A professional home inspection is a visual inspection. The inspector can’t see through walls but should find defects that a trained eye can see. What if your inspector could see through walls??? Thermal imaging allows that to happen. The varriance in temprature can show failing circuit panels, leaks in walls (due to temp difference, not moisture) and levels of, or lack of, insulation in walls.
Typically used in commercial applications, the imager are expensive- over $10,000.
The best example site I have seen for residential use is here in Orem, Utah. A full thermal imaging scan ADDS $485 to a 2000-4000 SQFT standard home inspection.

The image is from the Fluke website. Fluke makes the machine that would probably be most appropriate to residential home inspections.
Is it worth the money and extra piece of mind? Inspections are buyer paid…
Would you choose an agent if it was the agent supplying the machine in conjunction with the inspector (thus reducing the cost of the inspection)?
Does the liability of missing something with the addition of the imager change?
