The Waterbucket Cozy has removable insulation for your standard 5-gallon water bucket and heated bucket. The Cozy provides easy, effective insulation of your horse’s water supply by wrapping around the bucket and securing with a Velcro closure, warming the bucket and dramatically reducing ice formation. If you already pay to heat your water bucket with a stock tank, the Cozy will significantly lower your electric bill, saving you valuable time and money. Two years of real world, real winter testing in freezing New Hampshire brings this product to you with a money back satisfaction guarantee
