A closed loop, pressurized system for a ground source heat pump and a pressure/liquid source module therefore. The pressure/liquid source module has a liquid tank having a predetermined liquid level and an inlet pipe extending downwardly within the tank from adjacent the top of the tank to a distal end which is below the liquid level. The inlet pipe is adapted to be connected to the loop of the closed loop, pressurized system of the heat pump. The liquid tank has an outlet adjacent the bottom of the tank, the outlet being connected to the heat pump through a check valve and a liquid pump. The valve is between the tank and the pump.
