Description

RAUVIPEX UNO 25mm – 441003

RAUVIPEX UNO 25mm is a pre-insulated single pipe designed for underground heating applications where a single flow or return run is required. It is commonly used in buried heating pipework for small district heating systems, biomass boiler connections, and underground runs between buildings.

The pipe can be supplied in continuous lengths, allowing installation with fewer joints compared to segmented pipe systems. This can simplify installation and reduce the number of connection points along the pipe run. The outer casing is designed for buried conditions, while the insulation helps limit heat loss along the route.

The 25 mm size is typically used for shorter underground heating runs and smaller heat loads. It is well suited to connections between plant rooms and individual buildings, small outbuildings, or secondary heating circuits where space and excavation need to be kept to a minimum.

RAUVIPEX UNO 25mm is compatible with Rehau approved jointing and connection systems and is commonly specified where reliable single-run underground heating pipework is required with limited access for ongoing maintenance.
