Your espresso machine is the most expensive thing in the room.
Scale forms fastest where water is heated under pressure, which is exactly what an espresso boiler does all day. A replacement boiler starts around $2,000 in parts and labor, and a burnt heating element runs $200 to $400 before labor. The worst part is not the repair bill. It is the morning you open and the machine does not.
