Beef Cattle Water Trough Heating: Options for Winter

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

• Maintaining adequate water intake (8-20 gallons/head/day) is critical for beef cattle performance and health in winter; reduced intake leads to decreased feed consumption, weight loss, and increased risk of digestive issues like constipation and impaction.
• Electric immersion heaters are the most cost-effective for initial installation but require electricity at the trough and do not protect the water supply line from freezing, necessitating insulation of all exposed pipes.
• Heated automatic waterers offer superior reliability and labor savings by keeping the entire water system ice-free, though they incur higher upfront costs and require buried water and electrical lines.
• Tank deicers provide a portable, less expensive solution for keeping a portion of a trough open, but are less efficient than insulated waterers and do not safeguard the water supply line.
• Propane heaters are viable for remote locations without electricity but present higher operating costs, fuel management needs, and potential fire/carbon monoxide hazards requiring strict safety protocols.
• Geothermal systems offer the lowest long-term operating costs and highest reliability due to utilizing the earth's stable temperature, but demand the most significant initial investment and are best suited for permanent installations.

Keeping water available to beef cattle through freezing weather is one of the most demanding chores on a cow-calf operation. When temperatures drop below 32 degrees Fahrenheit, a reliable water supply becomes a matter of animal performance, health, and daily labor. This article compares the main systems for heating a cattle water trough, explains how each option works, and gives practical guidance for choosing, installing, and maintaining winter watering equipment. It is written for beef producers who manage cow-calf herds, backgrounding operations, or feedlots in cold climates and need a dependable way to keep cattle drinking through the winter.

At a Glance

• Cattle need 8 to 20 gallons of water per head per day in winter depending on size, diet, and weather.
• Decreased water intake leads to lower feed intake, reduced weight gain, and increased risk of digestive problems.
• The main trough heating options are electric immersion heaters, heated automatic waterers, tank deicers, and propane or geothermal systems.
• Electric immersion heaters are the most common and least expensive to install but require electricity at the water source.
• Heated automatic waterers cost more upfront but eliminate daily breaking and cleaning of ice.
• Tank deicers are simple and portable but less efficient than insulated heated waterers.
• Propane heaters work where electricity is not available but require ventilation and regular fuel checks.
• Geothermal systems have the highest installation cost but the lowest operating cost over time.
• Choose heater wattage based on tank size, exposure, and expected low temperatures.
• Check water flow daily even with a heater installed. A frozen supply line or stuck float can shut down water delivery.
• Insulate supply lines and place heaters where they protect the water inlet, not just the surface.

Why Winter Water Intake Matters for Beef Cattle

Cattle are large animals that require significant water even in cold weather. A 1,300 pound cow in mid-gestation needs about 8 to 12 gallons per day. A lactating cow needs 15 to 20 gallons or more. Feedlot steers on a high grain diet drink 10 to 16 gallons daily. When water consumption drops, feed intake drops within 24 hours. This causes weight loss, reduced milk production, and poorer body condition going into calving season.

Cold water itself is not harmful to cattle. Cattle can drink water at near freezing temperatures without becoming sick. The problem is when water is not available at all because the trough is frozen solid. Cattle will eat snow to meet some of their water needs, but snow consumption is rarely enough for high producing animals. A cow eating snow uses body energy to melt it, which increases her energy requirement at the exact time she needs to conserve condition. Research from the Beef Cattle Research Council notes that cattle can use snow as a water source in some conditions, but this practice is not recommended for lactating cows or during extreme cold.

Dehydration in winter shows up as reduced feed intake, firm feces, and decreased urine output. In severe cases, cattle become constipated and may show signs of impaction. Cows that are close to calving are especially at risk because dehydration can lead to calving difficulty and poor colostrum quality. A reliable heated water source prevents these problems and keeps cattle performing at their genetic potential through the winter months.

Understanding the Freezing Problem

Water troughs freeze from the surface down. Ice forms first on top and gradually thickens as cold air removes heat from the water. A 2 inch layer of ice stops cattle from drinking. Thicker ice can damage the trough itself when it expands and pushes against the sides.

