I have a steam radiator system. My problem is that my pipes that are running from the furnace to the radiators are very hot, however my radiators are not getting hot and the ones that are only half of them are heating up. I have replaced the steam valves, does this take a care of the problem or could there be another way to release the air, or may there be another problem to look for?
If only the bottom half of the radiators are getting hot, you need to bleed the radiators. See previous thread for other problems that can keep radiators cool ( steam traps – banging pipes or some such title)
