Im new to the site....Last evening I was sleeping so well and all of a sudden BANG...like a small caliber gun...even set off the glass breakage system of our security alarm...couldnt find anything all over the house and all we could come to reason it was the heater...Now I think back on it and yesterday evening as I was starting a fire...my heater seemed to groan and stretch even more than usual with a new fire...then this evening my heater makes almost a constatnt slow....click click po...tink clank pop. click,,,etc etc but then it will stop and be silent...then it may resume its complaining....I have a cracked refractory shoe that I am waiting to arrive...but I have continued burning my heater....has anyone else ever experienced this horribe sound coming from their heater? Ours is a vermont castings defiant noncat......Please help if anyone has any suggestions
 
I have a Defiant non-cat and have never had that sort of problem. My stove will back puff every once in a while but that makes sort of a thump noise when the lid lifts and drops. Strange.
 
Give the stove a very thorough examination for cracks, internally and externally.
 
What wood are you burning? I had some old growth tamarack several years ago that was full of "sap pockets". Thought there was a twelve gauge going off every now and then. Pockets were from "shake tears" in older trees caught in a huge wind. Locals thought no big deal, but it put me under the bed a few times. If your stove is real hot and there is a good seal it will really fart. Other times it will look like a propane torch going off.
 
Someone was telling a few weeks ago about a backdraft his father's Hearthstone experienced - sounded like an explosion and shook the house. The stove actually shifted position a fraction of an inch.

I do hear popping from pine, but nothing like a gunshot.
 
I sometimes here a similar sound from my insert when the heat shield (sheet metal) expands during a hot fire. It can wake me up out of a dead sleep. Just some food for thought
 
thank you for all responses so far...i did remove all refractory and examined the heater...nothing......the puffing or backdraft seems very logical
 
I can tell my oslo's approx. stovetop temp. on a full load with the air open just by listening to the clicking and popping noise of heating up.

I had a Defiant, and my guess is this. They are known for warping ash pans. I bet that ash pan was warped/twisted and when she cooled down she "snapped" back into original form and let out a big old BANG!

Kid you not, I've heard that before and it really could be the case here. Metal does strange things and makes interesting noises when it heats up and cools down.
