What 'outdoor-rated' actually means
An outdoor heated water bowl needs three things a normal bowl doesn't: a fully sealed heating element, a weather-resistant cord that won't crack at −20°C, and a thermostat that handles wide temperature swings without burning out.
Our bowls are built specifically for this. The cable jacket stays flexible to −30°C. The heating element is potted in food-safe resin and sits behind a stainless-steel basin. The thermostat is a wax-bulb design with no electronics to fail.
