How to repressurise a boiler

What you'll need:

• If not integrated to boiler: Filling loop hose (braided metal hose with valves)
• Cloth or towel

Step-by-step instructions:

1. Locate the filling loop Find the filling loop - it's usually a braided metal hose with two valves, one at each end, located near the boiler.
2. In cases where the hose is not integrated: Attach the hose Securely attach both ends of the filling loop to the valves near the boiler, ensuring connections are tight.
3. Open the valves Slowly open both valves to allow water to fill the system. Keep a close eye on the pressure gauge throughout this process.
4. Monitor the pressure Let water flow until the pressure gauge reaches the green area, typically around 1.5 bar. Don't exceed the recommended pressure.
5. Close the valves Once the desired pressure is reached, immediately close both valves to stop water flow.
6. In cases where the hose is not integrated: Remove the hose Disconnect the filling hose and replace any valve covers that were removed.
7. Check the system Ensure the pressure holds steady. If pressure is too high, you may need to bleed some air or water from a radiator.
