Aug 19, 2020 · 5. The Hot Water Coil Has Developed a Pin In It. Some boilers have a tankless water heater or what is also known as a hot water coil. Sometimes, this coil will develop a pin in it, and this causes pressure to seep into the boiler and leads to leaks in the pressure relief valve. Turn off the water to the coil and check if the pressure stops rising.
In older hot water heating boiler expansion tanks that do not have an internal bladder to keep air and water separate, over time air in the expansion tank may become absorbed into the heating water. Air may also find its way via the heating water to other air bleeders or vents in the system.
