The soil heater has a circuit for heat carrying fluid (2) mounted on the lower face (1) of the soil which is not thermally isolated, forming the base of the locality (3) in which the soil is to be heated. There is a layer of thermally reflective or insulating material (4) situated under the circuit and forming a barrier between the latter and the lower area. The circuit can be directly fixed on the floor of the lower section It is formed by a tube of polymer material formed as a serpentine shape with parallel sections held against the floor by metal rails (5) which are mutually spaced. |
