I know it's normal for the stove itself to make noises when it heats up and cools down. I get the tink, tink, tink noise but this winter I've noticed that my stove pipe makes noise during the warm up period mostly. The noise the pipe makes is a little different but similar in that it's metal getting hot. I don't recall ever hearing noise from the pipe the last two winters and it was cleaned before I started burning. I posted a pic below and the sound seems to be coming from right around where thermometer is. I never had a thermometer until this season and thought it could to culprit so I'll take it off next reload and to see if I still get the noise. Anyone else ever get noise from their stove pipe?
