The radiators, preferably of the hot-water type, must have considerably more surface than with low-pres-sure steam heating. A special valve is placed at the supply end of eachradiator, designed to admit any desired volume of steam. A little trap or water-seal fitting isconnected with the return end of eachradiator, a small hole being providedabove the water line to permit the escapeof air. All returns are joined in thebasemenl and discharge to an open watercolumn alongside the boiler, any steam inthe returns being condensed by passinginto a coil provided for the purpose.
