This is more of a rant than anything but what the heck! Two days in a row I've caught my Englander 30 going Nuclear without a reason I can figure out! I start a fire at 5:45am. I am using Oak that is 2+ years old at around 20%. Some are dryer some are wetter. I load about 7 medium splits in there and a half a SuperCedar. The door stays cracked for about 5 minutes (10 tops) while the fire gets going. I make my coffee, close the door and gradually damper the air down step by step. I drink my coffee and eat some toast while monitoring the fire. I then head upstairs to take a shower after things have settled in. This is usually around 6:15am or so. At this point the air control is 95% closed, maybe a 1/4" or 1/8" open. The surface temp of the stove is about 550F (IR gun), stack temp in the double wall is about 500F (probe thermometer). Secondaries are lit but lazy. Should be good for a nice long burn no?!?!? This is how I normally manage my fires and it normally goes just fine.....except for the past two days. Yesterday I thought it was a fluke but the same thing happened today! I get out of the shower and go downstairs only to find a NUCLEAR INFERNO Secondaries are massive and the whole load of wood is ablaze. Surface temps are 850F and stack temps are 1000F. Yikes I then close the air completely and turn the blower on high. After 15 minutes the surface temp is down to 700F and the secondaries are still active....but what I'd consider normal. The main problem about this is the house is now 88F and uncomfortable and the load of wood is going to be spent by 10am! What gives!
