Why You Need To Repressurise Your Ideal Boiler

  • Maintains Efficiency - Your boiler needs the right pressure (1.0-1.5 bar) to circulate hot water properly.
  • Prevents shutdown - Low pressure triggers error codes (like F1) and can cause the boiler to shut down.
  • Compensates for water loss - Pressure drops naturally over time, especially after bleeding radiators or due to small leaks.

How To Repressurise an Ideal Boiler 

  • Turn off the boiler and let it cool
  • Check the pressure gauge (Should be between 1.0 - 1.5 bar).
  • Locate the filling loop - A silver braided hose with two valves under the boiler.
  • Open both valves slowly to let water in - You will hear it flowing.
  • Watch the gauge and stop at around 1.3 bar.
  • Close both valves tightly.
  • Switch the boiler back on and reset if needed.
