Brooders and heaters — warmth at the start of a flock
The first days decide the whole batch. A chick cannot yet regulate its own temperature, so the equipment has to provide the heat. We explain how a brooder differs from an air heater, how to size the output and how to set heating to the birds’ age.

Heating a poultry house is two different jobs. A brooder heats locally — it warms the litter and the chicks directly beneath it, like the sun. An air heater heats the whole hall, raising the air temperature across the building. At the start of a flock you usually need both: brooders create warm zones where chicks gather, while the air heater holds a background temperature in the rest of the house.
Brooder or air heater — how do they differ?
A brooder (gas, electric or ceramic) works like an infrared heater: it warms what sits beneath it, not all the air. The chicks themselves choose how close to the source they want to be — the best thermometer on the farm. An air heater is a burner with a fan that mixes and warms the air of the whole hall. Brooders are precise and economical when starting few birds over a large floor; air heaters even out the temperature and cope on freezing days.
How a poultry house is heated
The choice depends on the available fuel, the size of the hall and how brooding is run.
Gas brooders (infrared)
The most common choice at the start. A gas burner heats ceramic or mesh that glows in the infrared and warms the litter beneath. They create a clear warm zone where chicks gather. They require a gas installation and good ventilation.
Electric and ceramic brooders
An electric heating element or ceramic panel. They produce no flue gases or moisture, so they don’t load the ventilation, but electricity costs more than gas. They suit smaller buildings and places without a gas supply.
Gas air heaters with a fan
They heat the air of the whole hall. In the direct version the flue gases enter the house (lots of heat, but rising moisture and CO2); in the indirect version the gases leave through a flue — more expensive, but the air stays clean.
Oil or biomass heaters
They heat the air through an exchanger (indirectly), so the flue gases don’t enter the hall. Lower fuel cost at the price of handling and storage space for the fuel. Popular where gas is expensive or unavailable.
Control and heating zones
It pays to split heating into zones and connect it to a climate controller. The controller switches heating by a temperature sensor and the birds’ age — and shuts it off once the birds warm the hall themselves. That is a real fuel saving.
Safety: CO and gas
Every combustion consumes oxygen and produces carbon monoxide. CO and gas sensors, working minimum ventilation and burner servicing are not an extra but a condition of safe operation — for the birds and for people.
Heating step by step
- 1
Calculate the heat demand
Heating output is matched to the volume of the hall, the building’s insulation and the lowest expected outdoor temperature. The worse the insulation and the harsher the winter, the more kilowatts you need. Manufacturers give rough output figures per square metre — treat them as a starting point, not a certainty.
- 2
Choose the fuel and the equipment type
First check what you have: natural gas, LPG, electricity, oil or biomass. The fuel determines the equipment type more than anything else. At the start brooders (warm zones) are usually combined with an air heater (background heat).
- 3
Position evenly and set zones
Place brooders so the warm zones overlap and leave no cold gaps. With ring brooding (chicks are confined to a smaller area at the start) the heat sources go in the centre of the ring. Avoid blowing cold air straight onto the chicks.
- 4
Set brooding temperatures by age
On day one a chick needs it warmest (around 33–34°C in the zone under the brooder), and the temperature is then lowered gradually each week. The best indicator is the birds themselves: evenly spread = right, huddled together = cold, fleeing the source = too hot.
- 5
Integrate with climate control
Connect heating to the controller together with ventilation. Heating and airing must work in concert — otherwise the heater and the fan fight each other and waste fuel. A good controller runs the temperature curve automatically by flock age.

Mind servicing and safety
Before every placement check the burners, nozzles, gas installation and CO sensors. A dirty burner heats worse and produces more carbon monoxide. Plan minimum ventilation so it removes flue gases and moisture even on freezing days.
Frequently asked questions about poultry house heating
Brooders or air heaters — which to choose?add
Most often both. Brooders give point warm zones ideal for starting small chicks and let them choose their own thermal comfort. An air heater holds the air temperature of the whole hall, especially on freezing days. Combining the two gives the best control and the lowest fuel use.
What temperature under the brooder at the start?add
In the zone under the brooder on day one you usually aim for around 33–34°C, lowering it gradually in the following weeks. Exact values depend on the species and the chick supplier’s guidance. The surest check is the birds’ behaviour: evenly spread chicks mean the temperature is right.
Is gas heating safe for the birds?add
Yes, provided ventilation and sensors work. Burning gas consumes oxygen and produces carbon monoxide and moisture. Direct gas heaters need minimum ventilation that removes the flue gases; where you want completely clean air, indirect units with the gases vented outside are chosen.
How do I size the heating for my poultry house?add
The starting point is the volume of the hall, the quality of insulation and the lowest outdoor temperature of the season. Manufacturers give rough output figures per square or cubic metre. With poor insulation or a harsh winter add a margin. The final choice is best confirmed with the equipment supplier.