Several factors determine how fast a trough freezes:

• Air temperature and wind speed. Wind removes heat from the water surface much faster than still air.
• Trough size and surface area. A wide shallow trough loses heat faster than a narrow deep one because more surface is exposed.
• Trough material. Metal conducts heat away quickly. Rubber and plastic insulate better but still freeze in extreme cold.
• Water flow. A trough that receives continuous fresh water from a well or spring stays ice free longer because groundwater enters at about 50 degrees Fahrenheit.
• Sun exposure. Troughs in full shade freeze faster and stay frozen longer than those in direct sun.

The goal of any heating system is to replace the heat lost to the air faster than the water can freeze. The amount of heat needed depends on the trough size, the temperature difference between water and air, and the wind exposure. A small 30 gallon tank in a sheltered barn might need only a 200 watt heater. A large 200 gallon metal tank exposed to a north wind might need 1,500 watts or more.

Electric Immersion Heaters

Electric immersion heaters are the most widely used option for heating beef cattle water troughs. These devices sit directly in the water and use electric resistance elements to transfer heat into the water. They are relatively inexpensive, easy to install, and available at most farm supply stores.

How Immersion Heaters Work

An immersion heater consists of a heating element enclosed in a waterproof housing. The element is connected to a power cord that plugs into a grounded electrical outlet. When plugged in, the element heats up and transfers heat to the surrounding water. Most units have a built-in thermostat that cycles the heater on and off to maintain a target water temperature, usually between 40 and 50 degrees Fahrenheit.

There are two main styles of immersion heaters for livestock water:

• Drop-in heaters. These hang over the edge of the trough with the heating element submerged. They are portable and can be moved from tank to tank.
• Submersible heaters. These sit on the bottom of the trough and are fully covered by water. They are more stable than drop-in units but require the trough to be at least partially full to operate safely.

Sizing an Immersion Heater

Selecting the right wattage is the most important decision when buying an immersion heater. Too little wattage will not keep the water ice free in extreme cold. Too much wattage wastes electricity and can make the water uncomfortably warm, which encourages algae growth.

Use these general guidelines for sizing:

• 250 to 500 watts for a small trough up to 50 gallons in mild winter areas
• 500 to 1,000 watts for a 50 to 150 gallon trough in moderate winter areas
• 1,000 to 1,500 watts for a 150 to 300 gallon trough in cold winter areas
• 1,500 watts or more for large troughs over 300 gallons or troughs in extreme northern climates

These are starting points. A trough in a windy exposed location needs more wattage than the same trough in a sheltered barn. A metal trough loses heat faster than a plastic one. If you are unsure, choose a higher wattage unit with a thermostat. The thermostat will cycle the heater off when the water reaches temperature, so the higher wattage does not necessarily mean higher electricity use.

Installation Tips

Follow these steps to install an immersion heater safely:

1. Read the manufacturer instructions completely before installation.
2. Place the heater in the trough before filling it with water. Never plug in a heater that is not fully submerged.
3. Position the heater near the water inlet so incoming water circulates past the element.
4. Run the power cord over the top edge of the trough and secure it so cattle cannot chew or pull on it.
5. Plug the heater into a ground fault circuit interrupter outlet. This is essential for safety when using electricity near water.
6. Use a heavy duty extension cord rated for outdoor use if the outlet is far from the trough. Keep the cord connection off the ground and protected from moisture.
7. Check the heater daily during extreme cold to confirm the element is working.

Safety Considerations

Electricity and water are a dangerous combination. Every immersion heater installation must include a ground fault circuit interrupter outlet. This device shuts off power instantly if it detects a short circuit. Test the ground fault circuit interrupter monthly by pressing the test button.

Inspect the power cord regularly for cracks, chew marks, or frayed insulation. Cattle are curious and will investigate a new cord in their water tank. Run cords through metal conduit or PVC pipe where they are within reach of cattle. Hang the cord connection point above the trough so water cannot run down the cord into the outlet.

