Mondo Knows Facts

Panel radiators heat mostly by convection, not glow

Most of the output comes from air rising over the finned back plate A modern panel radiator has a flat front and a corrugated convector fin welded behind, which creates many narrow channels. Warm air rises through those channels and pulls cooler air in at the floor, so roughly three quarters of the heat arrives by convection and the rest by radiation. That is why radiators work best with clear space beneath them. It sits in Mondo's everyday life collection, one of 200 facts that each trace back to the reference below.
