: Saturated groups (like those on La Marzocco) are welded directly to the boiler. They generally heat up faster and offer even tighter temperature precision than the E61, though they are often more expensive.
: Thermoblock machines (like many Breville/Sage models) heat water on demand. They are nearly instant but often lack the thermal mass and classic tactile "lever" feel of an E61 machine. E61vs.mp4

The E61 is a heavy brass group head (traditionally weighing about 9 lbs) that uses a thermosyphon system to circulate hot water from the boiler, keeping the brew group at a consistent temperature. It was originally designed by Faema in 1961 and remains a staple in "prosumer" espresso machines. Common Comparison Points
