Boiler sluggish, Safety Valve went off!
Hello, I purchased a Home in Queens in 2009. (Built 1939) with a new Burnham boiler (Gas/Steam 1 Pipe) installed 2007. It seemed properly installed as per Dan's Steam Night Class. About two weeks ago, my wife put thermostat to about 80'. I asked her 2 lower it (my mom complained to HOT!) (over the phone, wife refused to lower temp) When I got Home, (2 am) the LWCO kicked in and was auto feeding. I waited a few minutes, and set thermostat back to our normal 70 Degrees) Fast Forward two weeks, I do my Bi-weekly check and find out the boiler glass was overfilled (I drained in a Bucket to mid level) it had real dirty/lurky/cloudy water. Recently, (today, 3am) with the current Snowstorm, i decided to crank to 73 degrees (deviating from my normal 70) The boiler fired, but I felt it did not sound "crisp" as it usually does. I felt something was wrong (sluggish,slow boil) so I decided to read a book in the basement (just in case) To my whopping surprise, the Safety violently engaged (it burned my sheetrock!) I Immediately shut off power to system and now have no heat (with about two feet of snow outside!!)
Two weeks ago, I tightened up the radiators upstairs (some were leaking) I also replaced 1 Vent in 3rd floor bathroom and I put chess pieces in about 3 radiators throughout the house to "hopefully assist in overall system performance.
Did I do something wrong?
Should I even try to fire again?
I am flat broke and there is lots of snow outside..
Should I attempt to clean boiler (It might be dirty, glass seems mildly cloudy)
Is the safety valve still serviceable after popping up once?
