K&H has redefined the stock tank de-icer market with the new Ultimate Stock Tank De-Icer. This revolutionary de-icer can be floated or submerged to keep stock tank water open. It's available in 250, 500, 750, 1000, and 1500 models, allowing livestock owners to use only the wattage needed by following our convenient Zone Chart.

Float or Submerge

Now you can float or submerge your stock tank de-icer without purchasing two separate units. To use it as a floating de-icer, leave the float ring attached. To use it as a submersed de-icer, simply unscrew and remove the float ring. This simple process requires only a few seconds and allows consumers to change the functionality of their de-icers at any time.

Thermostatic Temperature Control

Internal thermostats automatically monitor water temperature and turn the unit on and off to keep the average water temperature just above freezing. Our unique technology ensures that your stock tank de-icer will only run as often as needed. In fact, it's thermostatically controlled to never get hot when properly submerged in water.


This product has been tested and certified by MET Labs to meet their high standards for electrical product safety.

As with any electrical product used in wet locations, please plug the Ultimate Stock Tank De-Icer into a ground fault circuit interrupter (GFCI) outlet.

Cord Clip Included

A free cord safety clip is also included with every de‐icer. This ingenious clip secures the de‐icer to the edge of the stock tank, bucket or container to help prevent chewing, cribbing or removal of the de‐icer from the tank.

Determining the Wattage You Need

With the K&H Ultimate Stock Tank De-Icer you have the freedom to select the proper wattage for your needs. Choose from 250, 500, 750, 1000, and 1500 watt models.

Please consult our zone chart below to determine the wattage needed for your climate and application. (Click image to make it larger.)

Product Q&A

Product-Specific Questions

How do I determine which wattage model I need?

To determine the proper wattage for your tank size and climate, please consult our Zone Chart.

What happens if I use a higher wattage deicer than needed in my stock tank?

The deicers are thermostatically controlled. This means, as long as you purchased the minimum wattage required for your zone and tank size, they will work fine.

Keep in mind that higher wattage models will use more electricity than the lower wattage models. For example, the 750 watt deicer will use three times the amount of electricity when running versus the 250 watt deicer.

There is a piece of Styrofoam in the ring. Do I leave it in?

The styrofoam is part of the float ring. To use this product as a floating de-icer, leave the float ring attached. To use it as a submersed de-icer, simply unscrew and remove the float ring.

Does this heater turn itself off and on with the ambient temperature? Or, should we consider also purchasing a plug with a thermostat?

You do not need to purchase a plug with a thermostat. Our Ultimate Stock Tank De-Icer units are thermostatically controlled to keep the average water temperature just above freezing. They feature internal thermostats and will turn on and off as necessary to prevent the tank water from freezing.

Can I used multiple de-icers for a large stock tank?

Yes, you can use multiple de-icers. As long as you spread them out away from each other to provide even coverage, this solution should work.

General Questions about Outdoor Heated Products

How long is the cord?

The cord is 5.5 feet long.

Can I use an extension cord with this product?

MET requires that all manufacturers put the extension cord statement “Do not use with extension cord” on every item that is MET listed by UL 499 standards. This is because they cannot test every extension cord on the market in conjunction with our products for safety. Also, MET suggests that an extension cord is not recommended as a permanent fixture and should only be a temporary solution when using any electrical product.

Temporary use of a UL listed cord is fine, but consult your electrician for the proper cord for your application. For more information on MET safety testing, please visit their website at www.metlabs.com.

How long can a heated product be plugged in?

MET Safety Laboratories suggests unplugging the product if you leave your home on an extended vacation, as they do with any electrical appliance. Otherwise, it is designed for 24/7 operation and you can leave it plugged in all day. This item has been certified by MET labs to adhere to strict electrical safety standards. For more information, please visit www.metlabs.com.

Is there an off/on switch?

There is not an off/on switch. It is always on when plugged in.
