In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I was reading "The Lost Art of Steam Heating" and there seems to be a discrepancy. One suggestion is to have the steam pressure at a few ounces to overcome the internal friction of the pipes. But it is also written that the steam at the radiator is measured at 1 psi. So the total steam of the system should be 1 psi + the few ounces of internal friction?
