Thanks for the feedback guys.
I did measure the outlet temperature this morning. Ambient temp was about 9F out. I had it plugged in for roughly 20 minutes. I could hear it boiling as I shot the picture below. But, low and behold, the outlet temp was...
I moved the IR temperature gun all around and 160F was the highest I saw.
But, I can hear it boiling! It sounds just like boiling water on a stove top, and the manual says it boils it too... So, now I'm confused haha.
Any ideas?
