La Marzocco Micra is up to temp in under 10 minutes and will stay there all day, it works very well indeed.

Do you know what is it that it allows for such a quick warm up? Small boiler? Saturated group? Maybe my comment is more relatable to HX machines then although I don't quite get how is it possible to warm up so quickly - the machine is still a 20kg piece and you can't beat physics with such large thermal mass.

		250ml brew boiler with a small saturated group, and a separate 1.6L steam boiler. It's definitely aimed at a home environment but will easily keep up with making several drinks in a row. Compared to previous HX machines I've owned, it heats up much quicker and is more stable. I think not having a massive lump of brass like an E61 style machine helps a lot.

		They have separate tanks for keeping water heated up to temperature wit a much smaller volume and don’t use saturated groups so the total hot mass is much smaller.
