Exacon MultiHeat Hot Water Heater
Efficient, Even Heating for Commercial Poultry Barns
The Exacon MultiHeat Hot Water Heater is a high-efficiency agricultural heating unit designed to distribute warm air evenly throughout commercial poultry barns. Using hot water supplied by an external boiler, the MultiHeat system combines a heat exchanger, axial fan and six-outlet air distribution design to help maintain consistent barn temperatures without an open flame inside the heating unit.
Designed for demanding poultry production environments, the MultiHeat Hot Water Heater circulates heated air horizontally across the barn, helping improve temperature distribution, manage moisture and support suitable conditions for bird development.
With heating options advertised up to 375,000 BTU, durable ABS construction and optional adjustable air diverter flaps, MultiHeat offers a flexible solution for poultry producers looking to improve heating efficiency and environmental control.
Key Features & Benefits
- High-Efficiency Heat Exchanger: Transfers heat from an external hot water supply to the air circulating through the poultry barn.
- Six-Outlet Air Distribution: Distributes warm air horizontally in multiple directions to help maintain consistent temperatures throughout the building.
- No Open Flame: Uses an external hot water source rather than combustion inside the heating unit, eliminating direct combustion emissions at the unit.
- Up to 375,000 BTU Heating Capacity: Offers high-capacity heating options for commercial poultry production, with actual output depending on model and operating conditions.
- Axial Fan Technology: Draws barn air through the heat exchanger and circulates warmed air throughout the poultry house.
- Optional Adjustable Diverter Flaps: Stainless steel flaps allow producers to adjust airflow direction, change air throw or close individual outlets.
- Up to 50-Foot Air Distribution: Designed to deliver warm air across distances of up to 50 feet, supporting wider poultry barn layouts.
- Durable ABS Construction: Features a heat-resistant, ammonia-resistant ABS housing suited to agricultural environments.
- Reduced Moisture Production: Does not introduce combustion-generated water vapour directly into the barn, helping support litter moisture management.
- Improved Litter Conditions: Even heating and moisture management can help maintain drier litter when combined with appropriate ventilation.
- Potential Ventilation Energy Savings: Avoiding direct-fired combustion emissions may reduce the ventilation required specifically to remove heater-generated moisture and carbon dioxide.
- Heating and Cooling Capability: Can also operate as an air-cooling unit when supplied with suitably chilled water.
- Easy-Clean Design: Features an accessible click-system construction that simplifies cleaning without complete disassembly.
- Flexible Fan Options: Available with single-phase or three-phase fan configurations, with compatible frequency-drive control options.
How the MultiHeat Hot Water Heater Works
The MultiHeat system uses a hot water heat exchanger and forced-air circulation to distribute heat throughout a poultry barn.
Step 1 — Hot Water Supply
Hot water is supplied from an external boiler or compatible hot water heating system.
Step 2 — Heat Transfer
The hot water passes through the MultiHeat heat exchanger, transferring thermal energy to the surrounding air without direct combustion inside the unit.
Step 3 — Air Circulation
An integrated axial fan draws air from inside the poultry barn through the heat exchanger.
Step 4 — Six-Way Heat Distribution
The warmed air is discharged horizontally through six outlets, helping distribute heat across the barn.
Step 5 — Airflow Adjustment
Optional stainless steel diverter flaps allow airflow direction and distribution to be adjusted according to the building layout.
Step 6 — Continuous Air Recirculation
As warm air moves through the barn and rises, it can return toward the unit for further circulation. An optional recirculation duct can support this airflow pattern.
