Anybody know the reason why wood stoves pop, ping and tick when they're heating up? I've been burning for a couple of years now, but I really got to wondering about it the other morning while eating my Cap'n Crunch.
Why does a wood stove ping and tick when heating up

Expansion.
Correct. Mine will do this sometimes for half an hour until the flue gases reach about 1300 F. It sometimes creaks also as it cools off.
Holy Balls, that is HOT!!! have gotten 950+ but ever anywhere near 1300. It was glowing red at 950-1000 too......
Mine will for about 5 minutes in the AM when I stoke it up, usually chimney temps are around 600-700, when I close the door and go to work.

Yeah, but Wood Doctor is in Omaha... he has to burn the last bits of burglar out of the chimney...
My bones and joints do the same, and I'm only 45. I can't imagine what SS and tomtrees sound like in the morning - a crowd of people applauding I bet.

Yeah... no thanks! The temp gauge I have says over around 800 is an overfire.
I try to keep rapid temperature changes to a minimum in my Jotul. It's better for them.
Remember that I'm burning a modified cat combustor. That flue gas temp is measured right above the fire, just below the stove top, and before it goes up the chimney. Also, it only gets that hot when the temp outside is single digits or less and a NW wind is blowing, dropping the wind chill well below zero. My stove's fires love that. Most of the time the flue gas temp sits on 1100 F or less.

The ticking on my stove lulls me right to sleep in the recliner!
Expansion and contraction. I stoke my stove and it happens. A fresh load on a hot bead of coals and that heat isnt making it to the top half of the stove. My stove is sheet metal so I get a lot of movement out of it and it talks to me each loading.

Marshy is right. The noises come from expansion and contraction of various parts. If you have a part of your stove heating up or cooling faster than another part, the actual expansion will be different and where they meet will mean things sliding/rubbing. As metal moves across other metal it makes noise by things dragging. If every bit of your stove was completely isolated from every other bit, expansion and contraction would be silent because no part would ever rub against any other part.

Ok, this basically answers my question. I was fairly certain that the noise was coming from metal against metal rather than something weird like little molecules in the metal releasing gas (like when you crack your knuckles). I know it was kinduv a silly question, but my morning coffee hadn't really kicked in yet while I was listening to the stove warm up. Thanks all for the responses!
You young guys shouldn't have pops and pings yet....Not until you get old like me....lol.

Just thought I'd join the party with my two pennies worth...contraction/expansion.

Chairin'em for the sound
It's shameful to see a moderator joining in with the others to punk you. The sounds you are hearing are the souls of ancient, native people being freed from their woody prison. Expansion my ass. Ask yourself, have you ever seen a stove get bigger or smaller?
