System pressure above 1.5 bar — Heating system pressure too high

What does System pressure above 1.5 bar mean?

A pressure reading consistently above 1.5 bar, especially if approaching 2.5 bar, indicates the heating system pressure is too high. This can be caused by thermal expansion issues or other system faults.

• Heating system may be overfilled
• Faulty expansion vessel
• Overheating issue

Click steps to track your progress.

1. 1

   Check the pressure gauge on the F730.

2. 2

   If the pressure is above 1.5 bar, contact your installer. They will need to check the system, potentially by bleeding radiators or checking the expansion vessel.

3. 3

   Avoid attempting to bleed the system yourself unless you are experienced, as incorrect procedures can cause further issues.
