electric heater, device for heating rooms that converts electric current to heat by means of resistors that emit radiant energy. Resistors may be composed of metal-alloy wire, nonmetallic carbon compounds, or printed circuits.

How does PTC heater work?

PTC heaters utilize Positive Temperature Coefficient materials i.e. materials that exhibit a positive resistance change in response to the increase in temperature. … Simply put, the material allows current to pass when it’s cold, and restricts current to flow as the threshold temperature increases.

How do I calculate what size heater I need?

1. Multiply the length times the width times the height to calculate the volume in cubic feet.
