Broiler House Heating Systems: Types and Efficiency

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

Key Takeaways

Radiant brooders are the industry standard for broiler chick brooding due to their direct heating of birds and litter, leading to superior fuel efficiency (heating birds directly, not air volume) and enabling self-selection of comfort zones by chicks, which is critical for thermoregulation in the first weeks of life.
Forced air furnaces, while effective for rapid preheating and maintaining temperature in very cold climates, are less fuel-efficient than radiant systems and can lead to over-drying of litter, potentially causing respiratory issues and impacting feed conversion.
Accurate temperature monitoring at chick level (2-4 inches above litter) is paramount, as it can be 5-10°F cooler than at human eye level, directly influencing chick survival, feed intake, and growth rates by preventing cold stress (huddling, reduced activity) or heat stress (panting, reduced feed intake).
Proper heating system maintenance, including cleaning burners and servicing equipment before each flock, is crucial, as a dirty burner can reduce fuel efficiency by 10-20% and increase the risk of carbon monoxide production.
A robust backup plan, including secondary thermostats and alarms, is essential to mitigate risks associated with heating system failures or power outages, particularly during the critical brooding period when chicks are highly susceptible to temperature fluctuations.

Keeping broiler chicks warm is the single most important job in the first weeks of a flock's life. Chicks cannot regulate their own body temperature until they develop feathers, and even then, adult birds perform best when the house stays within a narrow temperature band. The heating system you choose affects chick survival, feed conversion, litter quality, fuel costs, and your daily workload. This guide compares the main broiler house heating systems on the market, explains how to match a system to your house size and climate, and walks through installation, management, and troubleshooting. It is written for broiler growers, farm managers, and anyone planning a new or retrofitted poultry house.

At a Glance

Radiant brooders heat birds and litter directly, not the air. They are the most fuel-efficient choice for the brooding period and are the industry standard for most broiler houses.
Forced air furnaces heat the whole house quickly and are useful for preheating and for cold climates, but they dry out litter and cost more to run than radiant systems.
Radiant tube heaters work well in houses with high ceilings and are a good option for adult birds, but they are less effective at chick level during the first week.
Space heaters and unit heaters are simple and cheap to install, but they create uneven temperatures and are best for small or temporary houses.
Fuel choice matters as much as equipment type. Propane, natural gas, electricity, and waste oil all have different costs, availability, and maintenance needs.
Measure temperature at chick level, not at human eye level. A chick feels the temperature near the litter, which can be 5 to 10 degrees F cooler than the air five feet up.
Check litter temperature and bird behavior daily. Panting chicks piled away from the heat source mean the house is too hot. Chicks huddling under the brooder mean it is too cold.
Never rely on a single thermostat. Use backup thermostats and alarms, and have a plan for a power failure during cold weather.
Clean and service heating equipment before each flock. A dirty burner can waste 10 to 20 percent of its fuel and create carbon monoxide risk.

Why Heating Is Critical in Broiler Production

Broiler chicks hatch with a body temperature around 102 to 103 degrees F, but they cannot maintain it on their own. They have a high surface area to body mass ratio, no insulating feathers, and limited energy reserves. For the first week of life, chicks depend entirely on environmental heat to stay warm. If the temperature drops below about 85 degrees F at chick level, chicks stop eating and drinking, huddle together for warmth, and may trample each other. If the temperature climbs above about 95 degrees F, chicks pant, spread out, and reduce feed intake. Either direction costs you weight gain and increases mortality.

After the first week, chicks gradually develop feathers and can handle a wider temperature range. By week three, most flocks can tolerate house temperatures in the 75 to 85 degree F range. By week six, birds do well at 65 to 75 degrees F. But even at those older ages, sudden cold stress can cause ascites, a metabolic disease that leads to fluid accumulation in the abdomen and increased death loss, especially in fast growing broiler strains.

Heating also affects litter moisture. When the house is too cold, birds huddle and produce more droppings in a small area. That wet litter releases ammonia, which damages the birds' respiratory tracts and reduces feed efficiency. A good heating system keeps litter dry by keeping birds spread evenly across the floor.

