Set Back or Steam Heat

Pete123 Member Posts: 22
Does it make sense to set back a steam heat system? I set back to 60 degrees at about 10 pm, and for the system to be at 70 degrees when I go downstairs at 7 am. This is also partially due to the fact that it gets too hot upstairs if we don't set back.

But, in general, does this type of set back save money? Or have any other positive or negative affects on the system? THX!

    Usually not.

    The problems that usually arise are excessive noise, spitting vents, etc., but if your system produces good, dry steam, and the pressure is managed such that it cycles at a low pressure while recovering from a setback, I think the only problem you might see is somewhat higher fuel use related to short cycling during recovery, but if your boiler is the right size that might not be too bad.

    If your upstairs is too warm you might consider using thermostatic radiator vents to maintain a more comfortable temperature.
