A lot of people do this, you stick the thermostat probe somewhere in the room to measure the ambient temperatures. The thermostat then turns the space heater on and off to keep the room at the desired temperature.

from the reptile basics site:
The Ranco/Johnson is good for about 1500 watts and the VE-100 for 700 watts. For most users this does not make a lot of difference. The one big exception to this is if you are using a thermostat to control a room heater. Generally oil filled space heaters work well in reptile rooms but use about 1200 watts of power. For this application the Ranco or Johnson is the obvious choice. For rack or cage use the VE-100 offers good looks, silent operation and more than enough power capacity to get the job done!
