I use an electric space heater without putting it into a T-stat, its built-in, and that works great. I monitor it with an Acu-rite. I'm not sure how much it will end up costing. Also, your herpstat pro might not be able to support the heater due to thier high wattage, mine is 750-1500 watts so my herpstat 2 won't work for it...
