Farm Innovators 2 Pack Submergible Tank De-Icer

The Farm Innovators 2 Pack Submergible Tank De-Icer is designed to rest at the bottom of livestock tanks, keeping water from freezing without disturbing animals. It uses a thermostatic 1000-watt heater that runs only when needed, helping to reduce electricity use. This option is best for larger livestock operations that require reliable, bottom-anchored de-icers and want a spare unit for redundancy. Caution: ensure the unit remains fully submerged and clear of debris to maintain efficient heating.

It can be used as a floating unit or submerged, and includes a full protective cage plus a cord clip for secure placement. It’s best for operators who want flexibility in tank type and straightforward installation. Limitation: the higher-wattage models consume more energy, so choose the wattage based on tank size and local climate.
Farm Innovators Submergible Bucket Heater

This 1000W submergible bucket heater is designed for up to 5 gallons, making it ideal for calves, pets, or small farm buckets. Its thermostatic control activates only when needed, saving energy and reducing waste. A low-profile form sits at the bottom of the bucket without being easily knocked loose by animals. Best for small, portable setups or remote water sources. Caution: ensure compatibility with bucket material to avoid deformation or overheating in extreme cold.

Cast aluminum construction enhances heating efficiency and durability, with a thermostat that turns on only as needed. This model suits operators seeking a flexible setup for varied tank shapes and sizes. Limitation: higher wattage means greater energy use if operated continuously in very cold regions.
Farm Innovators UPH-15 Universal Heater

The UPH-15 is a universal drain plug de-icer designed for all plastic or metal stock tanks. Its thermostatic control helps save energy by operating only when needed. Installation is described as simple and quick, making it a practical option for busy farm routines. Choose this if you want a universal fit with minimal setup across multiple tank types. Caution: ensure drain plug access is available on your tanks for proper mounting.
Buying Guide: Key Considerations
What tank type do you have? Submersible de-icers work well in plastic, rubber, and metal tanks, while drain-plug designs fit Rubbermaid-style reservoirs. Consider tank size and livestock density to select the appropriate wattage. Thermostatic control helps conserve energy by heating only when necessary. Durability features, such as chew-proof cords and protective cages, prolong life in farm environments. If you switch between tanks, a versatile unit that can operate as either floating or submersible offers flexibility. For remote locations, consider models with longer cords or easier installation.
