In Reply to: Repiping old steam one pipe system posted by Noah on June 25, 2006 at 21:48:37:
I can actually remove it with a 6 foot lever ( an 1-1/2" or 2" pipe that his about 6 feet long). Put it at the end of your wrench and give it a tug. Since you may be working at funny angles at the ceiling, this may or may not work. If not, the plugs I have removed are hollow. Therefore cut off its face and you should be able to cut it out as if it is pipe in a radiator.
My brother is repiping his two unit house also. After much research and consideration and advice from Heatpro and other experts, he is doing the following : He is putting two condensing boilers in his boiler room at 80K btu each (heatpro says there is no wasteage using 2 small ones vs a bigger one of these). He is then putting an 1-1/4" manifold at the boiler and running up 1/2" pex for each and every radiator in the house. On the manifold are zone valves. He will later decide the placement of thermostats and wire them to the zone valves accordingly. Theoretically, he could put a thermostat in each room.
Heatpro should advise you further if you are interested in this configuration, if you decide to abandon the steam system
