How To Repressurise Your Boiler
If your heating is not working as well as it should be, you may need to repressurise your boiler by adding cold water from the mains.
Repressurising your boiler is simple to do and only takes a few minutes. The video below and the guide that follows will outline the general steps for repressurising your boiler.
Repressurising Your Home’s Boiler
Turn off your boiler and make sure it is completely cooled down. Then, identify if your boiler has an external or internal filling loop (or hose).
A boiler's working pressure is between 1 and 1.5 bar, but check your manufacturer's manual for specifics.
For boilers using external filling loops
Attach one end of the loop to the mains valve and the other to the boiler system valve. Open the main water tap. Then slowly open the boiler tap to let the water into the system.
Let the boiler fill up until the pressure level is at the working pressure of 1 to 1.5 bar. Once done, close the taps and disconnect the loop.
For boilers using external filling loops
Locate your boiler's filling point—this will be either behind a removable panel on the front of your boiler or underneath a screw-down cap on top of your boiler. Slowly turn the knob or screw clockwise until water starts coming out of the filling point.
Once the water starts coming out, continue turning until you reach the desired pressure (between 1 and 1.5 bar). Once you have reached the desired pressure, turn off the water supply and screw the cap back on tight.
Repressurising Your Boiler Again In 12 Months?
Please note that repressurising your boiler should normally happen only once in 12 months. But if your boiler loses pressure and you find that you are having to repressurise it more than once, then please contact us on 01522503717 and we will be able to send out a contractor to check your system. However, if it is found that it falls under your responsibility as a tenant then you will be charged for the work.
Reminder That You May Be Charged - Where our contractor has arranged a time with you to attend and you postpone, cancel, or don't show up or where it is your fault for the appointment not proceeding you will be responsible for paying the call-out charge for the contractor and potentially any restocking fee for parts. Where the fault, issue or damage, is put down to your or other tenants, permitted occupiers, or guests' actions, you will be responsible for paying for the repair. These terms are already part of your Tenancy Agreement.
