Clamp mounted Heated Bird Bath is 60 watt thermostatically controlled.
This Heated Bird Bath is assembled in the Erva factory in Chicago. The thermostat and heating element are manufactured off shore. All other Heated Bird Bath components including the flame retardant black dish, 16 Gauge three prong grounded electrical cord (8" Long), insulation and the metal ring are made in the USA.
Some icing on the surface of the water is normal when temperatures are this low, especially if there is a breeze. Your birdbath is not defective if ice begins to form around the rim.
All Erva Heated Bird Baths are made with material certified as flame retardant.
