Low Pressure Boilers. Low pressure boilers are tanks or vessels that facilitate the transfer of heat from its source to water or steam at pressures below 15 PSI. Though high temperatures within an enclosed space result in increased pressure, these boilers are able to keep pressure at or below the atmospheric pressure of ~14.7 PSI.

Aug 13, 2015 · Gas-Pressure Switch. Some boilers require gas pressure switches to meet code compliance. The gas pressure switches are to verify that the gas pressure is within a safe range. If the gas pressure is too low or too high, the burner will not operate correctly. Several years ago, a main gas regulator failed in Chicago.

Your boiler's pressure is usually displayed on the boiler's built-in pressure gauge, and should read around the 1 bar mark when you are not running any hot water and the central heating is not turned on. Therefore, 1 bar is a low-pressure setting. Why is my boiler pressure high? Once the boiler begins to heat water, the heated water expands and

Nov 23, 2011 · By definition, a high pressure boiler is one that operates above 15 psi, while a low pressure boiler is one that operates at 15 psi or lower. Steam heating systems run with even lower pressure, typically at less than 1 psi in all. However, these types of boilers are less common (especially in newer homes), and operate using a different system.

A major reason for damages incurred to low-pressure steam boilers is the low water within the boiler. If the condition of low water exists it can seriously weaken the structural members of the boiler, and result in needless inconvenience and cost. Low-pressure boilers can be protected by installing an automatic water level control device.

Based on pressure steam boiler can be classified as high pressure steam boiler and low pressure steam boiler. A high pressure steam boiler is boiler in which steam is generated at pressure exceeding 15 psig and operates hot water boiler above 160 psig or 250o F. Application this type usually is used for utility plants, big industrial plants and process application.
