1. Product Overview

Thank you for choosing the JH 22B Series Carbon Fiber Infrared Heater. The far infrared radiant heater uses carbon fiber as the heating body, with a glass-ceramic panel. Its flat panel design uses radiant heat transfer, with rapid temperature rise — instant heating, soft light with no eye injury. When in use, the electric heating element directly transfers heat to people and objects by radiation, like sunlight.

With this radiant heating, the air does not produce convection, so the air stays fresh and clean. Indoor relative humidity can be maintained, and heat distribution is even, making people feel natural, fresh, comfortable and warm — like bathing in the sun.

2. Performance Features

⚡
