You really don't think there is a difference in 20C water on the

Okay, I'll play. How long does it take for the heat from a 60C motor to
transfer to the shaft such that the shaft is, oh, say 50C?

Thirty minutes? Ten minutes?

Seconds. Metal is a *very* good conductor of heat.

Then tabulate how long a disposal runs in a typical application.

Ten seconds? One minute?

Long enough.
