I've read that it really doesn't matter. The heat and moisture loss have a linear relationship, so there is nothing to gain by changing the temperature, energy-wise.

I'm sure there are minute differences because the dryer may have less heat loss at lower temps and the motor energy consumption is a function of time only.

There is also the matter of infiltration losses in the rest of the house because the dryer is sucking air out of the house. Longer run time means more loss. Maybe high is actually most efficient, then?

It'd be interesting to see measurements of all this. But really, I just want a heat pump dryer.
