I've been using the same submersible aquarium heater for 19 years and was
sweating it's demise for that very reason: the new ones have a limit that
prevents cooking the fish.

A friend and student provided peace of mind by kindly giving me a
terrific tray heater that has no moving parts and includes evaporation
protection that cuts the heat if the tray solution level drops too low.

Doran Enterprises has the Temperature Control Model TC-750 at the
following:

This unit is adjustable and will let you crank your developer temperature
to 115F and higher. I use it to heat water in a larger try in which my
developer tray rests on four stainless Nikkor reels (gotta use those old
phylm things for something). It's a standard double-boiler setup.

Hope this helps!
