How Convection Heaters Work - Diagram & Explanation #3840334 (License: Personal Use)

The image is a technical line drawing of a convection heater, showing labeled airflow paths: cold air enters through lower inlets, passes over a heating element (implied by the central chamber), and rises as hot air exits through upper vents. Arrows indicate the cyclical motion driven by density differences-warmer, less dense air ascends while cooler air replaces it below. The design emphasizes passive, fan-free heat distribution.

Used on HVAC educational pages, product support sites, or DIY heating guides to explain natural convection principles; matches user intent seeking basic thermodynamics understanding or troubleshooting heater performance.
