The invention relates to a method of heating glass panels (3) for tempering. The horizontal glass panels (3) are heated in a lehr (4) by upper and lower convection blast and by upper and lower radiation heating, information representing a load of the glass panels (3) and used for the control and/or regulation of heating is read, the upper radiation heating is controlled and/or regulated in the way of a matrix by a profiling both in a conveying direction and in a direction lateral thereto. At least the upper convection blast is controlled and/or regulated in various sections of the lehr (4) in the way of a matrix by a profiling both in a conveying direction (K) and a direction lateral thereto, and that the relative blast effects of convection blowing elements (7a) successive in the conveying direction are regulated fo r a profiling in the conveying direction. The invention relates also to an apparatus applying the method.
