If your Worcester Bosch boiler is losing pressure, you might notice your heating system not working as efficiently as it should. Don’t worry—re-pressurising your boiler is a straightforward process you can handle at home with a little guidance.

This step-by-step guide will walk you through re-pressurising your Worcester Bosch boiler safely and effectively.

Why Do Boilers Lose Pressure?

Boiler pressure can drop for several reasons, including:

  • Small leaks in the system
  • Bleeding radiators
  • Faulty components

If you notice the pressure gauge reading below 1 bar, it’s time to re-pressurise your system.

What You’ll Need

Before starting, gather the following items:

  • A filling key (usually provided with your boiler)
  • Access to the filling loop

Step-By-Step Guide To Re-pressurise Your Boiler

  1. Turn Off Your Boiler
    Switch off the boiler and allow it to cool down for safety.
  2. Locate The Pressure Gauge
    Find the pressure gauge on the boiler’s control panel. Ideally, the pressure should be between 1 and 1.5 bar.
  3. Find The Filling Loop
    Locate the filling loop—this is usually a silver, flexible hose beneath the boiler.
  4. Insert The Filling Key
    If your boiler uses a filling key, insert it into the designated slot and turn it to unlock.
  5. Open The Valves
    Slowly open the valves on the filling loop. You’ll hear water flowing into the system.
  6. Monitor The Pressure
    Keep an eye on the pressure gauge and close the valves once the needle reaches the recommended level (around 1.5 bar).
  7. Remove The Key And Check For Leaks
    Remove the filling key, tighten the valves, and check the system for any leaks.
  8. Turn The Boiler Back On
    Switch the boiler back on and check its performance.
