There maybe a .....

deposit of minerals and lime at the bottom of the boiler and it acts just like a fouled water heater. If it is a replacement boiler they often become the catch-all of the debris from the installation. If there has been an excessive amount of fresh water added it will be loaded with the minerals from the makeup water. I just replaced an electric boiler, no bigger than a bread box, just packed with lime. It popped and sizzled so bad the owners couldn't sleep at night. Short of boiling it out like a tea pot, it was best to replace it. Best Regards.

Depending on age

You could try one of several boiler treatment chemicals. I have had limited success again depending on age, better luck if it just started. Hercules boiler cleaner comes to mind.

I am reluctant to b ring this up but is there any piping buried under you concrete(copper under any of the floors). If there is(are) you may have a break in the piping and the homeowner doesn't notice hte change in boiler pressure because the make up device is doing it's job. Turn off your make up water and pray your pressure doesn't drop. I'll think of you in my prayers.:(
