A leak is quite a common problem and is indicated by water forming a pool around the boiler, which could be an indication of a broken part or seal within the system. Strange sounds, like banging, whistling or gurgling, can be heard from boilers as well, and this indicates the presence of gas inside the system, low water pressure, or scale buildup hindering heat transfer.
