      For it to be &quot;infrared&quot; I would expect the panel to be insulated from heat loss to the surrounding air. This is how infrared cooling panels work, but the principle should apply (actually more!) for heating panels.

      It&#x27;s unusual thinking of heating the air as &quot;loss,&quot; because normally we would say any heat loss still heats the room, but infrared heating is used precisely because heating air is relatively inefficient: less heat reaches the skin, which is all that really matters!

      For low cost and ease of use, chicken heater bulbs continue to be quite efficient IR sources.
