1. A heat pump system for transferring heat using a body of water, the heat pump system comprising:
a heating and cooling loop that directs a working fluid through a heat exchanger where heat is transferred between the working fluid and water from the body of water; and
a water pumping system including:
an inlet line that conveys the water to the heat exchanger where heat is transferred between the water and the working fluid, the inlet line including a water intake at the body of water;
an outlet line that returns the water from the heat exchanger to the body of water;
a pump for moving the water from the body of water through the inlet line, the heat exchanger, and the outlet line;
a biocide generating device positioned along the inlet line for providing real-time generation of biocide in the water flowing through the inlet line; and
a recirculation line for directing water from a tap location on the inlet line positioned downstream from the biocide generating device to the water intake,
wherein the heat pump system is adapted for use in swimming pools or buildings, wherein the water intake includes an intake member defining a plurality of water intake openings, the recirculation line feeding recirculation water to discharge ports provided at the water intake openings.
