Just got my IR. I was burning for almost two years in a lopi cape cod without measuring any temperatures and I was quite happy. This year I discover hearth.com and learned a lot from it THANK YOU ALL. So today I started my fire and of course started playing with the IR. Here is what I found out at the temperature by feel where I usually would start shutting down the spot right above the door (not the door frame) was reading 350 I took a reading of a air tube that was only 680 the door frame it's self is 480. So all that time I was running it way too cold but still getting my house nice and warm.
