In the case of an electric duct heater the heat source would be the heating element the natural air flow being the fan assisted movement of air thru the duct.
Natural gas inline duct heater.
The gas flows through the coil and is heated up through the heat transfer by the aluminum encasing.
It is called heat exchangers and is one of the best methods to heat up the natural gas before transmission.
They have input ranges from 75 000 to 400 000 btu hr and can operate on either natural or propane gas with an airflow range from 556 to 14 500 cfm.
