<p>The invention relates to a soil-heating device, particularly for soil covered by a synthetic surface, of the type comprising a heated film (1). Said device is characterised in comprising two sealed and electrically-insulating support sheets (1a, 1b; l'a, l'b), between which parallel conducting resistive strips (3,3') are arranged over the length of the support sheet in pairs, such that, at one end (B) said strips are connected to two electrical supply connectors (L, N) and, at the other end (A), connected to each other by means of a conducting bridge (9).</p> |
