That's more what I was worried about; toxicity. The hottest the water could possibly get is 212F (100C) not nearly hot enough to melt even polyethylene. I'm not worried about the water, as I'm on a personal well, and there is no industry or commercial agriculture anywhere within 25 miles. So the only thing in the water is what nature puts in it.
However I cannot find any nipple waterers except for the vertical (from the underside) kind, plastic or metal. And since my birds are used to them anyways will the "Sparkletts bottle" type work OK with these heaters?
