What Are Submersible Deicers and Why Do Large Stock Tanks Need Them
After years of dealing with frozen water systems, I’ve learned that submersible deicers aren’t just convenient—they’re essential for maintaining healthy livestock through harsh winters.
Understanding How Submersible Deicers Work
Submersible deicers use electric heating elements that sit directly in your water tank, creating gentle water circulation while maintaining temperatures just above freezing. The key is their thermostat control—they only activate when water approaches 32°F, making them incredibly energy-efficient.
Unlike surface heaters that fight air temperatures, these units work from within the water mass itself. This design prevents ice formation from the bottom up, ensuring your entire tank stays liquid even during brutal cold snaps.
Benefits of Using Deicers in Large Stock Tanks
You’ll save hours of daily ice-breaking labor while ensuring your animals have constant water access. Large stock tanks hold more water volume, which actually helps deicers work more efficiently—bigger thermal mass means less energy needed per gallon.
The real benefit shows up in your electric bill. Quality submersible units typically use 1,500 watts or less, costing roughly $3-5 daily during peak winter usage. Compare that to replacing frozen pipes or dealing with dehydrated livestock.
Winter Challenges for Livestock Water Systems
Frozen stock tanks create a domino effect of problems that extend far beyond just thirsty animals. When water freezes solid, you’re looking at potential tank damage from ice expansion, especially with metal containers.
Livestock consume 30-50% less water when it’s ice-cold, leading to reduced feed intake and slower weight gains. Cattle and horses need 30-50 gallons daily—hand-carrying water becomes impossible with large herds, making reliable heating systems non-negotiable for serious operations.
Key Features to Look for When Choosing Submersible Deicers for Large Stock Tanks
After years of dealing with frozen tanks, I’ve learned that the right features make all the difference between a deicer that works reliably and one that leaves you chopping ice at dawn.
Wattage and Heating Capacity Requirements
Choose 1,500 watts for tanks over 100 gallons. I’ve seen too many hobby farmers undersize their deicers, thinking they’ll save on electricity. Your 150-gallon stock tank needs serious heat output when temperatures drop below 10°F. Lower wattage units like 1,000-watt models work fine for smaller setups, but they’ll struggle in large tanks during severe cold snaps.
Safety Features and Electrical Certifications
Look for UL listing and GFCI protection as non-negotiables. Water and electricity don’t mix well, especially around livestock who might bump or chew on cords. I always check for automatic shut-off features that activate if the unit runs dry. Marine-grade sealing protects internal components from moisture damage that’ll kill cheaper units within a season.
Durability and Construction Materials
Stainless steel housing outlasts plastic by years in farm conditions. I’ve replaced three plastic deicers in the time my stainless unit has been running. Cast aluminum models offer good middle-ground durability at lower cost. The heating element should be enclosed in protective guards that prevent livestock from direct contact while allowing proper water circulation around the unit.
Thermostat Controls and Energy Efficiency
Built-in thermostats that activate at 35°F save significant electricity costs. Units without thermostats run constantly, driving up your power bill unnecessarily. I prefer models with adjustable temperature settings since water requirements vary by livestock type.
