Suitable Applications and Compatibility

This barrier pipe is suitable for a wide range of domestic plumbing and heating projects, including wet underfloor heating systems, radiator circuits, and potable water distribution. Its flexibility makes it ideal for floor build-ups, screeded floors, suspended timber floors, and retrofit installations where ease of routing is important.

Compatible with a range of plumbing fittings and push-fit systems, the pipe can be integrated into new heating installations or system upgrades where reliable water flow and system protection are required.

Role In Underfloor Heating

Barrier pipe plays a critical role in wet underfloor heating systems by helping prevent oxygen permeation into the heating circuit. This helps reduce the risk of corrosion within system components such as pumps, manifolds, valves, and heat sources, improving system longevity and maintaining heating efficiency.

The pipe’s flexibility also supports quicker installation and smoother routing through floor constructions, helping installers achieve cleaner layouts with fewer joints and reduced installation time.

Guidance

Always install in accordance with current building regulations, manufacturer recommendations, and recognised plumbing practices. Ensure compatible fittings and system components are used throughout the installation. Pressure testing should be completed before final floor finishes are applied.

For wet underfloor heating applications, the pipe should be installed with the correct fixing system and spacing arrangement to achieve optimal heat distribution and system efficiency.
