Old cheaper Main vent valves.

So I have a new Utica gas steam boiler with the older cheaper vent valves on the Mains and i was wondering if I went with a Gordon #1 if there would be any difference in the way the radiators heat up. The system right now works very good.

    it depends. look at how long it takes for the ends of the mains to get hot from when the boiler starts steaming. if it is a couple minutes then the limiting factor is probably the mass of the mains. if it is like 10 minutes plus then you could probably use more venting.

    also make sure they close when they see steam.

    @roadmaster , how long are the mains and what pipe size? What vents are on them now?

    The two mains are 20' in length each. They are 2" black pipe. The air vents are maid of mist. I have read some good reviews on the Gordon #1 vent valves. Thanks

    The Gorton #1 would be a good choice for those mains.

    Before you spend the money to replace the existing main air vents, you should pull them off and try to blow through them. If you can blow through them smoothly, and they're not leaking Steam, then there is no reason to replace them. The mom number one and the Gorton #1 have the same capacity. Which MOM do you currently have?
