Claim 14:
15. A method for controlling rate of heat delivery in a hydronic system, the method comprising:
receiving, by a control unit, at least a first temperature and a second temperature from two spatially separated points in the hydronic system, wherein the two spatially separated points correspond to an inlet of a heat transfer device and an outlet of the heat transfer device;
receiving, by the control unit, a flow rate of fluid in the heat transfer device;
calculating at a predefined interval, by the control unit, 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 at the predefined interval, by the control unit, an actual rate of heat delivery to the heat transfer device based, at least in part, on the flow rate and the temperature difference;
determining at the predefined interval, by the control unit, a heat delivery rate difference between the actual rate of heat delivery and a target rate of heat delivery; and
adapting, by the control unit, at least the flow rate of the fluid into the inlet of the heat transfer device and a rate of flow of air in the hydronic system based, at least in part, on the heat delivery rate difference to maintain the target rate of heat delivery in the heat transfer device.
