How does a heating boiler work what are the steps in its operating sequence. 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. Too much velocity and the system will not be efficient because of laminar flow issues.

Expansion tank must be rated for use with potable water. Aquastat or system pipe sensor connects to dhw sensor input on boiler. 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. Use either indirect tank sensor or system pipe sensor mounted on common return to the boiler.

Hot water heating systems are built around the premise of radiant heat. However the flow is more balanced and even than the two pipe direct return boiler water loop. This is basically an equalizer to balance the pressure between the two sides of the system. Mixing valves are recommended on all tanks if hot water temperature is above 119of.
