How to Repressurise an Ideal Combination Boiler

If the pressure on your Ideal Boiler has dropped and you're not sure what to do, this is the blog post for you. Have a look at the video below and step-by-step instructions. If you have any questions please feel free to get in touch. 

The system pressure gauge indicates the central heating system pressure. If the pressure is seen to fall below the original installation pressure of 1-2 bar over a period of time and continue to fall then a water leak may be indicated. In this event re-pressurise the system as shown below. If unable to do so or if the pressure continues to drop a Gas Safe Registered Engineer or in IE a Registered Gas Installer (RGII) should be consulted.

To Top up the system:-

1. Ensure both A & B handles (blue) are in the closed position (as shown below)
   
2. Remove the plug and cap and retain.
   
3. Connect the filling loop to the Domestic Hot Water (DHW) inlet and tighten. Also, ensure that the other end of the filling loop is hand tight.
   
4. Turn the Domestic Hot Water (DHW) Inlet A blue handle to the horizontal position.
   
5. Ensuring no leaks are seen, gradually turn the filling loop handle (blue) B to the horizontal position.
   
6. Wait for the pressure gauge to reach 1 to 1.5 bar.
   
7. Once pressure is reached turn valves A & B back to the closed position.
   
8. Disconnect the filling loop, replace the cap and plug. Note there can be some water spillage at this point.