Never use a household extension cord rated for indoor use. Outdoor cords have thicker insulation and are designed to handle moisture and temperature extremes. Use the shortest cord that reaches the outlet to reduce voltage drop and tripping hazards.

Advantages of Immersion Heaters

Immersion heaters are the cheapest heating option to purchase. A basic 500 watt unit costs less than a tank of feed. They work with existing troughs, so there is no need to replace the water system. They are portable, which makes them useful for temporary setups or for moving between pens. When one heater fails, a replacement is available at most farm stores the same day.

Disadvantages of Immersion Heaters

The main drawback is that immersion heaters do not prevent the water inlet from freezing. If the supply line or float valve freezes, the trough runs dry even though the heater is working. You must insulate and protect the entire water delivery system, not just the water in the tank.

Immersion heaters also leave the water surface partially open. In extreme cold, ice can form around the edges of the trough even when the center is open. Cattle may not break through this ring of ice to reach the water. Some producers use a floating tank heater that keeps a circle of open water, but these are less effective than a fully heated waterer.

Electricity use is another consideration. A 1,000 watt heater running continuously uses 24 kilowatt hours per day. At 15 cents per kilowatt hour, that is $3.60 per day, or over $100 per month for a single trough. Thermostatically controlled units run less than continuously, but winter electricity bills still rise noticeably.

Heated Automatic Waterers

Heated automatic waterers are the premium solution for winter beef cattle watering. These are insulated units that combine a water storage area, a heating element, and a float valve in one package. They are designed to keep water ice free without the need for daily management.

How Heated Waterers Work

A heated automatic waterer is essentially a small insulated tank with one or more drinking openings. Water enters through a float valve that maintains a constant level. A heating element, usually 300 to 900 watts, keeps the water above freezing. The entire unit is insulated with foam or fiberglass to minimize heat loss.

Cattle drink by pushing a paddle or by drinking from an open access point. Some models have a ball or flap that covers the water surface when cattle are not drinking. This reduces heat loss and keeps the water cleaner.

Heated waterers come in two main configurations:

• Single drinker models for one animal at a time
• Double drinker models with access from two or more sides

Installation Requirements

Heated waterers require a buried water line and an electrical supply. The water line must be installed below the frost line to prevent freezing between the well and the waterer. The electrical line can be buried or run overhead, but it must be protected and grounded.

Installation steps:

1. Choose a location that is accessible to cattle and to your tractor or truck for service.
2. Dig a trench from the water source to the waterer location. The trench must be below the frost depth for your area.
3. Lay the water supply line in the trench. Use a line that is rated for underground burial.
4. Install a shutoff valve and drain valve at the waterer end so you can winterize the system.
5. Set the waterer on a compacted gravel base. The base should be slightly above ground level to prevent mud from accumulating around the unit.
6. Connect the water line to the waterer inlet.
7. Run electrical power to the waterer. Use a ground fault circuit interrupter outlet or a direct wired connection.
8. Fill the waterer and check for leaks.
9. Plug in the heater and verify that it operates.

Choosing a Heated Waterer

Consider these factors when selecting a heated automatic waterer:

• Capacity. A waterer that holds 10 to 20 gallons is enough for a small herd. Larger herds need units that recover quickly or have higher storage capacity.
• Insulation quality. Look for units with thick foam insulation and tight fitting covers.
• Material. Polyethylene and stainless steel are common. Polyethylene is lighter and resists corrosion. Stainless steel is more durable but more expensive.
• Energy efficiency. Some models are rated by the manufacturer for energy use per month. Compare these ratings when choosing between brands.
• Access for cleaning. The unit should have a drain plug and an opening large enough to scrub the interior.

Advantages of Heated Waterers

Heated waterers are the most reliable winter watering option. They keep the entire water supply ice free, including the float valve mechanism. Cattle always have access to water without you breaking ice. The insulation reduces electricity use compared to open troughs with immersion heaters. A well installed heated waterer can cut winter water heating costs by 50 percent or more compared to an uninsulated tank.

