Just to clarify - the bird bath heater DID keep the water in the bucket from freezing..just didn't keep the necks to the cups open because they don't heat the water above about 45 degrees. They are 250 watts.
The fish tank heater I used heats the water hotter which, I think, is why they were better at keeping the cups open. Mine was 50 watts (in comparison to the 250 on the bird bath heaters). But they also have higher wattage up to 250 depending on the size of the tank you're trying to heat. Aoxa MAY need a higher wattage due to the extreme temperature but she won't know unless she experiments.
Aoxa - Strombergs told me those feeders weigh 4.86 lbs. That might be weighty enough to stabilize it!
Please give us a report on stability as soon as you use them for awhile!
