hi all - thanx for any help ,
i have a one pipe steam heat system that is about 30 years old ...
im trying to figure out the ideal water level to keep in the boiler ,
my hartford loop comes back into the supply line about 6 inches above
where the supply line goes into the boiler tank ... if i open the
drain that is along the lowest section of the hartford loop and slowly
fill the boiler until water flows steadily out of the loop drain is
that a good way to figure out the highest amount of water i would want
in the boiler ?
i mean - if it is overflowing into the return loop then the boiler
cant get any more full right ? unless there is some hidden plumbing
that i dont understand that can effect things ... ? should there
always be a certain level of water in a hartford loop during the
heating season ?
when i did it this way the water in the sight tube was about 1/3 of
the way up the tube , so i marked it and am figuring that this is the
highest i ever want to fill the boiler ...
can i safely check my low water cutoff by just cranking the thermostat
and slowly draining water out of the boiler until the burner shuts
down ? should it theoretically shut down before there is water reading
in the sight tube ? what if the water level drops completely out of
sight in the tube ? can i continue on until it shuts itself down or
stop there ?
thanx for any help ...
