When it comes to winter, water troughs freezing over is a real problem. Fortunately, there are some great water trough heaters for horses and livestock that will save you the hassle of breaking ice.

Water trough heaters are heating units that are designed to safely prevent ice from forming on troughs and buckets. It is vital to keep troughs from freezing over, as horses and livestock should always have access to freshwater.

There are different types of trough heaters such as floating, submersible, bucket, solar and integrated.

Types of Water Trough Heaters

  • Floating Heaters: Floating heaters float at the top of the water and are safe to use with plastic or poly troughs. You should always plug the de-icer into a GFI outlet. Though they are a great option, some curious horses may play with them.
  • Submersible Heaters: Submersible heaters lie at the bottom of the trough, keeping it out of the way. Most submersible heaters include a wire guard so they are safe to work in metal and plastic tanks.
  • Bucket Heaters: Bucket heaters are specifically designed for buckets and not full-size water troughs.
  • Integrated Heaters: Integrated heaters are convenient to use, as you can simply use a switch to turn the heat on and off for the trough. However, they often require a professional to set up the water lines, electricity and concrete.
  • Solar Heaters: Solar trough heaters use the sun for power, meaning you won’t have to mess with cords or wires. They can be used with automatic waterers, manual troughs or even tied to your water line.

If you live in a particularly cold climate, having a water trough heater can be a lifesaver. Not only does breaking ice on buckets take time, but it can also be difficult as you have to do it several times a day sometimes.

Here are the best water trough heaters for livestock and horses.

6 Ways to Keep a Water Trough From Freezing

Though water heaters and heated troughs are a great way to keep tanks freezing over in winter, they are not a practical option for everyone. Fortunately, there are some other ways to keep water troughs from forming ice.

1. Place Your Trough in Direct Sunlight

Place your trough in a place where it will receive direct sunlight. Placing your trough in a south-facing area will increase the amount of sunlight it will get.

Though the sunlight doesn’t guarantee to keep ice away in frigid temperatures, it can certainly help. This is a great option if you live in an area that doesn’t get much below freezing during wintertime.

2. Insulate Your Trough

Insulation is an easy and effective way to prevent ice from forming over water tanks. Wrapping styrofoam and foil-covered insulation around your trough help prevent it from freezing over.

In addition, placing your trough in a larger trough and filling the space in between with insulation is an even more effective way to prevent ice. Alternatively, you can also use a plywood box and place your trough inside, filling the space in between with insulation.

3. Bury Your Trough

Though this can be labor-intensive, burying your trough provides protection from ice. The ground can work as an installation to prevent the water from freezing over.

This option is not practical for everyone and is best done before winter begins. However, if the ground is already too hard, a shallow hole filled with straw can also work.

4. Use a Float

Many people swear by using floats as an alternative to water heaters. A floating object will bob about, moving the water and making it less likely for ice to develop.

A soccer ball or a 2-liter soda bottle partially filled with a mix of water and salt can effectively work as a float. However, some curious horses will play with floating objects and remove them from the water.

5. Try a Constant Flow Waterer

Constant flow waterers are another alternative to trough water heaters. They supply a small, constant stream of flowing water that helps prevent ice from forming.

Even just a small amount of water works to break the surface tension. By plumbing a pipe to carry any overflow through a buried PVC perforated pipe, you don’t have to worry about spillage.

6. Water Trough Heater

As you have already seen above, a water trough heater is probably the best way to keep water in a trough from freezing. However, they are not as practical as other solutions.

Are Water Trough Heaters Safe for Horses?

Water trough heaters are safe for horses and cattle if they are properly used. However, it is vital you thoroughly read the instructions and use all safety precautions when using them.

Make sure to plug your heaters into a GFCI (ground-fault circuit interrupter) outlet. Always be certain the cords are not in the way and your animals don’t chew on them. Regularly inspect your heaters to ensure they are running properly.

What Wattage Do You Need to Heat a Trough?

For troughs 50 gallons and under, it is recommended to use 250 watts and for troughs, 70 gallons and under, 500 watts is recommended. For troughs that are 70-100 gallons, use 1,000 watts and for 100-300 gallons, use 1,500 watts.

Wattage measures the amount of electrical flow to the unit. For trough heaters, the higher the wattage, the more efficient it is at heating the water. In addition, the higher the wattage, the faster it will heat your water.
