I'm not new to smoking but just got a MES for Christmas. My old one was a charcoal smoker that I converted to electric. It was easy to access the wood tray to add or dump the burned wood with a small access door. This allowed me to manage the wood in/out process while only losing minimal smoke and heat. QUESTION: Do I need to dump the burnt wood chips before adding new ones in the MES? To do so I have to open the door and that lets my heat out. Advice?? Thanks. P.S. Any other MES tips and tricks would be great too. =) I'm sure there are plenty in this forum but there are soooooo many posts to sort through.
