High Pressure vs. Low Pressure Boiler

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.

Boiler Pressure Too High? Heres Why, And How To Fix It

The first and most obvious problem that leads to high boiler pressure, is a heating system that has been overfilled. By topping up water via the external filling loop, you can add pressure to your boiler. Your boiler needs sufficient water in it to operate correctly.

This pressure is measured in terms of pounds per square inch or psi, and gauge pressure is expressed as psig. The National Fire Prevention Association and federal standards define a Type II steam boiler as one that produces high-pressure steam between 16 and 150 psig. A Type III steam boiler produces steam between 151 and 350 psig.

Why you can't use high-pressure steam boilers on low

Jun 23, 2014 · This is why you can't run a high-pressure boiler on low-pressure settings. The boiler manufacturer told the contractor about this when the contractor called to ask. The contractor thought he could get around the high-velocity problem by cutting into the boiler and welding a bigger nozzle onto the shell. The boiler manufacturer said this would probably work, but the contractor hadn't mentioned the
