OK. Pressure redone when boiler cold and not working. Set it to 1.5bar, as per the Heat Team engineer who came last week. That was yesterday morning (Monday). The heating seemed to come on OK and the system was quiet when I got home from work. However, my Fiancée was using hot water and there was staining on the wall outside where the pressure had exhausted. This was worse than previously noticed. The system was quite noisy with air and I noticed a little later that there was 0 pressure in the boiler.
I have a problem, don't I? What do you advise I do next? I do appreciate the help, by the way.

I do not know whether it is the right place to post my problem or not. I have a Baxi Combi boiler 105HE about 4-5years old and has started loosing pressure. When the heating is on the pressure is fine, but when no heating is on and the water on pre heat pressure bar is at 0, So I keep having to use the valves to increase the pressure about every 2 - 3 days? when the pressure is zero, it also makes rattling noise which is very annoying and disturbing. I have seem some water leakage from the outside overspill pipe, also bleeded all the raditors. Air was there, what it is still doing the same.
As suggest in this topic, expansion vessel might be a problem??? Is it expensive job, how much we looking for?
