Two pipe system HELP >> no traps or vacum pump

Tom_24

I am managing two 1930 Manhattan residential buildings. Both 13-story buildings are steam heated with its own separate oil (No4) boilers in very good shape. The problem is that the steam is being pushed into the building until the entire system is pressurized. Some minor water –hammering and under heating (last raiser) is present. My proposal to the buildings is that they install traps on every radiator and while at it, possibly install individual thermostatic valves to control every room temperature. In addition, I think that the FT traps are needed for each riser.

The question: is there a way to estimate possible saving on heat? My estimation depending on the elimination of current return line heating (without the traps) and uncontrolled heating (overheating) the project could save 30%-40%. Is there anyone who can actually calculate the saving and give me a report in writing? Then, what is the cost of such project? The radiators have plenty of room under them to install the trap and enough room to install the thermostatic valve as well. There are in around 160 radiators per building. If there is anyone that would be interested to come and see it in person, please call me for a appointment (212) 737-0910 and ask for Tom and tell whoever picks up that you call regarding the steam heating upgrade. . Thank you in advance!
