Heating a wardrobe?

I have to move my snakes into my room now :(

I like to have the fan on and whatnot so it'll probably be impossible to keep my room at 80.

I don't have a picture but the wardrobe is double doored and could fit their tubs in on a stand.

Is there I way I could raise the temp so my wardrobe is at the right temp?

Could I install heat lamps that hang down or use a fluorescent light?

Just looking for ideas.

Could I maybe run something like this:

On the inside on a thermostat?