Finally, heating cost is one of the largest variable expenses in broiler production. Depending on fuel prices and climate, heating can account for 10 to 30 percent of total production cost. Choosing the right system and managing it well can save thousands of dollars per house per year.

Types of Broiler House Heating Systems

There are four main categories of heating systems used in commercial broiler houses. Each has strengths and weaknesses. Many growers use a combination, such as radiant brooders for the first two weeks and forced air for the rest of the flock.

Radiant Brooders

Radiant brooders are the most common heating system in modern broiler houses. They work by burning propane or natural gas to heat a metal canopy or ceramic plate. The hot surface radiates infrared energy downward. That energy warms the chicks, the litter, and the floor without heating the air in between. This is the same principle as standing in the sun on a cold day. The air around you is cold, but the sun's rays feel warm on your skin.

Radiant brooders come in two main designs. The first is the canopy or pancake brooder, which has a flat metal disc that glows red hot. The second is the gas-fired radiant brooder, which uses a ceramic or metal burner face that radiates heat across a wider area. Both are suspended from the ceiling on chains or cables, usually 2 to 4 feet above the litter.

Advantages of radiant brooders:

They are the most fuel efficient option for brooding because they heat the birds and litter directly instead of wasting energy on heating the whole air volume of the house.
They keep litter dry beneath the brooder, which reduces ammonia and improves foot pad health.
They create a natural temperature gradient. Chicks can move closer to the brooder if they are cold or farther away if they are warm. This lets chicks self-select their comfort zone.
They warm the floor, which is where chicks spend nearly all of their time in the first week.

Disadvantages of radiant brooders:

They do not heat the air in the house. If the house is very cold, the air may still be cool even though the litter is warm.
They are less effective at heating a house for older birds, which need warmer air rather than radiant heat at floor level.
They require careful height adjustment. If hung too high, the heat dissipates before reaching the chicks. If hung too low, chicks can overheat or the litter can dry excessively.
They can create hot spots directly beneath the brooder and cold spots between brooders if spacing is wrong.

Best use: Radiant brooders are the best choice for the first 7 to 14 days of a broiler flock. Most commercial growers use one radiant brooder per 1,000 to 1,500 chicks, spaced evenly across the brooding area.

Forced Air Furnaces

Forced air furnaces burn propane, natural gas, or fuel oil to heat air, then blow that warm air through ducts or directly into the house. They are sometimes called space heaters or unit heaters. In a typical broiler house, several furnaces are mounted along the side walls or in the ceiling, and they blow warm air across the house.

Advantages of forced air furnaces:

They heat the entire air volume of the house quickly, which is useful for preheating before chicks arrive and for maintaining temperature in very cold weather.
They provide even air temperatures throughout the house when properly sized and placed.
They can also be used to ventilate the house. Many forced air furnaces have a fresh air intake that mixes outside air with heated air, which helps control humidity and ammonia.
They are simple to operate and maintain compared to some radiant systems.

Disadvantages of forced air furnaces:

They are less fuel efficient than radiant brooders because they heat all the air in the house, not just the birds and litter.
They dry out the litter. Warm air holds more moisture, and when that air circulates, it pulls moisture from the litter. Dry litter is good, but over-drying can create dusty conditions that irritate bird respiratory systems.
They create a less natural temperature gradient. Chicks cannot move to a warmer or cooler spot as easily because the whole house is at a similar temperature.
They can create drafts if the air is blown directly at chick level.
They have more moving parts than radiant brooders, including fans, belts, and filters, which means more maintenance and more potential breakdowns.

Best use: Forced air furnaces are the best choice for preheating a house before chicks arrive, for maintaining temperature in extremely cold climates, and for heating the house during the grow-out phase when birds are older. Many growers use forced air furnaces as the primary heat source for the whole flock and radiant brooders only for the first week.

