Agricultural Indirect-Fired Warm Air Heater AH
AH is an agricultural indirect-fired warm air heater designed for poultry houses, selected pig-house projects, greenhouses and other agricultural buildings.
It supports both gas and oil options and is especially suitable for projects that require broader main-space warm-air coverage and more flexible fuel adaptability.


What Is AH?
AH is an agricultural indirect-fired warm air heater intended for poultry houses, selected pig-house projects, greenhouses and other agricultural buildings. It is designed for projects that want to build the thermal environment of the main space through warm air, while also requiring stronger fuel flexibility through gas or oil options.
Who Is AH More Suitable For?
AH is more suitable for projects that care about main-space warm-air coverage, broader building adaptability and gas / oil fuel flexibility. It is especially relevant in poultry-house projects, selected pig-house projects and greenhouse projects where building scale and fuel conditions vary.
When Should You Consider AH First?
AH should be considered first when the project does not focus only on fast warm-up or only on poultry-house standardization, but instead needs a broader agricultural warm-air path with stronger fuel flexibility and better suitability for greenhouse and Middle East market conditions.
Core Advantages
Supports Both Gas and Oil
Better for Main-Space Warm-Air Coverage in Agricultural Buildings
Better for Poultry Houses, Greenhouses and Multi-Building Agricultural Projects
Better for Fuel and Building Condition Judgement
Typical Applications
Poultry House Applications
Suitable for selected poultry house buildings, especially projects focusing on establishing an overall thermal environment, stable airflow delivery, and long-term operational performance. For poultry house applications that prioritize airflow organization, warm air coverage, and fuel adaptability rather than only rapid temperature recovery, AH offers significant application value.
Greenhouse Applications
Suitable for flower, fruit, vegetable, and controlled agriculture greenhouses, focusing on warm air coverage, heat recovery efficiency, and large-area thermal environment establishment. For projects aiming to improve the overall greenhouse thermal environment through indirect-fired warm air systems while maintaining both gas and oil fuel options, AH is highly recommended for evaluation.

The application descriptions on the webpage are intended for preliminary evaluation. Actual equipment quantity, layout methods, and operating parameters should be further assessed according to project conditions.


How to Understand Agricultural Indirect-Fired Warm Air Heating
Agricultural indirect-fired warm air heating is a path that prioritizes warm-air quality and broader main-space coverage in agricultural buildings. AH should therefore not be understood only as a poultry-house heater. It is also a practical option for greenhouse projects and markets where fuel conditions vary significantly, especially where gas / oil flexibility is valuable.

How to Understand Model Selection and Configuration
Model / Capacity Range
Different AH models can be selected according to building size, heating load, crop or livestock type and project conditions.
Final selection should be confirmed based on actual project requirements.
Installation & Project Options
Fuel type, building dimensions, ventilation conditions and installation preferences all affect final model selection.
It is recommended to confirm the model, quantity and layout together with technical support.
How Does AH Differ from Other Agricultural Heating Paths?
Better for Main-Space Warm-Air Coverage
Better for Gas / Oil Dual-Fuel Logic
Better for Poultry Houses and Greenhouses in Middle East or Multi-Fuel Markets
Different from KWFP / KWIH / LTSA
Different heating solutions are not simply a matter of “which is better,” but rather which is more suitable for different agricultural building goals, fuel conditions, heating logic, and management requirements.
Frequently Asked Questions
Q: What applications is AH more suitable for?
A:It is suitable for poultry houses, greenhouses, and agricultural buildings requiring overall warm air coverage, especially projects focusing on whole-space thermal environment establishment, large-area airflow delivery, and indirect-fired warm air systems.
Q: What fuels can AH use?
A:AH can operate with either gas or oil depending on project conditions, giving it stronger adaptability across different countries, energy supply conditions, and agricultural projects.
Q: Why does AH provide greater value in poultry house and greenhouse projects in the Middle East?
A:Because the Middle East has a large number of poultry house and greenhouse projects with varying fuel conditions, building structures, and operational requirements. AH combines whole-space warm air coverage with fuel flexibility, making it more valuable in such markets.
Q: What is the difference between AH and KWIH?
A:Both belong to the indirect-fired warm air category. AH focuses more on whole-space warm air coverage for poultry houses, greenhouses, and selected agricultural buildings, while emphasizing gas/oil adaptability. KWIH focuses more on air cleanliness, warm air quality, and operational quality in poultry house applications.
Q: What is the difference between AH and KWFP?
A:AH focuses more on whole-space warm air coverage and indirect-fired systems while supporting gas/oil options. KWFP focuses more on direct-fired rapid heat recovery, system simplicity, and project economy.
Q: Why are all specifications and drawings not directly displayed on the webpage?
A:Because projects vary greatly in building dimensions, spatial characteristics, airflow requirements, fuel conditions, and operating environments. Website content is more suitable for preliminary evaluation, while detailed specifications, dimensions, and installation documents are better provided through project communication.
Q: What materials can Keywarm provide?
A: According to project requirements, Keywarm can provide one-page PDFs, product manuals, specification documents, and additional installation and product selection support.
Q: If I am still unsure whether AH is suitable for my project, what information should I provide first?
A:It is recommended to provide basic information such as building type, dimensions, height, space usage, fuel conditions, and operating methods. Based on this, we can assist with a preliminary evaluation closer to the actual application scenario.
