You can keep your horse hydrated all winter long by using the Allied Precision Bucket Heater to combat winter ice and chilly water. This heater, in contrast to other de-icers, is made to heat water instead of de-ice it.
Depending on the amount of water present and the insulation of the container, this heater will continue to heat constantly past 150 degrees and toward boiling. Each unit includes a stainless steel guard and an automatic shutoff so you may place it in the bucket and return at a later time.
