Heat is released from the water as it flows through the heating unit coil terminal. Hot water heating systems figure below transport heat by circulating heated water to a designated area.

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. 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. For hot water coils control valves are available normally open. All ball isolation valves are furnished with an adjustable memory stop feature and may be used as a balancing valve.

After heat is released the water returns to the boiler to be reheated and recirculated.
