In a Direct Fired Heater, the emulsion comes in direct contact with the firebox, or heating element.  In general, direct heaters are used to heat noncorrosive emulsions that are under comparatively low pressure.  Direct heaters, when operating under proper conditions, are the most efficient type of heater.  The efficiency of a heater is determined by calculating how much gas the heater burned to heat up emulsion to the desired temperature.

In an Indirect Fired Heater, the heat from the firebox is transferred indirectly through a water bath in the body of the vessel to the emulsion being heated in the tube bundle.
