Heat pump system with electrolytic biocide-generating unit

A pumping system for use with a heat pump comprising:

• an inlet line that conveys water from a body of water to a heat exchanger where heat is transferred between the water and a 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 water intake includes a tubular intake member having a length that extends between opposite first and second ends, the intake member defining a plurality of water intake openings spaced along the length, the intake member cooperating with the inlet line to define a T-shaped configuration, the recirculation line feeding recirculation water into the intake member through the first and second ends.
