Venting is limited to a small amount of the entire H2O and steam volume inside the piping and radiators but does need to be replaced. Most of the steam condenses and is returned to the boiler through the return piping system either by gravity or a condensate pump. As the system uses steam it vents the condensation or steam and this displaces water from the steam system that needs to be replaced and the replacement H2O comes from a make-up water source.

The average residential/light commercial boiler typically uses different controls to sequence the boiler. Boiler control in commercial and industrial applications can be very complex and can have added layers of controls outside of the local boiler controls that come from the manufacturer. There are also differences of the controls between steam and hot water boilers. Breaking all this down into sections we’ll be as concise and detailed as possible while using brevity to describe residential/light commercial boiler control and cover commercial/industrial boiler control in another article. Some of this information will overlap but rest assured we’ll be as detailed as possible.
