The heating pipe

The heart of the System 70 is the DUO 17 Pipe developed especially for this system. It consists of a water conducting PE-X internal ribbed pipe. The special feature of the DUO 17 heating pipe is its structure. The air gap surrounding the water conducting pipe is used as a precisely defined heat insulation. This means that the System 70 underfloor heating system can be operated using a considerably higher feed temperature than conventional systems. Underfloor heating and radiators can therefore be operated at the same water temperature. As such, the ROTEX System 70 only needs a heating circuit where other systems require additional water distribution.

The DUO 17 heating pipe is used in the System 70 both for the underfloor heating and to connect radiators. Moreover, the ribbed jacket of the DUO 17 heating pipe provides additional safety during installation and operation.
