I was checking out a gas fired warm system for a new customer , so i tried to move a ceiling tile (2'x2') and I burnt my finger tips ( like 4 of em') . The ceiling tile is an electric infrared or radiant panel . That dam thing is HOT!!!!!! I have never run across one of these things, and it looks just like a regular 2x2 ceiling tile, same color and same texture as all of the other tiles
