Farm Innovators H-439 Submergible Stock Tank De-Icer | 1000W | Plastic Safe
The Farm Innovators H-439 Sinking Stock Tank De-Icer delivers 1000W of thermostatically controlled heating to help maintain drinking-water access in cold weather. Designed to rest at the bottom of a stock tank, it keeps the de-icer below the surface rather than floating among livestock.
A sturdy protective cage surrounds the heating element and permits use in plastic tanks according to the manufacturer's instructions. For winter watering chores, it provides an automatic de-icing option while you continue checking water levels and equipment condition.

Tank Selection & Compatibility
Select a de-icer for your tank's water volume, local winter temperatures, wind exposure and installation. Wattage alone does not guarantee an ice-free tank in every climate. Consult the manufacturer's wattage and gallon guide for your conditions rather than relying on a single universal capacity rating.
This listing is for the H-439 1000W stock-tank model, not the H-429 1500W model or P-429 pond de-icer. Keep the protective cage fitted as supplied and follow all tank-specific installation directions.
How to Use
- Read the supplied instructions and inspect the unit, cord and protective cage before installation.
- Arrange the required outdoor GFCI electrical supply and tank grounding as directed by the manufacturer, with a qualified electrician where required.
- Position the de-icer in the tank according to the instructions and protect the supply cord from livestock damage.
- Fill the tank with water before connecting power. Never operate the unit out of water.
- Check water availability, water level and equipment condition regularly during freezing weather.
Safety & Maintenance
Do not use extension cords. Follow all electrical, grounding and placement instructions precisely. Disconnect power before handling, cleaning or servicing the de-icer. Do not use damaged equipment or allow livestock to damage or chew the cord.
The manufacturer recommends cleaning every 30 days to prevent lime and mineral buildup. Maintain the heating element according to the supplied care directions. This product is a de-icer, not a heater intended to maintain warm water, and it does not remove the need for daily watering checks.
