Unusual image?	msm	1/6/2010
Can anyone help me diagnose this image? It was taken inside a log structure. The inside temperature was 68deg f and the outside temp was 28deg f. At first glance I think it's a missing sealant in between the log courses and then reflected sunlight coming in? It wasnt' a terribly sunny day though ... Also, if there was missing sealant then the cold air should have been coming in from the outside rather than "hot" air??

Is there a heat register below?
Re:Unusual image?	msm	1/7/2010
No, the heat is radiant floor heating ...

I agree that if chinking was missing or minimally installed I would have expected a cooler/darker area. I also wonder if you have something on the interior reflecting heat towards the wall that might be associated with this.

Again, the house has radiant in floor heating, but it's underneath tile and if it was reflecting heat it would be showing up in different spots on the log instead of just at the log to log connection.

In your visible picture it looks like a refrigerator just to the left. If so is there a chance the hot air off the condensor coils is getting between some of the logs that aren't sealed well enough?

Looks like a drawer on a stove . What kind of pie was it Apple or Pumpkin?
Re:Unusual image?	Brad Carr	1/13/2010
The wiring for the light switches probably run up the wall from the bottom. Warm air could be flowing up from the floor through the holes drilled for the wiring. It also could be heat conducting up from the floor . Regards Brad

Based on the infrared image, it appears that you are looking down toward the shot. With the gloss on the wood, this could very well be your reflection on the small 45 degree angle surfaces that were directly facing the camera. Did this anomaly move as you did?
Re:Unusual image?	msm	1/15/2010
These are all interesting theories. I don't think it could be coming from the refrigerator b/c the heat would have to travel through a solid post first ... however, I do like the theory about the wiring coming through the walls. There are definitely wiring chases coming from under neath and through the wall to the switch. If there was a slight gap between these logs some heat could be coming up through those holes and showing itself at the gaps. Is there a reason why it wouldn't be reflected sunlight from outside coming through? Thanks for the input everyone ... I will definitely use this forum for more diagnosis and help.

Typically you would not see the sunlight in the infrared spectrum. You would see the temperature that it creates on the surface. With the outside temperature being much colder than inside, you would expect it to be colder in that location from both air/heat movement toward the colder outside (heat conducts from hot to cold), and that the exterior air would lower the temperature of the wall components as compared to the interior temperature. Whatever is creating the anomaly is elevating temperature.

Assuming electrical radiant heating, heating wire may be carried up through the wall.

i agree with that...the unusual hot spots are due to geometrical changes .
