  • Steam Air Vents

    Steam Air Vents

    Radiator steam air vents are used on heating systems that utilize steam as the primary heating source. They come in differing orifices depending on the distance away from the boiler. Smaller orifice air vents are generally closer to the boiler with larger orifices used further away. This ensures that radiators further away from the boiler receive enough steam to get hot. Steam air vents also close so the branch to radiator will stop flowing steam. If your steam heating system will not shut down then checking to see if an air vent is closing properly should be the first place to look. If air vents are not closing the boiler will not reach it's working pressure and will not turn off. Main steam air vents are located in the basement and also control the flow of steam to the steam branch line.

  • Hydronic Air Vents

    Hydronic Air Vents

    Hydronic air vents are used on heating systems that utilize hot water as the primary heating source. They are used to bleed air out of the heating line so the hot water flows smoothly through the heating system. If some of the radiators on second or third floors will not get hot after bleeding they are probably still air bound. In this intsance you need to temporarily raise the pressure in the heating system to force that air out. Once water comes out without air you can then lower the pressure back to normal operating pressure.
