one \"slow\" radiator

Steamhead (in transit)

are the first two things to do. Is the problem radiator toward the end of the main?

Hi All,

I have a steam/one-pipe system and one radiator on the second floor seems to be "slower" than others. When other two on the same floor are hot, this one makes very weak hissing and is barely warm.

Eventually, thermostat on the first floor shuts off the furnace and the cycle ends - my radiator is just slightly warm. When I try to prolong the cycle by increasing the thermostat setting by a few degrees, the radiator becomes hot and nice, although it still takes longer then any other.

I went thru a checklist: replaced the air valve, service valve is fully open and seems to be ok, the radiator is tilted - no results.

Is there any way to have the thermostat to make longer cycles to overcome this? Any other feedback is appreciated. I could see some potential improvements, like venting and insulating the main in the basement, but, overall, everything works fine for me, except this one radiator, that is also unfortunately in our bedroom.

Thanks,
Eugene

Insulate and vent the main

measure the length and diameter of the main (and any other mains you may have) and we can tell you what vents you need.

For insulation, fiberglass pipe insulation with 1" thick walls is the right stuff. The cheap foam you buy at home centers will just melt off.
