API 11.25 in. H X 4.75 in. W X 4.75 in. D Bird Bath De-Icer/Heater

Attract wild birds to your yard or property year-round with this bird bath de-icer with an aluminum base. Now you don't have to store your bird bath over the winter. Just add this De-icer and it will keep your bird bath ice-free all winter long, even in sub-zero temperatures. The BDT250 has a durable, nonstick-coated, compact aluminum base in a low-profile design. Fins give this de-icer a large surface area, which allows the unit to run cooler while putting out the same amount of heat as conventional de-icers. Channels within the base promote water flow as the water is heated, which helps to eliminate mineral buildup. Multiple thermostat control offers increased efficiency.
