MQLD Rubermaid 100 Gallon Stock Tank Cover

Designed to fit stock tanks around 54″ long by 35″ wide and approximately 6″ deep, this insulated cover helps preserve water temperature and reduce ice formation. An upgraded zipper at the seam allows partial access without removing the entire cover, which is ideal for horses or livestock that need quick drinking access. The bottom uses bungee cords to secure the cover during windy or extreme weather. Overall, its emphasis on a snug fit and easy access makes it a practical option for outdoor water systems.
Equine Thermo Water Bucket

The Equine Thermo Water Bucket combines an insulated floating top gallon with a freeze-proof design, suitable for maintaining hydration in barn or stall settings. Its components are described as impact resistant and durable, which helps it withstand daily use. This option focuses on maintaining liquid water despite cold temperatures and is compatible with standard barn infrastructure, offering a simple, reliable solution for year-round water access.
MQLD Rubermaid 150 Gallon Stock Tank Cover

This larger stock tank cover is sized for up to 150 gallons, measuring about 61″ L x 42″ W x 9.5″ H. It includes an upgraded bottom bungee system to keep the cover secure in harsh weather and features reflective strips on the front and back for nighttime visibility. It’s a strong option for bigger troughs used in freezing climates, helping maintain water cleanliness and temperature more effectively than standard covers.
Behlen Country 100-Gallon Stock Tank

This galvanized stock tank includes a 1,500W floating de-icer, designed to remain thermostatically controlled and only activate when water begins to freeze. The 20-gauge galvanized steel with a zinc coating offers corrosion resistance for outdoor environments. It provides a complete year-round hydration solution by combining durable construction with automatic ice prevention, enabling steady water access in cold conditions.
API Heated Bucket

The API Heated Bucket provides a compact, 64-quart capacity with built-in thermostatic control and overheating protection. Made from impact-resistant polyethylene, this heater-equipped pail is designed to minimize ice buildup while withstanding daily barn use. It’s suitable for smaller groups or individual horses needing reliable warmth without larger trough infrastructure.
Buying Guide
- Size and capacity: Match trough size to your herd and space. Larger tanks require bigger covers or additional de-icer components to prevent freezing across the water surface.
- Insulation quality: Thick, durable insulation reduces heat loss and slows ice formation, which lowers maintenance and water turnover effort.
- Access and maintenance: Zippered or easy-access covers simplify refilling and monitoring water, crucial for horses that drink frequently.
- Weather resistance: Look for reflective strips, secure tie-downs, and weatherproof materials to ensure the product stays in place during wind and snow.
- De-icer compatibility: For galvanized or plastic troughs, choose an energy-efficient floating de-icer or heating bucket designed to prevent over-heat and minimize electricity use.
- Durability and safety: Materials should withstand daily use, UV exposure, and impact. For metallic troughs, galvanized steel offers longevity, while plastic options may be lighter and portable.
- Installation ease: Some solutions require minimal installation (heating buckets or covers) while others pair with existing troughs for a complete system.
- Maintenance considerations: Cleanliness, ease of draining, and accessibility influence long-term reliability and animal health.
- Cost of ownership: Factor in initial cost, electricity for heaters, and potential replacements or repairs over time.
When selecting an insulated water trough solution for horses, aim for a balance of reliable ice prevention, simplicity of use, and durability to support consistent access to clean drinking water. Each option above offers distinct advantages depending on your herd size, climate, and barn setup.
