1. A pump assembly for a hydronic heating system, the pump assembly comprising:

  • a permanent magnet motor having a stator with coil windings;

    a rotor assembly having a shaft and an impeller attached to the shaft, the shaft being driven by the stator, the impeller driving fluid through the pump assembly;

    a pump housing holding the permanent magnet motor and the rotor assembly the pump housing having a suction end configured to be coupled to a supply pipe of the hydronic heating system and the pump housing having a discharge end configured to be coupled to a discharge pipe of the hydronic heating system, the impeller moves the fluid of the hydronic heating system to pump fluid through the hydronic heating system; and

    a control module mounted to the pump housing, the control module having a controller and a user interface, the controller measuring operating characteristics of at least one of the motor and the stator, the controller determining at least one of the flow rate and the pressure of the fluid moved through the pump assembly based on the operating characteristics measured of at least one of the motor and the stator, and the controller controlling power supply to the coil windings based on the operating characteristics measured of at least one of the motor and the stator, and the user interface being accessible at an exterior of the pump housing, the user interface being configured to display an output representative of at least one of the flow rate and the pressure of the fluid determined by the controller based on the measured operating characteristics of at least one of the motor and the stator.
