How Home Heating Systems Work - Visual Guide to Radiator Efficiency #3643639 (License: Personal Use)

This flat-style illustration depicts a house cross-section with a central radiator emitting warm air (shown as red wavy lines), illustrating convection-based heating. Snowflakes outside emphasize cold external conditions, while steam from the chimney indicates active combustion or boiler operation. The image highlights thermal dynamics, including heat loss through the roof and walls.

Used on HVAC educational pages, energy-efficiency blogs, or home improvement sites to explain basic heating principles; targets users searching for “how radiators work,” “home heating diagrams,” or “winter insulation tips.”
