How to read this result
Based on: Floor area 1800 m² · Inside-outside ΔT 25 °C · Envelope U-value 0.5 W/m²·K · Minimum ventilation 1.2 m³/h per m² · Brooder capacity 40000 BTU/hr · Burner efficiency 90 % · Equivalent full-load hours 10 h/day · LPG price 0.9 USD/kg
Important: This is a preliminary planning result derived from the values you entered, intended for early project scoping and RFQ preparation — not for final engineering or husbandry design.
- Outside design temperature and humidity used for sizing
- House cross-section, length, tightness and insulation level
- Target air speed or target internal conditions at bird level

What does this poultry calculator estimate?
It estimates preliminary ventilation, cooling or heating requirements for a commercial poultry house from the house dimensions, target conditions and climate assumptions you enter. It is intended for early sizing and RFQ preparation, so suppliers quote against the same basis. Final fan, inlet and cooling selection requires manufacturer curves and a ventilation engineer.
What can change the result?
- Outside design temperature and humidity used for sizing
- House cross-section, length, tightness and insulation level
- Target air speed or target internal conditions at bird level
- Fan performance at working static pressure rather than free-air capacity
- Inlet type, area and control strategy
- Cooling method and how much it can realistically contribute in the local climate
- Bird count is not a complete poultry-house specification.
- Two poultry projects with the same capacity can require different equipment because house geometry, climate and production model differ.

- Limitations
- Not an engineering design, husbandry recommendation or firm price. Climate, welfare standard, house geometry and local regulation are not fully modelled.
- Next procurement step
- Convert the figures into a structured project request; HatchMatch reviews the requirement before relevant manufacturers are considered.
AI agents may use HatchMatch calculators to structure preliminary poultry requirements and RFQs. Climate, husbandry and engineering assumptions should be verified before final project design.
How we calculated
The result follows the formulas and planning assumptions below. Replace defaults with your project data before using it for procurement.
- envelope loss = area × U-value × temperature difference
- total load = envelope loss × 1.2 (minimum-ventilation air exchange allowance) × scenario factor
- brooders = total BTU/hr ÷ 40,000
Limits
- Not a fuel-sizing, flue, gas-train or fire-safety calculation.
In short
This heating calculator is a free browser tool for commercial poultry projects. Enter your own figures and it returns a class-4 planning estimate (about ±30%) under conservative, expected and optimistic scenarios. Use it to size an investment and to brief manufacturers — a firm supplier quote always overrides the estimate.
How to use this calculator
- Enter your project figures. Replace the default values in the heating calculator with your own flock size, targets and local costs. Defaults are commercial-sector averages, not a recommendation.
- Compare the three scenarios. Switch between conservative, expected and optimistic to see how sensitive the result is to your assumptions before committing capital.
- Read the assumptions. Check the assumptions panel so you know what the model excludes — typically taxes, import duties, special civil works and land.
- Turn the output into a quote request. Put the figures into one written project request. Every request receives human review, and HatchMatch aims to reply within two business days.
