A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
Dec 10, 2018 · The advantage of a semi-automatic or automatic pump-driven machine is control with consistency. This is why high-end pump machines usually have multiple boilers. They allow the brewing water to be heated separately from that used to create steam. This allows better temperature control and reduces the chance of over-extraction.

Nov 15, 2018 · Most semi-automatic machines will have an on/off switch or button, then some way to control whether you are brewing, steaming, or both. Be on the lookout for indicator lights as well. This shows you that the water has reached proper temperature so you know when it's okay to brew or steam. Amount of control
The master-slave function may be disconnected and allow the boilers to operate independently. At inert gas firing the master burner's load is limited to operate between 50% and 100%. A steam dump controller should automatically take over the steam pressure control and by means of a control valve dump the excess steam to a steam dump condenser.
There are just three buttons on the control panel, one for power, one for espresso and one for froth/steam functions. A large rotary dial on the right allows you to fine tune the pressure of the steam and a couple of LED lights indicate the power supply and whether the machine is brew ready.
