I'm choosing between winter watering systems reliable to zero F, which won't happen often but often enough. I happen to have an unused 200 watt bird bath water heater (API Model WPU300). It has a built in 40F shut off themostat.
QUESTION.... Is 200 watt too much for a plastic bucket/cooler setup? The instructions don't say anything about materials for the reservoir, but being meant for bird baths the manufacturer might have just assumed one is using concrete, pottery, etc.
