Two-pipe system may be direct-return (return main flow direction is opposite supply main flow) or reverse-return (return main flow is the same direction as supply flow; after the last unit is fed, the return main returns all water to the boiler). The direct-return system is popular because less main pipe length is required; however circuit balancing valves usually are required on units or sub- circuits.