These units also keep water cleaner. The covered design prevents leaves, dirt, and manure from blowing into the water. Cleaner water means fewer disease problems and less frequent cleaning.

Disadvantages of Heated Waterers

The upfront cost is the biggest barrier. A quality heated automatic waterer costs several hundred to over a thousand dollars. Installation adds the cost of trenching, water line, and electrical work. If you are replacing an existing watering system, you must also remove the old trough and run new lines.

Heated waterers require electricity. A power outage during a cold snap means frozen water within hours. Producers in remote areas or areas with unreliable power should have a backup plan, such as a generator or a spare immersion heater for a backup tank.

Some cattle take time to learn how to use a new waterer, especially models with paddle or flap openings. Most cattle figure it out within a day or two, but you may need to show them by pushing the paddle yourself.

Tank Deicers

Tank deicers are a middle ground between simple immersion heaters and full heated waterers. These are floating or submersible devices that keep a small area of open water in a larger trough. They are less expensive than heated waterers and easier to install than a full plumbing project.

Types of Tank Deicers

• Floating deicers. These sit on the water surface and keep a circular area ice free. They are powered by electricity and have a built-in thermostat.
• Submersible deicers. These hang in the water from the trough edge and heat the surrounding water. They are similar to immersion heaters but often have better thermostats.
• Solar deicers. These use solar panels to power a small heating element. They work well in sunny areas but provide limited heat on cloudy days or at night.

Using a Tank Deicer Effectively

A deicer is only effective if it is sized correctly for the trough. A small deicer in a large tank will keep only a small circle open. Cattle may not be able to reach that circle if ice surrounds it.

Position the deicer near the water inlet so the incoming water keeps the area around the deicer from freezing. Place the deicer where cattle can reach the open water easily. In a long trough, you may need two deicers to provide adequate access.

Use a deicer with a thermostat so it only runs when the water temperature approaches freezing. This saves electricity during milder weather.

Advantages of Tank Deicers

Tank deicers are inexpensive and portable. They work with existing troughs, so there is no need to install new plumbing. They are simple to understand and replace. For a producer with a few small troughs, deicers are a practical and affordable solution.

Disadvantages of Tank Deicers

Deicers do not protect the water supply line or float valve. If the line freezes, the trough goes dry even with a working deicer. Deicers are also less energy efficient than insulated waterers because they heat a large open surface. In extreme cold, a deicer may not keep up with heat loss from a large tank.

Solar deicers are limited by weather. They provide little heat on overcast days and no heat at night. They are best suited to mild winter areas or as a supplement to other heating methods.

Propane Heaters

Propane powered water tank heaters are an option for locations without electricity. These units burn propane to heat water in a trough. They are less common than electric systems but serve an important niche for remote pastures and off-grid operations.

How Propane Heaters Work

A propane tank heater consists of a burner unit that sits below or beside the water trough. The burner heats a transfer plate or a heat exchanger that contacts the water. A thermostat controls the gas flow to maintain water temperature. Some units use a thermocouple to shut off the gas if the flame goes out.

Propane heaters require a propane supply. A 100 pound tank lasts several days to a few weeks depending on the heater size and weather. You must check the tank level regularly and have a spare tank ready for refills.

Installation and Safety

Propane heaters must be installed according to the manufacturer instructions and local codes. Key safety points:

• Place the heater on a level, non combustible surface.
• Keep the propane tank at least 10 feet from the heater.
• Use a regulator designed for the heater model.
• Check all connections for leaks before lighting.
• Ensure adequate ventilation. A propane heater in an enclosed barn can produce carbon monoxide.
• Install a carbon monoxide detector if the heater is in a building.

Advantages of Propane Heaters

Propane heaters work where electricity is not available. They are useful for winter grazing operations in remote areas. They can be moved between locations more easily than a buried electric system. Propane is a reliable fuel that stores well in cold weather.

