Best Heated Water Buckets for 2026: Horse, Goat, and Barn Buckets That Keep Water Open

A heated bucket is a regular stall bucket with a heating element built into the wall or base and a thermostat that switches it on only when the water gets cold. It does not warm the water - it keeps it from freezing. Here is how the models on Amazon compare, using only what each listing states. The Farm Innovators and API websites would not load when we checked, so every number below is labeled as coming from the listing.

Heated Buckets Compared

How to Choose

Size it to the animal. In our view, a horse stall calls for the larger 4.5- and 5-gallon buckets, since they hold more between fills; the 3-gallon FB-80R's listing names horses, goats, sheep, and poultry. The listing for the 2-gallon HB-60 names dog kennels and livestock water.

Rubber or plastic. Both Farm Innovators rubber buckets are listed as rated down to -35F, and the FB-80R listing says its rubber shell flexes instead of splitting when it is dropped or kicked. The API 20FB is polyethylene, which API's listing says is impact resistant and helps prevent stress cracks.

Flat back. A flat-back bucket sits flush against a wall or stall panel so it hangs square instead of swinging, per the Farm Innovators listings. If you set buckets on the ground or hang them on a fence post, a round bucket works too.

The cord. Horses and goats chew. The FB-80R listing describes anti-chew protection on the cord, and the API 20FB listing describes a chew-proof sheathed cord. Plan where the cord runs before you hang the bucket, and follow the manual's guidance on extension cords.

The Picks

Farm Innovators FB-15R (4.5 Gallon): Our Pick for Horse Stalls

Per the listing: a 4.5-gallon rubber flat-back bucket with a 90-watt element that runs only when the thermostat calls for it, a concealed heating element, and a metal handle shaped for hanging. The rubber body is rated down to -35F without cracking. It is the most bucket for a stall on this page short of the API's extra half gallon.

Farm Innovators FB-80R (3 Gallon): The Smaller Rubber Bucket

Per the listing: 3 gallons (12 quarts), a 70-watt element with thermostat, recycled rubber rated to -35F, a steel bail handle, and volume markings inside. The listing names horses, goats, sheep, and poultry. A good second bucket in a stall or the main bucket for small ruminants.

API 20FB (5 Gallon): The Largest Bucket

Per the listing: holds and heats up to 20 quarts, a 115-watt element with thermostat and over-temperature protection, a polyethylene body, and a chew-proof sheathed cord. It is also the only bucket here whose listing says it is CSA and UL listed. Note that API's cord on this model is short - the listing gives it as 6 inches - so plan on an outlet or cord close by.

Farm Innovators HB-60 (2 Gallon): For Kennels and Small Animals

Per the listing: a 9-quart plastic bucket with a 60-watt thermostatic element that keeps water from freezing in single-digit temperatures. It is round rather than flat-back, and the listing names dog kennels and livestock water. At 9 quarts it is the smallest bucket here.

Bucket, Tank Heater, or Waterer?

A heated bucket serves one stall or pen. For a pasture trough or stock tank, a stock tank deicer is the right tool. For chickens, ducks, and other poultry, see our heated chicken waterer guide - poultry drinkers use nipples or fount bases rather than open buckets. And if the problem is frozen pipes to the barn, see heat tape for pipes.

Common Questions

How many watts is a heated water bucket?

The buckets on this page range from 60 watts (the 2-gallon Farm Innovators HB-60) to 115 watts (the 5-gallon API 20FB), per their Amazon listings. Each has a thermostat, so the element runs only when the water needs it.

Do heated buckets make the water warm?

No. They keep water from freezing rather than heating it. The thermostat switches the element on in cold weather and off again once the water is above freezing.

What size heated bucket for a horse?

For a stall, a larger bucket - 4.5 gallons like the Farm Innovators FB-15R, or 5 gallons like the API 20FB - holds more water between fills than the 2- and 3-gallon models.

How cold can a heated bucket handle?

The Farm Innovators FB-15R and FB-80R rubber buckets are listed as rated down to -35F. The HB-60 listing says it keeps water from freezing in single-digit temperatures. The API 20FB listing does not state a temperature rating.
