The Flagro FVO-200RC 185,000 BTU Indirect-Fired Heater delivers dependable temporary heating for construction sites, warehouses, industrial facilities, and commercial buildings. Featuring a 23-gallon onboard fuel tank, 2,600 CFM airflow, and a recirculation hood, this portable heater is designed for demanding commercial heating applications.
The FVO-200RC operates on approved fuel oil, diesel, or kerosene and uses a 16-gauge 304 stainless steel heat exchanger to separate combustion exhaust from the heated supply air during normal operation.
Its integrated recirculation hood allows previously heated air to be returned to the heater through a 12-inch air inlet, potentially reducing heating demand in properly designed applications.
Equipped with a Riello burner, low-amperage blower, stackable frame, and flat-free wheels with locking casters, the Flagro FVO-200RC combines heating performance with convenient jobsite mobility.
The unit also supports approved ducting arrangements up to 150 feet, making it a versatile solution for temporary construction and industrial heating.

Indirect-Fired Heating with Recirculation
The Flagro FVO-200RC uses an indirect-fired heating system to provide warm air without intentionally introducing combustion exhaust into the conditioned airflow.
Unlike direct-fired heaters, the FVO-200RC transfers heat through a separate stainless steel heat exchanger.
During normal operation, the heat exchanger keeps burner combustion gases separate from the air delivered to the heated space.
Benefits of Return-Air Recirculation
The FVO-200RC includes a 12-inch return-air inlet designed for approved recirculating applications.
This allows previously heated air to be returned to the heater rather than relying entirely on colder surrounding air.
Potential benefits include:
- Improved temperature retention
- Reduced heating demand in suitable installations
- More consistent heating performance
- Flexible air-distribution configurations
- Potential fuel savings depending on operating conditions
Actual performance depends on outdoor temperatures, building heat loss, ventilation requirements, and ducting arrangements.
Important: The heater still requires adequate combustion air and safe exhaust venting. Return-air recirculation does not eliminate these requirements.
Common Applications for the Flagro FVO-200RC
Construction Site Heating
Commercial construction projects frequently require temporary heat during colder weather, building renovations, and HVAC installation.
The FVO-200RC provides portable heating for appropriately sized construction environments.
Typical applications include:
- Commercial building construction
- Winter construction projects
- Temporary construction enclosures
- Building renovations
- Jobsite maintenance
- Temporary heating during HVAC replacement
Warehouses and Industrial Facilities
Warehouses, manufacturing facilities, and industrial buildings may require supplemental heat during HVAC outages or scheduled maintenance.
With 185,000 BTU/hr of heating capacity and 2,600 CFM airflow, the FVO-200RC can support suitable temporary heating systems.
Its recirculation capability provides additional flexibility for installations with approved return-air ducting.
Temporary Structures and Commercial Tents
The FVO-200RC can support properly designed heating installations for temporary structures and commercial tents.
Its indirect-fired heat exchanger separates normal combustion exhaust from the supplied air.
Combustion exhaust must still be safely vented, and the installation must comply with applicable ventilation and fire-safety requirements.
Emergency Commercial Heating
The heater can also support temporary heating during:
- Permanent HVAC failures
- Industrial maintenance shutdowns
- Commercial building renovations
- Temporary work projects
- Seasonal heating demand
