Allied Precision BDT250 Bird Bath De Icer Multiple Thermostat, 250-Watt

I have had this heater less than a year! I just ordered the plug protector and hooked it up and the heater ha a short somewhere and keeps tripping the GRFI plug, so will have to order another one. It was supposed to be guaranteed for TWO years. How do I get a replacement?

Hello. Is this likely to burn out (quit working) if water runs out in the birdbath? Thanks.

What minimum depth of water in a bird bath is required for safe and effective operation? i have a smallish bath that only ha about a 3/4 inch depth.

Can I use this in a 1 gallon plastic poultry waterer
