About the time I got into a new stack of wood out of the woodshed, I noticed that my temps were lower and the stove was a bit sluggish getting up to temp. I thought that my two-year white oak wasn't up to snuff, but there was no hissing, bright flames in the box and solid secondaries. My magnetic thermometer has always been about 20* off and I'm used to taking that into account. Today, I dug out my infrared thermometer and discovered that my mag. thermometer is 30-70* under depending on the temp. Thankfully, this time it's not the fault of the wood.
