I just moved into a house built in 1922. Old-style radiators everywhere. No matter how high I turn the thermostat, the radiators stay warm to the touch! There's a knob at the bottom of each radiator, but none will turn. In either direction. HELP!!

Tongue-in-cheek as it might be, I'd say hunt down a couple of the new oil-filled electric radiant heaters... or if the expense isnt an issue, have the system thoroughly serviced or replaced. My home has a natural-gas furnace but I also have gas jets in every room of the house and gas heaters to use with them if the need arises, and it has worked very nicely as a backup. (Another option, perhaps?)

If your system is steam, make sure that all the steam vent on the end of each radiator is hissing. I would think that the valves are already open do check this first. Lo pressure steam boilers for residential usually run at about 1 to 2 psi. adjustable steam vents are availiable and can be adjusted to vent quickly or slowly. Closest to the boiler, set to higher #'s 1-9. these will vent slow. Further away, set to a low # to vent quickly and deliver heat.

If your radiators have 2 pipe connections, then the problem sounds as though the steam is pushing the air in front of it, but the air has no where to go. The system should heat the home with stellar comfort and do so with little noise. good luck, Tim

If the knobs at the bottom of the radiators won't turn in EITHER direction, then it could be that they are partially shut off, and nothing will make the rediator heat up completely until the valve is opened. You ought to get those knobs working.
