Summary

Classic designs of ground-coupled heat pump systems (GCHP) use two-pipe distribution networks with variable flow pumping and all of the ancillary water flow control devices. However, a one-pipe central distribution (distributed primary-secondary) loop is a simple system that can save first costs and operating costs. Series-connected heat pumps with a local circulator draw water from the one-pipe loop when their local thermostat calls for either heating or cooling.
