I happened to run into one of them a couple years back, and also happened to have a thermal camera on me at the time, and thought it was neat.

Temperature across a heat-powered fan on a wood stove. Note the nearly constant bottom section temperature, and a sharp 40F delta-T in the center where the thermoelectric pad is.

E: Sorry for the potato quality, but we're talking minimum budget FLIR Lepton here. And my MSX alignment is a bit off.

Thanks for sharing this. I'm surprised the hot side is only 82°C. Not even hot enough to boil water. However the fan is actively cooling the fireplace, so that does explain why it isn't over 100°C.
