Typically boiler pressure should sit somewhere between 1 and 2. However, you should consult the manufacturer's instructions to find the appropriate pressure for your boiler. All boilers will very gradually lose boiler pressure over time but a sudden sharp drop could be the sign of a bigger issue.
ZOZEN Boiler-A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil.
2019-7-12 · The percentage of total heat exported by outlet steam in the total heat supplied by the fuel (coal) is called steam boiler Efficiency. Includes with thermal Efficiency, Combustion Efficiency & fuel to steam efficiency. Steam boiler efficiency depends upon the size of boiler uses. A typical efficiency of steam boiler is 80% to 88%.
2011-3-28 · (c) Increasing the boiler pressure (Increases T high, av). Lowering the Condenser Pressure (Lowers T low, av) Steam exists as a saturated mixture in the condenser at the saturation temperature corresponding to the pressure inside the condenser. Therefore, lowering the operating pressure of the condenser automatically lower the

A combi boiler pressure gauge reading over the 1.5 mark whilst the heating is in full operation, is likely normal due to the water demand being placed on the boiler so it's likely nothing to worry about. In this instance, a reading between 1.5 – 2.5 bar can be considered normal.
Feel free to ask your boiler engineer to check the boiler's pressure during the next service. However, small rises in pressure are normal. Once the pressure rise becomes 0.5 bar or more, that usually signifies that there's a problem with high pressure. #3 – Boiler Pressure Rises (MORE Than 0.3 Bar When Heating/Hot Water Is On)
