Corrosion Leaks – From underfloor plastic tubing without oxygen diffusion barrier

What does Underfloor Heating Corrosion mean?

Using underfloor plastic tubing without an oxygen diffusion barrier directly connected to the boiler can lead to corrosion and leaks. This is explicitly stated as not covered under warranty. Oxygen ingress promotes corrosion within the heating system.

• Installation of underfloor heating systems with plastic tubing that lacks an oxygen diffusion barrier
• Direct connection of such a system to the boiler without a heat exchanger for separation
• Oxygen ingress into the heating system

Click steps to track your progress.

1. 1

   Identify if the underfloor heating system uses plastic tubing without an oxygen diffusion barrier.

2. 2

   If non-barrier tubing is present, ensure a heat exchanger is installed to separate this circuit from the main boiler.

3. 3

   Have a qualified professional inspect the system for signs of corrosion or leaks.

4. 4

   If leaks are detected, the system may require significant repair or replacement of affected components.
