ABSTRACT:
An immersible heater for an aquarium includes a waterproof, heat-resisting, flat plastic case which is tripartitioned in its interior, one chamber holding a flat coil carrier bonded or welded to the case; an upper chamber contains a leaf spring actuated by a bimetallic element; these chambers are separated by a thermally isolating chamber. The bias of the bimetallic actuator is adjusted by a sealed feedthrough screw. Current flow through the heating coil is indicated by a lamp covered with a thinner wall portion of the case. The front of the case carries heat-dissipating and -stiffening ribs; the rear of the case carries suction cups.
