A system for heating drilling, completion, and/or stimulation fluids including acidizing liquids but not limited to; entering or exiting a wellbore, the system including a principal heat exchange vessel; a first inlet for introducing heat transfer media into fluid flow lines within the vessel; an outlet for flowing the heat transfer media from the vessel; a second inlet for introducing fluids returning from or returning to the well bore for receiving heat from the heating fluid within the fluid flow lines in the vessel; an outlet for flowing the heated downhole fluids from the vessel to be returned down the borehole; a heater for heating the heating fluid to a desired temperature before returning the heating fluid to the heat exchange vessel. Optimally, the drilling or completion fluid would be heated to 50° to 60° F. above ambient temperature.
