Abstract
A heating fluid control system determines the aggregated demand for heating fluid from a plurality of sources of demand in a building and deactivates a boiler that provides the heating fluid when the aggregated demand is zero. The sources of demand can include radiators and domestic hot water fixtures. Valves that control the flow of heating fluid from the boiler to these sources of demand can transmit signals representative of the position of the valve. A controller can use these signals and other signals to determine the demand for heating fluid from each source of demand. The controller evaluates the signals to determine the aggregate system demand. And after deactivating the boiler, the controller can reactivate the boiler when the aggregate system demand is determined to be non-zero. Methods of using such heating systems are also disclosed.
