When installed, the bridging phenomenon does not occur even when the snow is under the pressure of falling roof snow, so the snow melts naturally without having to break it up with a shovel or the like.

3. When installed in front of a garage, etc., the frame is made of parallel heating medium liquid circulation pipes, etc., so cars can pass over the panel without slipping.

4 When the snow melts, the thermostat cools in the outside air and opens, allowing the remaining hot water inside the panel to drain naturally and prevent it from freezing.
