Expansion tanks: how to diagnose & bleed a waterlogged hot

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.

Industrial boiler technology for beginners

On the front of the boiler is an external reversing chamber, which again reverses the flue gases and leads them to the end of the boiler in the 3rd smoke tube pass. Hot water boilers are normally completely filled with water during operation. Steam boilers on the other hand are only 3/4 filled with water; the upper quarter is the steam space.

Boiler Gauges, how to read the temperature & pressure

Heating boiler gauges: this article describes the combination pressure & temperature gauge found on most hydronic (hot water) heating systems. The boiler gauge gives helpful temperature or pressure readings that tell us if the boiler is operating normally. The same pressure and temperature readings at a boiler can help diagnose problems such as TP valve leaks, cold radiators, and even boiler