Radiant Tube Heaters

Radiant tube heaters are long metal tubes, usually 10 to 20 feet, that are heated by a gas burner at one end. The tube glows and radiates heat along its length. These are commonly used in shops, warehouses, and other large industrial buildings, and they are becoming more common in poultry houses.

Advantages of radiant tube heaters:

They provide even radiant heat over a long area, which can reduce the number of heat sources needed.
They are very fuel efficient because they heat objects and floors rather than air.
They are well suited to houses with high ceilings because they can be mounted near the ceiling and still deliver heat to the floor.
They have a long lifespan and require less maintenance than forced air furnaces.

Disadvantages of radiant tube heaters:

They are less effective at chick level during the first week because the heat is spread over a wide area. Chicks need a concentrated heat source that they can gather under.
They are more expensive to install than radiant brooders or space heaters.
They are not as effective at heating the air, so they need to be paired with a forced air system in very cold climates.
They can create uneven temperatures if the tubes are not placed correctly relative to the birds.

Best use: Radiant tube heaters are a good choice for the grow-out phase, especially in houses with high ceilings. They are also a good option for growers who want a single system that can handle both brooding and grow-out, though they may still need supplemental radiant brooders for the first week.

Space Heaters and Unit Heaters

Space heaters are small, self-contained units that burn gas or use electricity to heat a localized area. They come in many designs, including forced air, radiant, and convection models. They are most common in small or backyard broiler houses, where a single heater can handle the whole space.

Advantages of space heaters:

They are inexpensive to buy and install.
They are simple to operate and require little technical knowledge.
They are portable and can be moved between houses or areas.
They are available in many fuel options, including electricity, propane, natural gas, and kerosene.

Disadvantages of space heaters:

They create uneven temperatures. The area near the heater is warm, but the rest of the house may be cold.
They are less fuel efficient than larger systems because they do not distribute heat evenly.
They can be a fire hazard if not placed correctly or if they are too close to bedding or equipment.
They can produce carbon monoxide if not vented properly. This is a serious risk in enclosed poultry houses.
They require more frequent refueling or maintenance than larger systems.

Best use: Space heaters are best for small houses, temporary brooding areas, or emergency backup heat. They are not recommended for commercial scale broiler production because they cannot provide the even, controllable heat that a large flock needs.

Fuel Options for Poultry House Heaters

The type of fuel you use affects both operating cost and equipment choice. Consider local fuel prices, availability, and the reliability of supply before you buy a heating system.

Propane

Propane is the most common fuel for broiler house heating in the United States. It is clean burning, widely available in rural areas, and delivered by truck to on-site storage tanks. Propane is stored as a liquid under pressure and vaporizes to gas for burning.

Pros: Clean burning, low maintenance, widely available, can be stored on site in tanks of 500 to 1,000 gallons or more.

Cons: Price can fluctuate significantly with the seasons and global markets. In very cold weather, propane tanks can freeze up if they are undersized or if the vaporization rate is too low.

Management tips: Keep at least a 7 to 10 day supply of propane on hand during brooding season. Check tank gauges daily. Have a backup delivery contract with your supplier so you get priority during cold snaps.

Natural Gas

Natural gas is delivered through underground pipelines, so there is no on-site storage needed. It is often cheaper than propane on a per-BTU basis, especially in areas with abundant gas production.

Pros: No storage tanks needed, no delivery scheduling, typically lower cost per BTU than propane, clean burning.

Cons: Not available in all rural areas. Requires a gas line installation, which can be expensive if the house is far from the main line. Prices can still fluctuate with market conditions.

Management tips: If you have access to natural gas, it is usually the most convenient and cost effective fuel. Check with your local utility about installation costs and any rebates for agricultural users.

Electricity

Electric heat is clean, safe, and requires no fuel storage. However, it is almost always the most expensive way to heat a broiler house on a per-BTU basis. Electric resistance heat converts electricity directly to heat, and that electricity costs more than the equivalent amount of heat from gas.

Pros: Clean, no emissions, no fuel storage, no delivery scheduling, simple equipment.