Disadvantages of Propane Heaters

Propane is more expensive than electricity for the same amount of heat. You must monitor fuel levels and arrange deliveries. Open flame near livestock is a fire hazard, especially around hay or bedding. Propane heaters require more maintenance than electric systems, including cleaning burners and checking thermocouples.

Geothermal and Ground Source Systems

Geothermal watering systems use the earth's constant temperature to keep water from freezing. These systems are the most expensive to install but have the lowest operating cost over time.

How Geothermal Waterers Work

A geothermal waterer consists of a storage tank buried below the frost line. The tank holds 50 to several hundred gallons of water. A float valve fills the tank from a well or spring. A drinking bowl or access point extends above ground. The surrounding earth keeps the buried water above freezing, and the above ground portion is insulated to prevent heat loss.

Some geothermal waterers use a circulation pump to move water from the buried tank to the drinking bowl. Others use a simple float system where cattle drink directly from the buried tank through a riser pipe.

Installation Considerations

Installing a geothermal waterer requires significant excavation. You must dig a hole deep enough to place the tank below the frost line, which can be 4 to 6 feet in northern areas. The water supply line must also be buried below the frost line.

The drinking bowl must be insulated and heated or designed so that water drains back into the buried tank when cattle stop drinking. Some models use a small electric heater in the bowl to prevent freezing at the surface.

Advantages of Geothermal Systems

Once installed, geothermal waterers cost almost nothing to operate. There is no electric bill for heating and no propane to buy. The buried tank holds a large volume of water, so the system provides water even during power outages. Geothermal waterers are reliable and require minimal maintenance.

Disadvantages of Geothermal Systems

The installation cost is the highest of any option. Digging, tank purchase, and plumbing can cost several thousand dollars. The system is fixed in place and cannot be moved easily. If the buried tank develops a leak, repair is difficult and expensive. Geothermal systems work best for permanent watering sites that serve the same pasture for many years.

Comparing the Options

The table below summarizes the main differences between the heating options.

Choose a system based on your specific situation. A producer with a single trough next to an existing outlet may find an immersion heater perfectly adequate. A larger operation with multiple watering sites may save money and labor with heated automatic waterers. A remote pasture with no power may need a propane heater or a geothermal system.

Step by Step Guide to Winterizing Your Water System

No matter which heating option you choose, the entire water delivery system must be protected from freezing. Follow these steps to prepare your watering system for winter.

Step 1: Inspect All Components

In late fall, walk through every pasture and check each watering site. Look for:

• Leaks in troughs, pipes, and fittings
• Damaged float valves
• Worn or cracked heater cords
• Missing insulation on exposed pipes
• Mud or manure buildup around troughs

Repair any problems before the first hard freeze. A small leak that goes unnoticed in October becomes a frozen pipe in January.

Step 2: Clean and Drain Troughs

Drain each trough and scrub the interior to remove algae, sludge, and manure. Rinse thoroughly and refill with clean water. A clean trough is easier to keep ice free because sediment and organic matter trap heat and reduce heater efficiency.

Step 3: Insulate Exposed Pipes

Wrap all exposed water lines with foam pipe insulation. Pay special attention to riser pipes, valves, and connections above ground. Use heat tape on pipes that are prone to freezing, but follow the manufacturer instructions carefully. Heat tape must be applied evenly and covered with insulation to work properly.

Step 4: Install or Test Heaters

Install new heaters or test existing ones before the cold weather arrives. Plug in each heater and verify that it warms up. Check thermostats by placing a thermometer in the water. Confirm that ground fault circuit interrupter outlets are working.

Step 5: Position Heaters Correctly

Place heaters near the water inlet and away from the edges where cattle drink. A heater in the center of a large trough keeps the entire volume warmer than a heater at one end. Make sure the heater cannot be pushed out of position by cattle.

Step 6: Protect Cords and Connections

Route power cords where cattle cannot reach them. Use conduit or PVC pipe to protect cords on the ground. Elevate connections above the trough rim so water does not run down the cord. Secure cords to posts or trough stands with zip ties.

