Boiler Steam Control

Steam Heating System Controls amp; Gauges: Photo

The pressure control switch on a steam heating boiler is designed to shut the heating system down should unsafe high pressures develop. As we emphasize at our description of pressure gaugesOn a steam boiler, residential steam heating systems are almost always designed to operate at very low pressures, perhaps around .5 psi - that' s 1/2 of one psi.