Cons: High operating cost, may require significant electrical service upgrades, can be unreliable during power outages.

Management tips: Electric heat is best used as a supplement or backup, not as the primary heat source for a commercial broiler house. If you use electric brooders, make sure you have a backup generator and that your electrical service can handle the load.

Waste Oil

Waste oil heaters burn used motor oil, hydraulic fluid, or other waste oils. They are common in shops and some poultry houses because the fuel is free or very cheap if you have a source of used oil.

Pros: Very low fuel cost if you have a steady supply of waste oil, reduces waste disposal costs.

Cons: Requires regular maintenance to clean the burner and filters. Fuel quality varies, and contaminated oil can damage the heater. Not all insurance companies will cover buildings with waste oil heaters. May not be allowed in all areas due to air quality regulations.

Management tips: If you use a waste oil heater, have a reliable source of clean, filtered oil. Install a good filtration system and follow the manufacturer's maintenance schedule closely. Check with your insurance provider and local air quality agency before installation.

Wood and Biomass

Some growers use wood-fired furnaces or biomass boilers to heat their poultry houses. These systems burn wood chips, pellets, or other biomass to heat water or air that is then circulated through the house.

Pros: Low fuel cost if you have access to wood or agricultural biomass, renewable fuel source.

Cons: High labor requirement for loading fuel and cleaning ash, less precise temperature control, may not be able to respond quickly to changing weather conditions, requires significant storage space for fuel.

Management tips: Wood heat is best suited to small operations or as a supplement to a gas system. If you use wood heat, install a backup gas or electric system so you can maintain temperature when you cannot tend the fire.

Sizing Your Heating System

Choosing the right size heater is critical. An undersized system cannot keep the house warm in cold weather, leading to chick stress and mortality. An oversized system cycles on and off too frequently, wastes fuel, and creates uneven temperatures.

Calculate Heat Loss

The first step in sizing is to calculate the heat loss of your house. This is a job for a heating professional, but you can get a rough estimate with a simple formula. Heat loss depends on:

The surface area of the walls, ceiling, and floor
The insulation value (R-value) of those surfaces
The difference between the desired indoor temperature and the coldest expected outdoor temperature
Air exchange rate from ventilation

A well-insulated broiler house needs about 20 to 30 BTUs per square foot of floor area to maintain 90 degrees F when the outside temperature is 20 degrees F. A poorly insulated house can need 40 to 60 BTUs per square foot. A typical 40 by 500 foot broiler house (20,000 square feet) needs between 400,000 and 1.2 million BTUs of heating capacity, depending on insulation and climate.

Match Brooder Capacity to Chick Numbers

For radiant brooders, the common rule is one brooder per 1,000 to 1,500 chicks. A standard 40,000 BTU radiant brooder can handle about 1,000 chicks during the first week. If you brood 20,000 chicks in one house, you need 14 to 20 brooders.

Account for Preheating

Radiant brooders are not efficient at preheating a cold house. They heat the litter and objects directly beneath them, but they do not heat the air. If you bring chicks into a house that is 50 degrees F, the radiant brooders will warm the litter to 90 degrees F, but the air a few feet away will still be cold. That cold air can stress chicks when they move away from the brooder.

Most growers use forced air furnaces for preheating. Start the forced air system 24 to 48 hours before chicks arrive to warm the whole house to 88 to 92 degrees F. Then turn on the radiant brooders a few hours before chicks arrive so the litter is warm. Once chicks are in the house, you can reduce the forced air heat and rely more on the radiant brooders.

Installation and Placement Best Practices

How you install and place your heating equipment affects how well it works and how safe it is.

Radiant Brooder Placement

Hang brooders 2 to 3 feet above the litter for chicks. Lower them to 18 to 24 inches during the first few days if the house is very cold.
Space brooders evenly across the brooding area. If you brood in only part of the house, place brooders in that area only and use temporary partitions to keep chicks contained.
Position brooders so their heat patterns overlap slightly. This prevents cold spots between brooders.
Keep brooders away from curtains, insulation, and other flammable materials. The recommended clearance is usually 18 inches or more.
Use chains or cables that are rated for the weight of the brooder. Install safety hooks or secondary supports so a brooder cannot fall if the primary support fails.

