Jul 02, 2016 · The low melting point (tin or lead) does not melt till the upper surface of plug is submerged in water. But in case of water level in boiler falls below the danger levels, the fusible plug uncovered by the water and get exposed to steam. This overheats the plug and the fusible metal having low melting point which melts quickly.
Air exit tanks on heating boilers and circulator pump mounting location - some heating boilers use an air exit tank mounted on the hot water header above the heating boiler to combine the function of an Expansion Tank with the Air Bleeder Valve or air purge valve to rid the hydronic (hot water) heating system of un-wanted air. Air in the heating system will often rise to a high loop of radiator or heating baseboard piping where it will block the flow of hot water, leading to an air-bound
The good news is that boilers are actually very simple, which means there’s not much to go wrong.
