Boiler - an overview | ScienceDirect Topics
Boiler banks transfer heat from flue gas to evaporate the steam-water mixture. A two-drum boiler bank was very typical in early boilers and is still used in smaller, low-pressure boilers. In small biomass BFB boilers one can often find a boiler bank (i.e., an evaporative heat transfer surface).

Boiler Pressure and Central Heating System Pressure -- Why
Where an external expansion vessel is fitted, and the cold boiler pressure is 1 bar, you may see a rapid rise in boiler pressure as the system heats up. This is because, with a pre-charge pressure of 1½ bar, the expansion pocket in the external vessel is only available once the boiler pressure reaches 1½ bar.

The National Board of Boiler and Pressure Vessel Inspectors
"Operate the boiler at its maximum design pressure" is a common saying among boiler designers. But too often, this rule is not followed when energy cost reductions are needed. During periods of low steam demand, or when all the use points require pressure-reducing stations, boilers are often operated at substantially less than design pressure.

Why Does My Boiler Make A Banging Noise When Firing Up
Delayed ignition is a problem that's common in gas boilers that use pilot lights (as opposed to electronic ignition systems). You see, during normal operation, when a gas boiler receives the call for heat, the gas valve opens and releases a small amount of gas into a sealed combustion chamber via small "jets".

Ideal boiler pressure should sit around the 1.5 bar mark, you can check this by taking a look at the built-in pressure gauge. Over time, an Ideal boiler will very gradually reduce pressure but if there's a sudden drop in pressure it's likely that it will be down to a leak in the system or the radiators having recently been bled.
