Abstract: A heat control system designed to control individual radiators in a heating system where there is only one boiler supplying steam, or one heated fluid source such as a utility steam supply, and where there is no separate condensate return line; each radiator or riser or both may be individually controlled by devices at and external of the radiator without the need for reconstructing the heating system itself or inserting any mechanical device within the system which will block return of condensates; there is an on-off control valve between the radiator and its vent valve and controllable preferably by a room thermostat; additional fuel saving controls may include a device that is responsive to the radiator becoming heated to a desired level or internal pressure in the radiator to provide an additional control for the control valve.
