A step-by-step guide on what should be your boiler’s pressure, is it too high or too low?

What is Boiler Pressure?
It means the pressure at which your heating system operates. The boiler uses a certain amount of pressure to heat the cold water that runs through your house and the radiators’ pipes. It should balance the pressure at an optimum rate, not too low and not too high otherwise, your boiler might lose the pressure or could completely shut down.