Step 7: Test the System in Cold Weather

When the first cold snap arrives, check each watering site daily for the first week. Confirm that water is flowing, the heater is working, and cattle are drinking. Make adjustments as needed.

Step 8: Monitor Throughout the Winter

Check water flow and heater operation at least once per day during freezing weather. Carry a hammer or axe to break ice in case a heater fails. Keep spare heaters, cords, and thermostats on hand for quick replacement.

Common Mistakes to Avoid

Undersizing the Heater

Many producers buy the cheapest heater on the shelf without considering their trough size and local climate. A 250 watt heater cannot keep a 200 gallon metal tank ice free in a North Dakota winter. Match the heater wattage to the trough and the expected low temperatures.

Ignoring the Water Supply Line

A heater in the trough does nothing if the supply line is frozen. Insulate all exposed pipes and bury lines below the frost line. Install a shutoff and drain valve so you can empty the system if needed.

Using Unsafe Electrical Setup

Plugging a water heater into an ungrounded outlet or a regular extension cord is a fire hazard. Use only ground fault circuit interrupter outlets and outdoor rated cords. Inspect cords regularly for damage.

Forgetting to Check Water Daily

A heater can fail at any time. A power outage, a tripped breaker, or a burned out element can leave cattle without water within hours. Check each watering site daily, even when everything seems fine.

Not Having a Backup Plan

Every watering system can fail. Keep a spare heater, a backup tank, or a generator on hand. Know how to provide water quickly if your primary system goes down.

Letting Ice Build Up Around the Trough

Ice around the outside of a trough pushes against the walls and can crack or split the tank. Break up ice buildup regularly. Place the trough on a gravel base to improve drainage and reduce ice accumulation.

Waiting Until the Last Minute

Winterizing a water system takes time. Do not wait until the first snowstorm to inspect heaters, insulate pipes, and test outlets. Prepare in October or early November, before the hard freezes arrive.

Decision Thresholds: When to Upgrade Your System

If you are managing your current system but thinking about upgrading, use these thresholds to guide your decision.

When to Replace an Immersion Heater

Replace an immersion heater if:

• The cord is cracked, frayed, or shows signs of chewing
• The thermostat no longer cycles the unit off
• The heating element shows signs of corrosion or pitting
• The unit is more than 5 years old and you are not sure of its condition

When to Move from Immersion Heaters to Heated Waterers

Consider upgrading to a heated automatic waterer if:

• You are breaking ice daily despite having a heater
• Your electricity bill for water heating is consistently over $50 per month per trough
• You are replacing a trough anyway due to damage
• You are tired of daily water checks and want a more reliable system
• You have multiple troughs and want to reduce total labor

When to Consider a Geothermal System

A geothermal system makes sense if:

• You are establishing a new permanent watering site
• You have reliable electricity but want to eliminate operating costs
• You have a site that will be used for many years
• You can absorb the high upfront cost

When to Add a Backup System

Add a backup water source if:

• Your area experiences frequent power outages in winter
• Your water system has failed more than once in the past two winters
• You have cattle that cannot go without water for more than a day
• You are calving in winter and need guaranteed water for lactating cows

Monitoring and Recordkeeping

Keeping records of your winter watering system helps you identify problems early and plan for upgrades.

Daily Checks

Each day during freezing weather, record:

• Water temperature in each trough
• Heater operation status
• Water flow rate
• Any ice formation
• Number of cattle drinking

A simple log sheet posted near each watering site works well. Note any problems and what you did to fix them.

Weekly Checks

Once per week, inspect:

• Heater cords for damage
• Thermostat operation
• Float valve function
• Trough condition for cracks or leaks
• Insulation condition on pipes

Seasonal Records

At the end of winter, record:

• Total electricity or propane cost for water heating
• Number of heater failures
• Number of times you had to break ice
• Any water related health problems in the herd

Use these records to compare systems and decide whether to upgrade before next winter.

