A method and a device for warming the surface of a road. The device comprises a sealed thermosyphon having an elongated condenser unit adapted to be positioned on an insulated layer just below a road surface. The device further includes an evaporator containing an easily evaporatable liquid, which is connected to the condenser and situated at a lower level thereto. When the temperature of the evaporator is above the boiling point of the liquid, the liquid will evaporate and the condensed vapor will move up into the condenser where it will condense and flow back down to the vaporizer. The condensation of the liquid causes heat to be transferred from the device to the area adjacent the road surface.
