Solar heat collecting and heating glass

The invention discloses solar heat collecting and heating glass, and relates to the field of solar energy utilization. The heat collecting and heating glass is double-layer vacuum glass, wherein one layer of the double-layer vacuum glass is transparent, and a heat preservation layer face, depending on vacuum, of the other layer of glass is provided with a solar energy heat absorption layer in a coating mode and absorbs solar energy for collecting heat and heating. The solar heat collecting and heating glass has the advantages of being simple in structure, low in acquisition and running cost, and convenient and practical to install. Furthermore, the solar heat collecting and heating glass can be installed on a wall, a window, a house roof, and a curtain wall to achieve heating, and a heat preservation tank can also be added on one side of a light collecting face so as to form solar energy augmented products such as a heating device and a dryer.
