Poultry house heating: costs, energy sources and how to cut them
Heat is the largest variable cost on a broiler farm — especially in the first days of rearing and during cold spells. Explore available systems, compare energy sources, and learn how insulation, controls and minimum ventilation affect FCR and flock health.

Why is poultry house heating so expensive?
On a typical broiler farm, heating accounts for 30–50% of total annual energy consumption. Costs are especially high in the first 7–14 days of rearing, when chicks cannot yet regulate their own body temperature and need an environment of around 33–35°C near the heat source. In winter and during cold snaps, heating may run almost continuously, and every degree Celsius held above the minimum costs real energy — which is why precise control translates directly into profitability.
Temperature in the first days of rearing — why preheating pays off
Preheating — warming the house 24–48 hours before chick arrival — does not just heat the air; it primarily warms the litter to at least 28–30°C. Newly hatched chicks seek warmth from the floor — cold litter delays feed and water intake, which worsens FCR throughout the entire cycle. The Aviagen Ross 308 management handbook explicitly lists floor temperature (not air temperature) as the critical parameter in the first days of life.
How heating affects flock health and FCR
Under- or over-heating is one of the most common causes of poor production results. Birds kept below the optimal temperature consume more feed to maintain body heat — FCR rises. Excessively high temperatures cause panting, limit feed intake, and can lead to mortality during hot weather. The correct temperature profile — declining as the birds age — combined with good minimum ventilation is the foundation of efficient rearing. More on ventilation: Broiler house ventilation.
Thermal insulation — the cheapest way to cut heating costs
Before deciding on an energy source or new heating system, check the insulation. The ceiling U-value should not exceed 0.2–0.25 W/(m²·K); walls 0.3–0.4 W/(m²·K). Leaky entrance gates, gaps in ventilation curtains, and missing vapour barriers can increase heat loss by tens of per cent. Sealing and insulation pay back in every heating season, regardless of the energy source used.
Zone controls and automation — the key to savings
Modern climate controllers can automatically follow a target temperature curve based on bird age, external temperature and humidity. Zone control — separate for entry zones, gable walls and the central section of the house — eliminates cold spots and overheated zones that cause uneven flock growth. More on optimal environmental parameters: Temperature and humidity in the poultry house.
Comparing energy sources for poultry house heating
Each source has different logistical, emissions and cost characteristics — the right choice depends on available connections, farm scale and risk profile.
Natural gas
The most convenient fuel where a gas connection is available. Gas burners and unit heaters have low emissions and are easy to automate. The price depends on the supply contract and changes seasonally, creating cost risk at high consumption levels.
LPG (propane-butane)
The solution for farms without a gas connection. An above-ground or underground tank provides supply independence. Propane prices are noticeably higher than natural gas, so choosing the right supplier and negotiating a contract before the season is essential.
Heating oil
Used less often — mainly as a backup fuel or where there is no gas or pellet infrastructure. Requires tank storage, regular servicing, and is sensitive to frost (wax). CO₂ emissions are higher than gas.
Coal and eco-pea coal
A traditional fuel, increasingly rare in large farms due to labour-intensive handling, storage requirements and emissions regulations. In small backyard houses it can still be cost-competitive if the boiler room is well insulated.
Wood pellets and biomass
A renewable energy source with lower life-cycle CO₂ emissions. Pellet boilers with automatic feeding require no continuous supervision. They do require a dry store of adequate capacity and regular cleaning. Fuel costs are generally more favourable than LPG at comparable output.
Heat pump
The highest energy efficiency (COP 2.5–4.5) with low operating costs. Requires a significant upfront investment and sufficient electrical connection capacity. Works best combined with underfloor heating and heat-recovery ventilation; however, the short production cycles in poultry farming limit the effectiveness of high-inertia underfloor systems.
Unit heaters, radiant heaters and underfloor heating — which to choose?
The heating system type determines heat distribution in the house, flock comfort and ease of operation.
Infrared radiant heaters (gas)
Emit heat directly into the bird living zone without heating the entire air volume. They respond quickly to setpoint changes, are relatively inexpensive to install and allow localised heating of specific zones. They require regular burner checks and emitter cleaning.
Forced-air unit heaters
Heat and circulate air throughout the entire house. They provide an even temperature distribution when directional nozzles are correctly positioned. Combined with a heat exchanger they enable heat recovery from exhaust air. Higher installation cost, but better humidity control.
Hot-water underfloor heating
Ideal for preheating — it warms the litter from below, which is especially important for chicks. The system’s thermal inertia means it must be started well in advance. The investment is costly, but reduces energy consumption over years of operation. Increasingly popular in new broiler houses.
Hybrid systems
Combine, for example, radiant heaters during the start phase with forced-air heaters during the grow phase. They allow cost optimisation across different phases of the cycle. They require an advanced climate controller that integrates both heat sources.
Frequently asked questions about poultry house heating
How much does heating a poultry house cost?add
Heating cost depends on many factors: the energy source and its current price, the building’s thermal insulation, the temperature profile for the species and age of bird, external conditions, and the efficiency of the heating system. There is no single figure — the key is monitoring energy consumption per production cycle and comparing results between cycles. Use the calculator: Broiler cycle profitability calculator.
What temperature should a broiler house be?add
In the first day of life, chicks need approximately 33–35°C near the heat source and a minimum floor temperature of 30°C. The target temperature is gradually reduced — by roughly 0.5–1°C per day — to approximately 18–20°C by the end of the cycle. Detailed temperature curves are set out in the genetics supplier’s management handbook (e.g. Aviagen Ross 308). Remember: observe flock behaviour — clustering near heaters means cold; spreading out and panting means overheating.
Is a heat pump suitable for heating a poultry house?add
A heat pump is the most energy-efficient option but requires a large upfront investment. In poultry houses it works best combined with underfloor heating and heat-recovery ventilation. Short poultry production cycles (5–6 weeks) limit the effectiveness of high-inertia systems. A cost-benefit analysis that includes electrical connection costs and financing should be carried out before deciding.
What is preheating and why does it matter?add
Preheating means warming the house 24–48 hours before chick placement. The goal is to achieve the correct temperature not just in the air but especially in the litter and any ventilation ducts. Newly hatched chicks seek contact with a warm floor — cold litter causes delayed water and feed intake, which results in worse FCR throughout the cycle. Aviagen and other genetics suppliers require litter temperature of at least 28–30°C at placement.
How can I reduce heating costs without changing the energy source?add
The first line of savings is sealing the building: check the condition of entrance gates, ventilation curtains, vapour barriers and roof insulation. Then calibrate the climate controller to follow a precise temperature curve — avoid excessive over-heating above the recommended norm. Ensure correct minimum ventilation: too little air causes humidity and CO₂ to rise, leading to respiratory disease — and treatment costs more than the energy saved on ventilation.

LPG or pellets — which is cheaper for heating a poultry house?add
The answer depends on local prices, availability and installation efficiency. Wood pellets generally have a lower unit energy cost than LPG, but require a larger storage area, regular boiler cleaning and some operator involvement. LPG is more convenient logistically, with prices varying by contract and season. When comparing both sources, consider: boiler/burner efficiency, installation costs, equipment depreciation and price change risk. The optimal choice varies between farms.
