Abstract: A water heater for home aquariums, the device being adapted for partial immersion in the aquarium water. It comprises a casing the upper portion of which has a multiple-size bracket for attachment to the rim of a selected aquarium, the lower portion housing a thermostat-float switch assembly electrically connected to an electric heating element. The said lower portion is defined by an apertured shell serving both as a water-permeable housing the protective shield for the heater and its control components. The water to be heated enters the interior of the device for coaction with the heater components, thereby performing the heatcontrolling operations itself by actuating a switch-operated float member. The device is adapted for attachment to aquariums of different rim thicknesses by said bracket which is of specially stepped construction.