Forced Air Furnace Placement

Mount furnaces along the side walls, angled slightly toward the center of the house. This creates a circular air pattern that distributes heat evenly.
Keep the discharge of the furnace at least 3 feet above the litter to avoid blowing directly on chicks.
Install fresh air intakes on the outside wall so the furnace can bring in fresh air and mix it with heated air.
Make sure the furnace has proper clearance from walls, ceilings, and flammable materials. Follow the manufacturer's clearance specifications.
Install carbon monoxide detectors in the house and in any attached office or storage area.

Radiant Tube Heater Placement

Mount tubes parallel to the length of the house, spaced 10 to 15 feet apart.
Hang tubes 8 to 12 feet above the floor, depending on ceiling height.
Angle the tubes slightly downward toward the center of the house so heat radiates toward the birds.
Position the burner end of the tube where it is accessible for maintenance.

Thermostat Placement

Thermostats are the brains of your heating system. If they are in the wrong place, they will give false readings and your system will run too much or too little.

Place thermostats at chick level, which is 2 to 4 inches above the litter, not at human eye level.
Place them in the center of the brooding area, away from direct sunlight, drafts, and heat sources.
Use multiple thermostats in different locations and average their readings if possible.
Calibrate thermostats before each flock by comparing them to a known accurate thermometer.
Install a separate high temperature alarm and low temperature alarm so you know if the house gets too hot or too cold.

Temperature Management by Broiler Age

Managing temperature is not a set it and forget it job. You need to adjust the temperature as the chicks grow and as outside conditions change.

Week One

Start the house at 90 to 92 degrees F at chick level when chicks arrive. Some growers start at 88 to 90 degrees F and let the chicks warm the house. The key is to watch chick behavior and adjust accordingly.

If chicks are huddled together under the brooder, they are cold. Raise the temperature or lower the brooders.
If chicks are panting and spread out away from the brooder, they are hot. Lower the temperature or raise the brooders.
If chicks are spread evenly throughout the brooding area, some eating and drinking, some resting, the temperature is correct.

During week one, reduce the temperature by about 5 degrees F over the week. Many growers drop the temperature 1 degree F per day, from 92 degrees F on day one to 85 degrees F on day seven.

Week Two

Continue dropping the temperature about 1 degree F per day. By the end of week two, the house should be around 80 to 82 degrees F.

Week Three

By week three, chicks have feathers and can handle cooler temperatures. Drop the temperature to about 75 to 78 degrees F by the end of the week.

Week Four and Beyond

Continue reducing the temperature gradually. By week four, the house should be at 70 to 75 degrees F. By week five, 68 to 72 degrees F. By week six, 65 to 70 degrees F.

The exact temperatures depend on your climate, your house, and your bird strain. The most important thing is to watch the birds. They will tell you if they are comfortable.

Temperature at Bird Level vs. Ceiling Level

Remember that the temperature at chick level is what matters. The air near the ceiling can be 10 to 20 degrees F warmer than the air at floor level. If your thermostat is mounted at eye level, it may read 85 degrees F while the chicks are experiencing 75 degrees F. Always measure temperature where the birds are.

Nighttime Temperature Drops

In many climates, the temperature drops significantly at night. Your heating system needs to respond to those drops. If your system is sized correctly and your thermostat is working, it will cycle on more often at night. Check the house at night at least once during the first week to make sure the system is keeping up.

Ventilation and Heating: How They Work Together

Heating and ventilation are linked. You cannot manage one without the other. A broiler house needs fresh air to remove moisture, ammonia, and carbon dioxide. But bringing in cold outside air cools the house, so your heating system has to work harder.

