Glow worm Combi 30ci

Hi

I have a Glow worm Combi 30ci which is about 2-3 years old. At the moment it has leak somewhere from the inside which is a steady drip at a rate of about a bucket a day. This is the second time i have had this problem about a year ago the same thing happened. An engineer came out and fixed it but the solution only lasted a year.

I have notice that on the rear wall of the property is an overflow pipe which has left some moisture on the brick work. It look like this has happened over a period time.

Any idea of what the problem could be?? Or what could be a more long term solution could be as paying £150 a year for an engineer will add up over the years.

Thanks for any help.

Are you losing central heating system pressure steadily?

If the system is not going then the pressure will go do right down and the system will not relight. at the moment it is coming on about every couple of hours.

Sounds like a leak on the heating side rather than the domestic hw. Unfortunately you need someone there to have a look as although we can suggest things we cannot see the leak

sounds like the presure vesel needs pumping back up to me, if there is no presure it will activate the releif valve, and also start leeking from the O rings.
