tweak it ;-)

"more power"...

or make it yourself from a lab glass tube and some resistance wire.
most likely cheaper and maybe you can not take the commercial unit
apart without damage.

i filled the glass tube with silicone, thermal epoxy would be better.
however i do not use the heater (HCl and H2O2 needs none).

you could also glue a "second floor" in your etch tank and put the heating 
wire there,
or a heating plate. (depends on tank material also).
