Staeam Heat

Bob_39 Member Posts: 1
I have an old steam heating system one pipe. There is a large radiator on the second floor that takes forever to get hot all the way.What can be done?
Does any one know the size of the vents that go on the pipes in the basement close to the boiler and the vents on the feeders, also does any one know an easy way to get the old ones off.
I read this(There may also be a buildup of sludge in the horizontal runout to the radiator's riser.There may also be a buildup of sludge in the horizontal runout to the radiator's riser. That sludge will trap water, and the water will condense the steam before it reaches the radiator. A "panting" air vent is a good clue that you're having this problem.
)What is the Horizontial Runout? Panting?
Thanks Bobby O.

    This can be fixed

    but you need someone who knows steam. Try the Find a Professional page of this site. If you're in the Baltimore area, e-mail me!

    The "horizontal runout" is the pipe running from the steam main, out to where it rises to the radiator.

    Panting is when an air vent alternately discharges and sucks air in, like a dog does on a hot day.

    Air vents are sized to the amount of air they need to vent and the time frame involved. If you tell us the length and diameter of your mains, also what vents are on them, we can tell you what you need.
