Now you might be thinking how to repressurise a Glow worm cxi boiler?

You just need to follow certain easy steps in order to deal with the method of re-pressurizing.

  1. Close all the vents

Before getting start with re pressurizing your boiler, check all the bleed valves on radiators and towel rails to be fully closed.

  • Search for the filling loop

In most of the boilers, they have the external filling loop that is used to top up the boiler with water and hence increases the pressure.

  • Open the filling loop

As soon as you open the filling loop, you will get to see a pressure rise. You can take a look of what is the exact pressure your boiler needs. Commonly the boilers operate with 1.5 bars.

  • Close the filling loop

Make sure that the filling loop is completely closed. However if it is not closed it will slowly leak additional water into the boiler. This will increase the pressure and the boiler will lockout.

Note –If there is no filling loop in your boiler, they might be installed on the cylinder.

Warning

If you have re pressurized your boiler too much you will need to drain the system. But if the pressure is very high by less than 0.5 bars, you need to understand the problem by bleeding radiators. You just need a bleed key, a bucket to catch the water and towel to protect carpets. Now open the bleed valves very slowly. This will allow the water to escape and pressure to be released.
