RAUVITHERM is a pre-insulated PE-Xa pipe for district heating, biomass, biogas and heat pump applications. It has proved immensely popular since its launch due to its high district heating pipe rehauflexibility and easy to use REHAU EVERLOCâ„¢ jointing system. Mibec can supply REHAU district heating pipe throughout the UK and Ireland.

In their constant drive to reduce their carbon footprint, REHAU has begun manufacturing RAUVITHERM in the UK. The pipe is supplied in project-specific lengths to reduce any wasteage on site.
