    DownFiring One pipe steam

    I took the EDR of my radiation and calculated that my boiler is approximately 60 percent oversized for my load not including the pickup factor. The boiler is a weil and I cannot find a model number on it. It appears to be about 25 years old, one clue to its age might be that it has a weil flame retention burner. My question is would it make sense to downfire the boiler when the tech comes tommorrow? One pipe steam, .5-1.5 lbs, new Gorton #2 vents 95% insulated. Part # the near boiler return and header are not insulated within 4' of the boiler, is it worth insulating? Thanks, Chris

    You can only down fire a small percentage before having problems with combustion, condensation inside, and overall efficiency. Best to leave the nozzle size alone.
