1. Product Overview

The 13C Series radiant heater is designed with a specially coated aluminum radiation panel. The heat generated by the heating element is radiated directly from the panel surface and absorbed by people, walls, ceilings, floors, furniture, and other objects, creating a sun-like heating experience. Since it does not create air convection, it helps maintain clean indoor air and a comfortable humidity level.

2. Key Features
