New Boiler - Hammering and Leaky Air Vents
I finally bit the bullet and converted my steam system from oil to gas about 6 weeks ago. The first few times that the heat came up everything was fine. Then I started to get very loud hammering all throughout the house. The hammering is primarily at the beginning of the cycle. A few days after the hammering started, water started to leak from the air vent on a radiator in the basement. That was followed by the same thing happening on a radiator on the first floor. That was the status for a couple of weeks and now another radiator on the first floor is leaking water from the air vent (so far no leaks on the second floor). I swapped a new vent on one of the radiators (a Durst A884 that I got at Lowes) and it leaked right away, so I don’t think there was a clog in the old vent. I did not have any leaks or hammering with my old oil boiler.
My boiler is a Williamson GSA-200-N-I. The PSI is set to .5. In case it means anything, the water feeder counter was ticking up once for roughly every 3 cycles for the first few weeks. Now, it’s only every 5 cycles or so.
I’m including pictures of the boiler and the leaking vents. Any thoughts on why this is happening and what I can do? The plumber who installed the boiler is blaming the pitch of my pipes and my air vents. He says the new system makes the water hotter than the old one. Did he do something wrong? I didn't expect that getting a new boiler would mean I would need major plumbing work throughout the house.