Minimum Ventilation

During cold weather, run the minimum ventilation rate to control moisture and air quality without wasting heat. The minimum ventilation rate for broilers is typically 0.1 to 0.3 cubic feet per minute per bird, depending on age and outside temperature. Run exhaust fans on a timer so they cycle on and off, bringing in small amounts of fresh air each cycle.

Avoid Over-Ventilating

Running ventilation fans too much in cold weather wastes heat and dries out the litter. Dusty litter can cause respiratory problems in birds. Monitor relative humidity in the house. The target is 50 to 70 percent. If humidity is below 50 percent, reduce ventilation. If it is above 70 percent, increase ventilation.

Preheat Before Ventilation

When you bring in cold outside air, the heating system must warm that air before it reaches the birds. This means the heating system needs to be sized to handle both the heat loss of the house and the heat needed to warm incoming ventilation air. In very cold climates, this can double the heating load.

Use Radiant Heat to Offset Ventilation

Radiant brooders are ideal for cold weather because they heat the birds and litter directly, even when cold air is being brought in through the ventilation system. The air temperature in the house can be lower, but the birds are still comfortable because they are receiving radiant heat.

Common Heating Mistakes and How to Avoid Them

Even experienced growers make heating mistakes. Here are the most common ones and how to avoid them.

Mistake 1: Trusting the Thermostat Without Checking Bird Behavior

Thermostats can be wrong. They can be in the wrong location, miscalibrated, or fail entirely. The only reliable indicator of temperature is the birds themselves. Check bird behavior several times a day, especially during the first week.

Mistake 2: Heating the Air Instead of the Birds

Forced air furnaces heat the whole house, which wastes fuel. Radiant brooders heat the birds and litter directly. Use radiant heat for the chicks and forced air for preheating and backup.

Mistake 3: Hanging Brooders Too High

A brooder hung too high wastes heat because the warmth dissipates before it reaches the chicks. The correct height depends on the brooder model, but most radiant brooders should be 2 to 3 feet above the litter. Lower them if chicks are huddling.

Mistake 4: Ignoring Litter Temperature

The litter temperature matters as much as the air temperature. Chicks spend almost all their time on the litter in the first week. If the litter is cold, chicks will huddle even if the air is warm. Check litter temperature with a probe thermometer in several locations.

Mistake 5: Not Preheating Long Enough

The house needs to be at the correct temperature before chicks arrive, not after. Start preheating 24 to 48 hours before chick delivery. This gives the litter time to warm up and the house time to reach a stable temperature.

Mistake 6: Skipping Equipment Maintenance

A dirty burner can waste 10 to 20 percent of its fuel. A clogged filter can reduce airflow and cause the furnace to overheat. Clean and service all heating equipment before each flock.

Mistake 7: Not Having a Backup Plan

Heating equipment fails. Power goes out. Fuel runs out. Have a backup plan before you need it. This might include a backup generator, a spare heater, or an agreement with a neighboring farm to house chicks in an emergency.

Mistake 8: Ignoring Carbon Monoxide Risk

Any gas fired heater can produce carbon monoxide if it is not burning correctly or if it is not vented properly. Carbon monoxide is odorless and deadly. Install carbon monoxide detectors in the house and check them regularly.

Mistake 9: Setting the Temperature Too High

Many growers overheat their houses because they are afraid of cold chicks. Overheating is as bad as underheating. Chicks that are too hot pant, lose moisture, and reduce feed intake. Follow the recommended temperature curve and adjust based on bird behavior.

Mistake 10: Not Adjusting for Wind and Weather

A cold wind can increase heat loss from the house dramatically. Check weather forecasts and adjust your heating system before a cold front arrives. This might mean raising the thermostat setting or starting the backup heater.

Monitoring and Recordkeeping

Good recordkeeping helps you spot problems early and improve your heating management over time.

