Rust in water cause surging?
I have a Dunkirk MODEL PVSB boiler. Its about 12 years old and appears to be installed correctly based on articles on this site.
I was reading your article on
tuning the heating system were you talked about the causes of wet
steam. When the boiler is running, the water in the sight glass bounces
up and down about 1.5 to 2 inches. You called this surging. I
followed your recommendations on skimming during which I let the water
run through the bpiler for 3 hours and then boiled some where it did not
foam. The boiler still surges. When I drain the boiler, the first
half gallon is very brown from rust, and then runs fairly clear. I
drain it every day with the same result. Can the rust in the water be
the cause of the surging?
Also, I have twice drained the return where
there is a lot of rust colored water. What do you recommend on how to
remove the rust? Thanks!