Health Problems Related to Winter Water

Dehydration is the most common water related health problem in winter beef cattle. Signs include:

• Reduced feed intake
• Firm, dry feces
• Decreased urination
• Lethargy
• Poor body condition

Cattle that are dehydrated for several days may develop impaction, a blockage in the digestive tract. This is a serious condition that requires veterinary treatment. If you notice cattle not drinking and showing signs of dehydration, check the water system immediately.

Dirty water can cause other problems. Troughs that are not cleaned regularly can harbor bacteria and algae. Cattle may refuse to drink foul water, leading to dehydration even when water is present. Clean troughs at least monthly, more often in warm weather.

Very cold water can reduce feed efficiency. Cattle that drink ice water use body energy to warm the water to body temperature. A cow drinking 10 gallons of 35 degree water uses about 1,000 calories to warm it to 101 degrees. This energy could otherwise go toward weight gain or milk production. Heated water at 45 to 50 degrees reduces this energy loss.

When to Call a Veterinarian or Extension Agent

Most winter watering problems are mechanical and can be solved with basic troubleshooting. However, contact a veterinarian if:

• Cattle show signs of dehydration that do not improve after water is restored
• Multiple animals are off feed or showing signs of impaction
• Cattle are drinking excessively or showing unusual water related behavior
• You suspect water quality issues such as nitrates, sulfates, or bacterial contamination

Contact your local extension agent if:

• You are planning a new watering system and want advice on sizing or installation
• You are considering a geothermal system and need information on frost depth in your area
• You have questions about water quality testing
• You want to compare costs of different heating options for your operation

Extension agents have access to regional data on frost depth, electricity rates, and recommended equipment. They can also connect you with other producers who have experience with different systems.

Frequently Asked Questions

How much water do beef cattle need in winter?

A dry cow needs 8 to 12 gallons per day in winter. A lactating cow needs 15 to 20 gallons or more. Feedlot cattle on high grain diets need 10 to 16 gallons daily. These amounts increase during extreme cold because cattle drink more when feed intake increases to maintain body heat.

Can cattle get enough water from eating snow?

Cattle can survive on snow for short periods, but snow is not a reliable water source for producing animals. Eating snow requires body energy to melt, which increases energy needs. Lactating cows and cattle in poor condition should always have access to liquid water.

What size heater do I need for my cattle trough?

Match the heater wattage to the trough size, exposure, and expected low temperatures. A 250 to 500 watt heater works for a small trough up to 50 gallons in mild areas. A 1,000 to 1,500 watt heater is needed for large troughs in cold climates. When in doubt, choose a higher wattage unit with a thermostat.

How much does it cost to run a heated water trough?

A 1,000 watt heater running continuously uses 24 kilowatt hours per day. At 15 cents per kilowatt hour, that is $3.60 per day. Thermostatically controlled heaters run less than continuously, reducing the cost. Heated automatic waterers are more energy efficient than open troughs because insulation reduces heat loss.

Will a heater keep my water trough from freezing in extreme cold?

A properly sized heater will keep water ice free in most conditions. The heater must be matched to the trough size and the expected low temperature. In extreme cold, even a good heater may leave some ice around the edges of a large open trough. Insulating the trough and protecting it from wind improves heater performance.

How often should I clean my cattle water trough in winter?

Clean troughs at least once per month in winter. Algae and sediment build up more slowly in cold water, but they still accumulate. A trough that is dirty may discourage cattle from drinking. Drain the trough, scrub the interior, and rinse before refilling.

What do I do if my water trough heater stops working?

Check the power source first. Is the outlet working? Has the ground fault circuit interrupter tripped? Is the cord damaged? If the power is fine, the heater element may be burned out. Replace the heater with a spare. In the meantime, break ice and provide water by other means.

Can I use a stock tank heater in a plastic trough?

Yes, most stock tank heaters work in plastic troughs. Follow the manufacturer instructions for minimum water depth and heater placement. Some heaters are designed specifically for plastic tanks. Check that the heater does not melt the plastic by keeping it away from the tank walls.