What to Record

Keep a daily log for each house that includes:

Date and flock age
Outside temperature and weather conditions
House temperature at chick level and at ceiling level
Litter temperature in several locations
Relative humidity
Heater settings and run times
Fuel usage and fuel deliveries
Chick behavior observations
Mortality counts
Any equipment problems or maintenance performed

How to Use the Records

Review your records weekly to look for patterns. If fuel usage is higher than expected, check for drafts, insulation problems, or equipment issues. If mortality spikes on a cold night, check your alarm system and consider adding a backup heater. If litter moisture is high, adjust your ventilation or heating settings.

Equipment Maintenance Log

Keep a separate log for each piece of heating equipment. Record the date of each service, what was done, and any parts replaced. Follow the manufacturer's recommended maintenance schedule.

When to Call a Professional

Some heating problems need professional help. Do not try to fix gas lines, electrical systems, or burner assemblies unless you are trained and certified.

Call a Heating Technician If:

The heater will not ignite or keeps shutting off
You smell gas or suspect a gas leak
The flame is yellow, smoky, or irregular
The heater makes unusual noises
The thermostat is not controlling the temperature correctly
You see soot buildup around the burner or vent
The carbon monoxide detector alarms

Call an Electrician If:

Circuit breakers trip repeatedly
You need to add new circuits for additional heaters
You suspect wiring problems
You are installing a backup generator

Call Your Extension Agent or Veterinarian If:

Chick mortality is higher than expected, especially in the first week
Chicks are huddling even though the temperature seems correct
You see signs of respiratory distress, such as coughing, sneezing, or gasping
You suspect ammonia levels are too high
You see signs of ascites or other cold stress related diseases

Decision Thresholds: When to Change Your Heating System

If you are considering upgrading or replacing your heating system, use these thresholds to guide your decision.

Consider Replacing Radiant Brooders If:

They are more than 10 to 15 years old and replacement parts are hard to find
Fuel efficiency has dropped noticeably
The canopies are corroded or warped
You are expanding your house and need more capacity

Consider Adding a Forced Air System If:

You struggle to preheat the house before chick delivery
You raise birds in very cold climates and radiant heat alone is not enough
You have high humidity problems that need supplemental ventilation

Consider Radiant Tube Heaters If:

You have high ceilings and want to reduce the number of heat sources
You are building a new house and want a more efficient system for grow-out
You want to reduce fuel costs for older birds

Consider Changing Fuel If:

Your current fuel price has increased significantly compared to alternatives
Your fuel supply is unreliable
You want to reduce your carbon footprint

Cost Comparison of Heating Systems

The cost of a heating system includes the purchase price, installation, maintenance, and fuel. Here is a rough comparison of the main systems.

Radiant Brooders

Purchase price: $300 to $800 per brooder, depending on size and brand
Installation: $50 to $150 per brooder for hanging hardware and gas lines
Maintenance: Low. Clean the burner and canopy before each flock. Replace thermocouples and gas valves as needed.
Fuel cost: Low to moderate. Radiant brooders are the most fuel efficient for brooding.
Lifespan: 10 to 15 years with proper maintenance

Forced Air Furnaces

Purchase price: $2,000 to $6,000 per furnace, depending on size
Installation: $500 to $2,000 per furnace for gas lines, electrical, and ductwork
Maintenance: Moderate. Clean burners, replace filters, check belts and motors before each flock.
Fuel cost: Moderate to high. Less efficient than radiant because they heat the whole air volume.
Lifespan: 10 to 15 years with proper maintenance

Radiant Tube Heaters

Purchase price: $1,500 to $4,000 per tube, depending on length and brand
Installation: $500 to $1,500 per tube for hanging hardware and gas lines

Installation: Minimal. Plug in or connect to gas line.
Maintenance: Low to moderate. Clean burners and check for carbon monoxide.
Fuel cost: High on a per-BTU basis.
Lifespan: 5 to 10 years

These are rough estimates. Actual costs vary by region, brand, and installation complexity. Get quotes from multiple suppliers before making a purchase.

Case Study: Retrofitting a Broiler House with Radiant Brooders

A grower in the Midwest had a 40 by 400 foot broiler house with four forced air furnaces. Fuel costs were high, and the grower struggled to keep litter dry during the winter. The grower decided to add 16 radiant brooders along the center of the house, keeping the forced air furnaces for preheating and backup.

