Outdoor wood boiler (OWB) insulated RAUPEX pipe is specially designed for the efficient transfer of hot water from outdoor wood boilers to residential and light commercial buildings. A flexible alternative to rigid pipe, OWB pipe offers ease of installation combines with the long-term performance of REHAU’s RAUPEX O2 Barrier PEXa pipe for hydronic heating applications.
OWB pipe consists of two carrier pipes surrounded by a solid layer of polyurethane foam insulation and protected by a polyethylene casing. The two pipe configuration combines supply and return pipes, streamlining installation. One of the RAUTHERM pipes is marked with a black line to differentiate supply from return. OWB pipes are available with 1” carrier pipes and coiled for shipment.
The following pressure and temperature limits apply to the application of OWB with RAUPEX pipe for conveying heating and cooling water at continuous operating temperatures with a 2.0 safety factor on allowable working pressure
