JXJHOVV’s 500W de-icer solves a simple, critical winter problem: frozen livestock water. It’s a straightforward tool with a clear job. The automatic thermostat is what makes it reliable. You plug it in and forget it. The unit only activates when the water temperature drops near freezing, which saves energy and prevents overheating your tank.

The 500-watt heating element maintains an ice-free opening in temperatures down to 10°F. In practice, that means a reliable drinking hole for chickens, horses, or cattle in a standard 5 to 25-gallon tank. The heavy-duty, submersible casing feels solid and the flat profile helps it sit securely on the bottom. It’s a set-it-and-forget-it piece of hardware for a homestead or small farm.

Just note its scale. This is built for troughs and stock tanks, not massive ponds. The cord is a standard length, so you’ll need a protected outdoor outlet nearby. For its intended use, it delivers consistent, hands-off performance through the deepest freezes.
