Underfloor positionable membrane hose for maintenance of e.g. vegetation layers, has cavity for transporting fluids, where hose is provided over entire length of cavity in temperature control device
The hose (12) has a cavity (12c) for transporting fluids e.g. liquid/gas mixture, where the hose is provided over entire length of the cavity in a temperature control device (38). The temperature control device is provided with an electrical resistance heating wire (40) and an insulator (42) for preventing electrical or chemical reciprocal effect with the fluids, which are to be guided via the cavity of the membrane hose and the wall of the membrane hose. A coupling element is formed for making fluid connection and for connecting the temperature control device. Independent claims are also included for the following: (1) a system for maintenance of vegetation layers (2) a method for maintenance of vegetation layers.
