You might want to consider a different gas other than co2. Argon, for instance, has a lower heat capacity. Vacuum provides an insulating propery to furnaces so the heaters perform better. Argon more closely resembles vacuum in this respect.
Be sure to allow the gas to vent as the temperature rises so as not to overly pressurize your chamber.
Best of luck.
