So I have been at my elderly grandparents over Christmas and noticed that the analogue pressure gauge under the boiler was noticeably swinging around a bit in the 1.5-2.0 Bar region whilst was the boiler was on. Is this normal or does it indicate a underlying issue? I read somewhere online...

I had a pressure gauge fail on a Worcester Bosch 30i gas boiler. The boiler is 7 years old and out of warranty so I didn’t have an issue paying for a replacement part and the fitting. I had the boiler serviced at the same time. All was well for a week then the replacement, WB OEM, gauge has...

Please can someone explain what sort of pipe runs a plumber would have made in this situation in a friend's house as it doesn't appear that it should work. A new system boiler was installed downstairs with internal pump, replacing an old heat only boiler that had a header tank in the loft. The...

I am trying to repressurise my boiler, this has previously been a routine task but the process I would usually follow isn't working this time. I have attached an image of the pipes and valves. Previously I would need to turn the blue and black valves nearest the loop, but this is not working...

Hoping someone can provide insight on issues as we've had plumbers come out 3/4 times and not being able to diagnose. 10 yr old boiler, Worcester Greenstar 25si , hot water runs fine, when heating turns on it causes a lockout/reset required, after 1-3 times of reset it then works fine. Pressure...

My 20 year old boiler is on its last legs, so am looking at replacing it. However I’m in a 3rd floor flat with a flue which goes out of the wall by a window. The boiler is by the wall so the flue is quite short. (I meant to post a photo but I don’t seem to have one, so I will post one tomorrow...

I have a Worcester Greenstar 4000 with a Worcester Greenstar Mini Magnet Filter.

Can someone tell me if the boiler looks okay?

I moved into a house which is heated by an old floor standing unvented gas boiler. When I light up the boiler, it makes a noise that is making me alarmed. It alternates between gas burning hum and a “blowing” sound, as if it was filling with gas. Is that normal? The control box is a Nova 820...
