ABSTRACT:
An apparatus for using solar energy to melt ice at low ambient temperatures on building roof eaves to provide a water run-off for melted ice which might otherwise freeze and backup under the roofing shingles thereby causing leaks in the building roof. An endless tube which is formed to have top and bottom tube loop ends connecting two intermediate elongated tube sections is filled with a fluid heat transfer medium and a solar collector is secured to the bottom tube loop end for solar heat transfer to the fluid. One of the elongated tube sections is covered with insulation. This device is secured to the upper side of a roof eave with the solar collector depending over the bottom edge of the roof eave for exposure to solar radiation. The heated fluid circulates up through the insulated portion of the endless tube and back along the uninsulated portion of the tube melting ice on the roof and providing a water run-off for the melting ice.
