I'm planing on building my first cold smoker. I hope to start tomorrow. My plans are to do a varetion on the refredgirator smoke house, and heating it with an electric hotplate. I see in most of the cold smokehouse plans that it is suggested that you locate the fire pit at least 10 ft from the chamber in order to keep the temp.down. is it still necessary to do this with an electric smoke house. My thoughts are that a the hotplate shouldn't be as hot as a burning pit, so I am hoping I will be able to set the old cooler (I'm using an old ice chest like bag ice is sold from as a chamber) on blocks, cut a hole in the botom of it and locate my smoke source in the hole. Will it get too hot with this setup?
