Steam boilers have small glass windows on them that allow one to check the water level within the steam boiler. Steam heating systems will, by their nature, always lose some of their water with each heating cycle. If there is no water within the boiler, no steam can be produced to heat the house. Check the Low Water Cut-Off Valve
The position set when the boiler was installed is sometimes shown by a red indicator needle. On most digital gauges, you’ll see a flashing pressure reading, if there’s a low (or high) pressure warning. If your boiler pressure reads less than 1 bar, it’s possible that you might have lost water from the system, which needs to be replaced.

You want as little pressure in the system as is possible so the fact you don't see the gauge move, but you get steam to all of the radiators is a GREAT thing. The boiler must be properly sized and working well. The Pressuretrol should actually be a safety devise and should not have to control the pressure in a system that is properly sized.
In fact, many businesses running high-pressure steam boilers could likely satisfy heating needs with low-pressure steam boilers and achieve the same results, while saving on both equipment purchases and operating costs.

Jun 23, 2014 · Why you can't use high-pressure steam boilers on low-pressure steam systems. When the steam's velocity increases (which it surely will when it's at low pressure and aimed at such a little nozzle), the steam will pull the water from the boiler and send it vomiting into the system piping. That causes water hammer,
Steam heating boilers are used to generate steam at low pressures, such as 15 psig. Generally, these two basic heating systems are treated as closed systems, because makeup requirements are usually very low. High-temperature hot water boilers operate at pressures of up to 500 psig, although the usual range is 35-350 psig.
Oct 23, 2018 · But that brings me to boiler-feed pumps. We find these on larger, low-pressure steam systems, particularly those with low-water-content boilers and also on two-pipe steam systems that have steam traps. A low-pressure boiler is one that never goes above 15 psig. And since the folks who make boiler-feed pumps like to have a one-size-fits-all pump, they provide one on all their stock units that will discharge at 20 psig because high pressure goes to low pressure. Always.
In a low-pressure boiler the pressure does not exceed 15 psi, and hot water heating boilers are not designed to exceed over 260 psig. The temperature in a low-pressure boiler will not rise above 250 degrees F.

The system is scalable for larger requirements.
Low pressure boilers lead to fluctuating steam pressure at the kettle leading to a boiler setting of roughly 7-11 PSI. Once the pressure reaches the set point and shuts off when the low point is reached, it must go through the re-light sequence all the while the pressure is falling to an unsuitable pressure causing varying steam pressure thus slower heating and inconstant cooks.
