Natural gas or propane direct fired heater has an open flame that provides a safe way to heat industrial and commercial areas by maintaining a proper air-to-fuel ratio. In a direct fired heater, the gas is fed directly to the burner while the airstream provides the needed oxygen for combustion. Air is forced through the burner baffle where it mixes with the gas.
The global Direct Fired Radiant-Convection Heater market size was estimated at USD 56 million in 2023 and is projected to reach USD 60.70 million by 2032, exhibiting a CAGR of 0.90% during the forecast period.
North America Direct Fired RadiantConvection Heater market size was estimated at USD 14.82 million in 2023, at a CAGR of 0.77% during the forecast period of 2025 through 2032.
