A heating system and method of using such system in a building for zoned radiant heating. The system includes thermostatic radiator valves, each fluidly connected between at least one radiator in a zone of the building and a boiler. A controller is operatively connected to the valves to deactivate the valve positioners when the controller determines that valve activity is likely to have little to no effect on the output of the respective radiator and/or active heating of the building is not desired. For example, the controller determines when the boiler is deactivated and sends a deactivation control signal to the valves operative to prevent the valve positioners from adjusting the respective valve position. In another example, the controller sends the deactivation control signals to the valves at the onset of preprogrammed low usage periods of the heating system.

Zoned radiant heating system and method

A thermostatic actuator for a radiator valve includes a thermostat mechanism configured to passively open the valve when an environmental temperature is less than a set point and to close the valve when the temperature is greater than the set point. A set point adjustment mechanism draws power from a power supply to selectively drive unitary movement of the thermostat mechanism to adjust the set point. Multiple actuators are used in a zoned radiant heating system in which a controller is operatively connected to the set point adjustment mechanism of each actuator to selectively transmit a control signal to actuate the set point adjustment mechanism to drive unitary movement of the respective thermostat mechanism to adjust the respective set point.
