Story of Chief Big Boiler and Cousin Little Pipe

Details of the system (and previous attempts at fixing things) can be found in the attached thread.



http://www.heatinghelp.com/forum-thread/149174/Complete-System-Review-Two-pipe-System-plus-One-pipe-Counter-Flow-Extension



That said, after performing all of the following:

-capping the return lines which were piped incorrectly,

-skimming the boiler,

-installing main vents,

-replacing & putting multiple vents on some of the radiators,

-adjusting radiator pitch,

-changing some supply valves,

-setting the thermostat's Heat Rate Cycle to 1,

-adding a vaporstat with a low pressure gauge, and (running between .5 - 1.5 for now)

- adding insulation to the near-boiler piping



I have the system to the point where the noise level doesn't startle the neighborhood too much anymore. That said, its not without sacrifices:

- the kitchen radiator still clanks viciously. No effort was able to overcome the mis-sized (3/4") runout to it (... and possibly badly pitched as well). Good thing its furthest room from the bedrooms

- I have to keep the supply valve shut for a bathroom radiator due to the same reason, adding to the oversized boiler issue i have to begin with. (55,410.14 needed vs. 145,000 that the Weil-Mclain EG-50 provides)

- short cycling still occurs, especially during recovery mode since I keep it cold at night.



While i try to find alternate solutions to the short cycling, in regard to the clanking, i read somewhere that, given the narrow size of the pipe, venting the radiator vvvvery slowly theoretically might help a bit. The give & take there is that is a radiator that is further away so if things were ideal, preference would be to vent it a bit quicker.



any thoughts? Given the flaws with the system anything i do is essentially a patch/workaround until i'm prepared to break open the walls and re-pipe.



thanks

    slow might help

    I'd try the slow vents on the clankers, I think the maid o mist #6 is rated for 0.02CFM and you could probably slow it further by partially blocking the hole with a strand of wire. That might mean they don't heat like they should but maybe it will quiet them.



     Next I would stop using a setback and just crack a window in the room you want to stay cool at night. I don't think your saving enough money to matter unless the temperature is turned down for days.

    Setback

    Thank you for the comments. Looking at the setback is certainly a thought. I didn't know enough about the savings to commit to making the change yet. I just posted another thread on the topic. thank you again. I'll follow your advise on the vent ... and let you know.

    ERROR

    In my post above I suggested trying a Maid O Mist #6 because of it's small removable orifice. The #6 is not slow it actually has a 0.15" orifice.



    I meant to tell you to use the Maid O mist #4 which does have the removable 0.028" orifice, the Hoffman 40 has a 0.04" orifice. I'm sorry if this led to any confusion.

  • Banging

    Keeping your supply valves to some radiators closed can cause banging and spiting out of the vents.



    Thanks, Bob Gagnoni
