piping madness...or genius?
I am new to central PA and the closest steam heating specialists are ~60mi away and dont seem like they want to come all the way out to my 4500 sq foot victorian (only 3500 ft are heated).
I have decided to replace my ~25-30yr old oil burning utica starfire 226K primarily because of the price of oil which is more than 2x the price of gas (based on eia.gov calculator and gas averages in 2010-2011). My oil cost last year was ~$5800.
I dont know if i TRUST the local HVAC guys to help my one pipe steam system.
I am a DIYer contemplating ordering a Utica PEG225c in 7 sections from Ecoheats.com, hauling it down steps, and reassembling downstairs. Yes, I am aware that steam may be the most difficult heat to control. I had a HVAC guy come today and asked him if my pressertrol which was initially set at 4 was ok for the system, he said "well different systems need different pressures".
I have ordered and I AM reading Dans "the lost art of steam heating" which is fantastic and I though I read numerous times that you are never really supposed to raise the cut in over really 0.5-1psi. This makes me doubt his steam knowledge.
Anyways I have my boiler near piping pics attached. I believe I have a parrallel up system with 2 mains or is it 3? From what I have studied this piping looks a mess.Problems: seemingly MULTIPLE, only 1 riser when there is suppose to be 2, bullnosing, no main vent at the end of the main prior to return, etc.LOOK AT THE PICS ALL TEXT IS ON THE PICS. 3773 and 3783a are probably the best viewpoints. In pic 3774 yellow dot is a main line vent seemingly in wrong area
SO madness or genius? i think madnes, am i wrong? I can provide more pics if needed
