Pressure. Residential steam boilers operate under very low-pressure conditions. However, a large volume of low-pressure steam can be a danger. For this reason, there are pressure controls on the boiler. Normally set at 2 P.S.I., the pressure control will shut down the system if too much pressure is sensed by the pressure control.
