1. One-pipe hydronic heating control device comprising:
a secondary supply pipe connection on an inlet pipe of an exchanger;
a secondary return pipe connection on a return pipe of the exchanger;
a primary inlet pipe connection on a primary inlet pipe from a heat source and a primary outlet pipe connection on a primary outlet pipe to the heat source; and
a pump impeller provided with a control unit to pump heat-transfer medium,
wherein a first T-branch, which is connected to a second T-branch interconnected through a primary outlet, is connected to the primary inlet pipe connection through a primary inlet pipe,
wherein a first T-branch is connected to the secondary supply pipe connection through a secondary supply pipe with a secondary supply temperature sensor,
wherein the second T-branch, which is connected to the primary outlet, is connected to the secondary return pipe connection through a secondary return pipe with a secondary return temperature sensor and the pump impeller is connected to the secondary circuit such that it pumps the heat-transfer medium from the first T-branch through the heat exchanger back to the second T-branch,
wherein the hydraulic resistance of the connection is negligible with respect to the hydraulic resistance of the inner primary inlet pipe, and
wherein the pump impeller is connected to an electric motor, the electric motor is interconnected to and controlled by the control unit, and the control unit is interconnected with the secondary supply temperature sensor and/or the primary inlet temperature sensor and the secondary return temperature sensor.
