Coolant wanter can get pretty nasty.  We back-of-enveloped using warm water 
from our water-cooled systems via a heat exchanger to malt barley for beer some 
years ago, but the output water was too cool to be of use.  On the other hand, 
people are growing much more comfortable with using much warmer water to cool 
their systems than we had imagined at the time, so maybe it would be worth 
revisiting?
