The radiators in my home are not heating up. I have a 3 floors; the radiators stopped heating on the 3rd floor, now they have stopped on the second floor, and a few have stopped on the main floor. HELP!

The most likely cause is air in the radiators You need to get a radiator bleeding key and open the bleeding screw to let all the air out. With 3 floors you would [robably need to do this a couple of times on each radiator to get any results.
