Hot water heating coil piping diagram.

A one pipe system or monoflo system as it is sometimes called is a distribution system that uses specialized tee fittings to divert a portion of the hot water through a branch piping path. All ball isolation valves are furnished with an adjustable memory stop feature and may be used as a balancing valve. Old unmodified gravity systems are usually direct which means the water from the hot taps and hot water cylinder is the same water that is circulating through the radiators. Hot water heating systems figure below transport heat by circulating heated water to a designated area.

This is a diagram of the obsolete one pipe pumped system. After heat is released the water returns to the boiler to be reheated and recirculated. If a manual or automatic control valve is placed in the branch piping path the water flow through a given heat emitter can be fully controlled. There is no separate header tank and heating coil inside the hwc as in modern systems.

For hot water coils control valves are available normally open.
