摘要
A grass field such as a football playing ground comprises an underground heating and heat distributing plant below the uppermost growth layer (10). In order to provide a grass field built up, layer on layer, and heatable from below, as well as exhibiting a structure which will not be able to settle in the course of time, and wherein the pitch-corer substantially maintains its flat, plane, essentially horizontal original condition, the grass field is based on the use of air-carried heat energy, heated air being brought to distribute itself in a lower hot air distributing cavity layer covering the basal area of the pitch, and wherein some heat energy of the supplied air is liberated to wall faces (4, 5) defining said lower cavity layer, whereafter return air within an upper cavity layer assigned air communication holes (5') in a partition wall can be drawn off for reheating and reuse.
