VAILLANT BOILER LEAK

[klebe22]

I have a Vaillant VC GB 182EH bolier, 15 years old. It has developed a slight leak - 2 or 3 drips per minute. No change in the sound of the boiler. It seems to be coming from a joint in the lower part of the boiler but I am worried it is a heat exchanger leak. How do I tell if this is the case ? Is it safe to leave on, there is no loss of pressure and heating and hot water are fine.

No loss of pressure says it's on the domestic side, if the drips are central I would suspect water section, if on the far left the secondary h/ex would be prime suspect, of course it might be just a nut needs tightening.
As for the dangers - if water is not dripping/pooling on or near anything electrical you should be safe.

the 182 is a system boiler so any water leak should be a system pressure loss ? any leak needs sorting it wont get any better

If that is so, then my post is total b0ll0X.
