Electric heater for heating a process fluid with a working fluid

A system, the system comprising:

• an electric heater for heating a process fluid, the electric heater including:
• a housing,
• an inlet for a process fluid and an outlet for the process fluid,
• an inlet for a working fluid and an outlet for the working fluid, and
• at least one electrical heating element configured to transfer heat to the working fluid within the housing;
• and
• at least one recirculation loop, the at least one recirculation loop including:
• at least one conduit, the at least one conduit fluidly connected to the inlet for the working fluid and the outlet for the working fluid.

A method of heating a process fluid, the method comprising:

• passing a working fluid into an inlet for a working fluid in a housing of an electrical heater, the housing including a first electrical heating element;
• passing an electric current into the first electrical heating element to heat the working fluid within the electrical heater to provide a heated working fluid;
• passing a process fluid into an inlet for a process of the electrical heater;
• and
• heating the process fluid within the electrical heater with the heated working fluid to provide a heated process fluid and a cooled working fluid.
