Unlike other birdbath heaters that use an exposed electrical element to warm the water, the KozyBird Oasis™ features a sunlight-absorbent polymer with a hermetically sealed heating element for years of safe, reliable use. An intricate network of heating wires permeates the entire surface of the product, assuring a life-saving source of open water down to sub-zero temperatures. And it uses just 95watts/120 volts, so it costs just pennies a day to operate.
Perhaps most important, your KozyBird Oasis™ is exceedingly safe to operate. The heater and thermostat are sealed in a single-piece polymer resin, eliminating risk of liquid penetration. There are no exposed electrical elements, so birds can walk on the heater in complete safety. (Birdbath not included.) By Allied Precision Industries.
