The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water). The make-up water is usually natural water either in its raw state, or treated by some process before use.
May 01, 2018 · All boiler manufacturers identify the “normal water line” in their instruction manuals. It is typically denoted as “NWL,” and describes the height in inches from the bottom of the boiler upto this line. By not paying attention to the NWL, you can set yourself up for a whole lot of headaches.
Jan 19, 2015 · The water pressure in a hydronic boiler shouldn't be over 12- to 15-psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12-psi setting will lift water 28' above the fill valve. A 15-psi setting will lift the water to 34'.
First, you have a BOILER there, not a furnace. A furnace heats and circulates hot air; a BOILER heats and circulates hot water. The sound of "running water or water trickling or rushing thru the pipes" is a classic symptom of AIR IN THE PIPING SYSTEM.
It does not leak when the boiler is not being fired, which would seem to indicate that the leak is above the water line or the leak only opens below the water line when under the influence of the heat of the direct fire. I suspect the leak is steam exiting a crack or hole above the water line.
