Classification: CPC F  G | IPC F  G

Claim 9:
10. A hydronic system, comprising:
a heat transfer device;
a forced air heat delivery component configured to control flow of air in the hydronic system;
at least one pump operatively coupled to a storage tank for pumping fluid from the storage tank to the heat transfer device; and
a control unit operatively coupled to the heat transfer device, a forced air heat delivery component, and the at least one pump, wherein the control unit is configured to perform the following steps at predefined intervals:
receiving at least a first temperature and a second temperature from two spatially separated points in the hydronic system, wherein the first temperature corresponds to temperature of the fluid entering an inlet of the heat transfer device and the second temperature corresponds to temperature of the fluid leaving an outlet of the heat transfer device;
receiving a flow rate of the fluid in the heat transfer device;
calculating a temperature difference between the two spatially separated points in the hydronic system based, at least in part on, the first temperature and the second temperature;
calculating an actual rate of heat delivery in the heat transfer device based, at least in part, on the flow rate and the temperature difference;
determining a heat delivery rate difference between the actual rate of heat delivery and a target rate of heat delivery;
calculating a target pumping rate based, at least in part, on the heat delivery rate difference; and
maintaining the target rate of heat delivery in the heat transfer device by:
operating the at least one pump at the target pumping rate for adapting at least the flow rate of the fluid into the inlet of the heat transfer device; and
operating the forced air heat delivery component for adapting a rate of the flow of air in the hydronic system.