The first flock after the retrofit showed a 15 percent reduction in fuel use. Litter moisture improved, and the grower noticed fewer foot pad lesions at processing. The radiant brooders paid for themselves in about three flocks through fuel savings.

The key to the retrofit was using the forced air furnaces for preheating and then turning them down to a low setting once the chicks arrived. The radiant brooders did the main heating work during the brooding period, and the forced air furnaces came back on during cold nights or when the birds were older.

Frequently Asked Questions

How many BTU do I need to heat a broiler house?

A well-insulated broiler house needs about 20 to 30 BTUs per square foot of floor area to maintain 90 degrees F when the outside temperature is 20 degrees F. A poorly insulated house can need 40 to 60 BTUs per square foot. For a 20,000 square foot house, you need between 400,000 and 1.2 million BTUs of total heating capacity. Have a heating professional calculate the exact heat loss for your house.

What temperature should a broiler house be for chicks?

Start chicks at 90 to 92 degrees F at chick level for the first few days. Reduce the temperature about 1 degree F per day, reaching about 85 degrees F by day seven, 80 degrees F by day 14, and 75 degrees F by day 21. Watch chick behavior and adjust the temperature based on whether chicks are huddling or panting.

How long should I preheat the broiler house before chicks arrive?

Preheat the house for 24 to 48 hours before chicks arrive. This gives the litter time to warm up and the house time to reach a stable temperature. The litter should be at least 85 degrees F when chicks arrive. Start the forced air system first to warm the air, then turn on radiant brooders a few hours before chicks arrive to warm the litter.

Can I use one heating system for both brooding and grow-out?

Yes, but you may need a combination of systems. Radiant brooders are best for the first week or two, but they do not heat the air well enough for older birds in cold weather. Many growers use radiant brooders for brooding and forced air furnaces for grow-out. Radiant tube heaters can handle both phases but may need supplemental heat for the first week.

What is the most fuel efficient way to heat a broiler house?

Radiant heating is the most fuel efficient because it heats the birds and litter directly instead of heating all the air in the house. Radiant brooders are the best choice for the brooding period. Radiant tube heaters are efficient for grow-out. The most efficient overall approach is to use radiant heat for the birds and forced air only for preheating and backup.

How do I know if my brooder is too low or too high?

If chicks are huddling directly under the brooder and not spreading out, the brooder is too high or the temperature is too low. Lower the brooder by 2 to 4 inches and check again. If chicks are panting and moving away from the brooder, it is too low or too hot. Raise the brooder by 2 to 4 inches.

What should I do if the power goes out during a cold night?

Have a backup generator that can power your heating system and ventilation fans. Test the generator monthly and keep extra fuel on hand. If you do not have a generator, have a plan to move chicks to a heated building or bring in portable heaters. Check on the house immediately and monitor chick behavior closely until power is restored.

How often should I service my heating equipment?

Service all heating equipment before each flock. This includes cleaning burners, checking gas lines for leaks, replacing filters, and testing thermostats. During the flock, check equipment daily for signs of trouble, such as unusual noises, yellow flames, or soot buildup. Follow the manufacturer's recommended maintenance schedule for your specific equipment.

Can I use a wood stove to heat a broiler house?

Yes, but wood heat has significant limitations. It requires frequent loading and ash removal, which is labor intensive. Temperature control is less precise because you cannot easily adjust the heat output. You also need a backup system in case you cannot tend the fire. Wood heat works best as a supplement to a gas system or for small operations.

What is the best way to reduce heating costs in a broiler house?

Start by improving insulation and sealing drafts. A well-insulated house needs much less heat. Use radiant brooders for the brooding period instead of relying on forced air. Reduce the temperature as the birds grow, following the recommended temperature curve. Keep ventilation at the minimum rate needed for air quality. Service your equipment regularly to maintain efficiency. And watch bird behavior to make sure you are not overheating the house.
