Abstract
An immersible, floatable aquarium heater is provided, with universal mounting bracket which will accommodate both the old and new types of aquarium construction. The heater includes a sealing cap incorporating integrally the control knob spindle and the power line for the heater. The arrangement provides a triple seal to protect the vital heater controls from high humidity in the aquarium environment, with the seal preventing leakage in case of accidental submersion of the entire heater. The control knob of the heater includes a tamper-proof feature to avoid adjustments beyond a 10.degree. range, unless actually required.
