house in July (YA ME!) and since me and my girlfriend have lived in an apt for the past 3 years I never had a room to dedicate to my animals. I'm picking up at least 2 more ball pythons and what I want to do is dedicate an entire room to them.

Now the reason for this is so that I can better control the ambient air temps in the cages. By heating the whole room I’d be able to maintain proper day and night time drops and the like but my only concern is that it may damage the room itself. So my question is when heating a room to 85oF are there any precautions or perpetrations I need to make on the room to make sure no damage is done to the room. Also same questions goes if I wanted to control the humidity in the room as well.

Thanks
