What is important choosing the right heating element for my coffee machine?

Well first of all the heating element flange, seen those are in most cases not interchangeable with each other. seen a Cimbali heating element won’t fit a Nuova Simonelli heating element due to the flange model. A other important feature is the length of the heating element. When it is too long, it won’t fit. When the element is too short you will get uneven heat distribution in the boiler.
