Allied Precision Industries Bird Bath De-IcerThe Bird Bath De-Icer has a durable Teflon coated, compact aluminum base in a low profile design. Fins provide large surface area to make the unit 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. Cooler running, Teflon coating and flowing water all combine to reduce mineral buildup. Multiple thermostats allow efficient control while providing over-temperature protection. The Bird Bath De-Icer is safe to use in plastic bird baths and comes with a 10' cord.
