Most often because they become air/water-locked. A cast iron radiator system works by sending steam (which naturally rises) up from the lower level into each radiator. When the steam heats the cast iron it loses enough heat so that it cools back to a water (liquid) state. When this happens, the water must flow back to the burner all by itself, propelled ONLY BY GRAVITY. So if at any point in the loop ANY length of pipe has sagged so that it is not downhill enough to allow the water to drain, the system will become locked at that point and no steam will pass by, thus cutting off heat to all radiators beyond the blockage. The most common fix for this is putting shims underneath the feet of the radiator on the opposite side of the pipe only, thus angling the radiator down for full drainage. Many times people will cause the issue themselves by putting a floor or tile underneath the radiator, inadvertently removing the angle. Other times, the natural sagging of the house removes the angle put in when the system was originally installed. So, your best bet is to 1.) Shim all non-working radiators downward toward the pipe, 2.) Drain the whole system (from the spigot at the base of the burner) of all water (and air), and 3.) re-fill the burner with water to the appropriate water pressure. Replacing the steam valves on each non-working radiator is a good idea as well.
on sims 2 pets you dont have any upstairs or any stairs at all
i dont think so
They have heaters and we dont
i think that they would probably not work without the sun and in addition to this i dont think they would make us much heat as the other heaters eg convectional heaters

Bottom corner of the radiator, facing the engine, typically opposite end of the radiator from the lower radiator hose.
its there....i think its a screw on the very bottom of the radiator..faces the ground if you dont see one disconnect the lower radiator hose
dont sit on it all day and do some frickingexcersise
