I use aquarioum heaters in my etch tank of Ferric Chloride, you can 
more less bypass the thermostat.  Mine have a plastic cap on top 
that covers the thermostat control.  It will have a stop on it but 
you can bypass it and turn it up more.  I have two in a 5 gal. tank 
and heats it up to over 120 deg.F. that is as high as I can measure 
so not sure about what the real temp. is.  Takes it a little while 
to get it there but they will get it plenty hot.  Well etch a 8" x 
10" or 8" x 12" board in less than 8 mins.

The heater that I have I got at Wal Mart.
