Lastly, some boilers have a domestic hot water coil for making hot water for showers, washing dishes, so on and so forth. Sometimes, after prolonged use, a domestic coil inside the boiler jacket can develop a pinhole in the tubing. If this happens, the boiler pressure is affected by pressure from the domestic coil.
