Boiler pressure problems

If your boiler is experiencing boiler pressure problems, it will not work effectively. And eventually, may stop working altogether. That’s why, as part of your regular boiler maintenance, you should always check on your boilers pressure gauge. Your boilers pressure should be around 1 bar, where it should have been set on installation of your boiler. You can usually find the gauge on the front of your boiler. Or you can check your manual or boiler handbook to find out where it is.

A boiler with pressure that has dropped below one bar, could mean that there is a leak in your central heating, or hot water systems. And you will find that it takes a long time for you water to heat up, or your radiators will only be lukewarm.

At the same time, a boiler with pressure that is increasing, could be costing you a fortune on wasted fuel. You might find that your shower is suddenly incredibly hot.

If you are having boiler pressure problems, and your pressure has dropped below 1 bar, you can try and reset the pressure yourself by:

  1. Switching off your boiler and allowing time for everything to fully cool down
  2. Finding the filling loop hose and making sure both ends of this are fully attached and connected to the valves.
  3. Slowly and carefully opening the valves and allowing cold water from the mains to enter the system. You will be able to hear the water flowing in.
  4. Closing the valves carefully once the boiler pressure reaches 1 bar.

Once you have completed these steps, the boiler pressure should remain level. If it drops again, you will need to contact the professionals.
