Boiler Pressure

Hi Guys

Just a quick question I have a glowworm 30 ci combi boiler installed in my property the boiler is approx 2 years old. I had a small leak on two rads which I have tightend up but my boiler pressure had been slowly rising and now is at 2.6Bars when it had been at 1.5 Bars about 2 weeks ago.

Is there something I Am missing or should I just call BG an get them to do a repair for me ?

Is it ok to be using my boiler at this pressure ? any ideas how I can reduce the pressure ?


Cheers

If the pressure is increasing, check the tap that lets water into the system has not been left open/on. The pressure release valve should open at 3bar so the pressure doesn't go any higher than this.
Similar issue happened to us two weeks ago. Our boiler stopped working so we called out an engineer who fixed the original problem, but (which we found out later) had left the tap open and this caused the pressure to increase like is happening to yours.
I am not expert on heating systems so maybe someone else might be able to better advise you.

Edited to say that there is a pressure release valve (usually red) on the system and can be turned to drop the water pressure. However someone may come along and give you better advice.

Easiest way to reduce the pressure is by bleeding a radiator. If you have a radiator thats cold at top do that one, it will be air that comes out first. You'll need a bleed key and something to catch the water in. As above check that the fill tap is properly off

The Blue tap was ever so slightly not turned off so I have adjusted that as you suggest I also seen the red one but it didn't seem to drop the pressure so I will tryed a bleed some of the rads.

Im not used to CH Systems as I always had Electric or Warm Air Units so Im very worried of them for some reason I also cant seem to get enough hot water to run a bath up stairs my experiance with combi's so far has been rather poor.:(

The BG Engineer was saying this version of glowworm was just a very cheap put together boiler and no doubt will cause problems. He also went on to say BG sell and Install them and the engineers are complaining about it because the 30 ci model has a few issues and it makes them look terrible when customers have lots of problems.

When cold the pressure should be around 1 bar, it is normal for it to rise during the heating cycle.
If the pressure continues to rise when the heating is off then its either the filling loop not turned off or a problem with the pressure vessel in the boiler.
if thats the case you need help from a professional.
