I have a Char-Broil electric smoker that I purchased for $30 and the thermostat went out. New thermostat is another $30 and I really want to get a Masterbuilt 30" anyway so I will not relplace the thermostat. But, I was wondering if I could use a small hot plate in the Char-Broil for a cold smoker? Any recomendations on wattage of a hot plate? Will it get to hot?
