KK, the Strega boiler is similar to the Londinium I in size (around 2lt). The boiler for the Achilles is 4.5lt so possibly it has less impact when the boiler is filled?!? Don't take my word for it, it's only a theory. The pump only fills the boiler with water, there is no pre-fusion by the pump like the Strega. Also these machines can be plumbed and have a drain attached. The set up is rather neat. Under the machine is a switch to turn it from plumb to tank, and to swap it over you would just have to attach a hose & flick the switch. The drip tray has a nut in it, and a hose attaches to a black plastic cup underneath. To return it to tank set up, you just unhook the hose and put the screw back in the driptray hole, and it would then hold water again. Nice feature eh? Its one of the things that sold me on this machine, because I intend to plumb it when I renovate my kitchen, but I can also move it around, use it for small events/fundraisers etc. 🙂
