Our heating system has had various plumbers shaking their heads - we have a new steam boiler with radiators that have no valves. One guy said the piping was set up for a hot water-gravity system (there are two different diameter pipes for each radiator) and another guy said that the radiators had no valves because they had steam traps built in. We're paying alot for a fairly cold house. We had no heat at all in one quadrant of the house until someone put valves on two of the 11 radiators in the house, and the attic radiators only get warm if its in the 20's for a couple of days. Has anyone heard of steam traps? Or should we put valves on all of the radiators?
