How often should I need to top up the pressure in the heating system?

When the heating system is cool, the pressure should be between 1 and 1.5 bar on the pressure gauge (the indicator needle would usually be in the green section). If pressure is below 0.5 bar (down in the red section), water has been lost from the system and must be replaced. Note: The red part of the dial could also indicate the pressure being too high (about 2.75 bar or more). If the pressure gauge indicates high pressure as a result of over filling, you will need to bleed a radiator until the pressure gauge returns between 1 and 1.5 bar.

Read our guide on how to repressurise your system.

If pressure rises by more than 1 bar when the heating is up to temperature then the expansion vessel may require repressurising. This will require a service engineer. The pressure in the system will usually require topping up once or twice a year. If you are having to repressurise your heating system much more frequently, please contact your installer.

First, you will need to locate the filling loop, typically this is located alongside or below your system. 

If you cannot locate the loop, you may need to consult the manual or jump on our live chat and ask where it may be located.

Second, you will need to make sure that your system is cold and that your boiler is switched off.

On either side of the loop, there will be a lever, these are used to control the amount of water in the system. The more water in the system the more pressure.

It's very important that you keep an eye on the pressure gauge for the next step as if it gets too high or too low it can damage the system.

Thirdly, you will want to slowly turn either of these levers watching the pressure gauge closely as you do.
You will need to open both taps to balance out the pressure.

Once you have hit between, 1 and 1.5 bar then you will want to close the levers. Make sure these levers are fully closed as otherwise, pressure will continue to rise in the system.

Once this is complete it is safe to turn your system back on.

Should you ever accidentally overfill your system please get in touch with Gasway immediately.
