Hi Kitt I think that it is a pretty well know fact that the Brewtus is down on steaming power when compared to other similar machines on the standard water heating test. According to the reviews on Home Barista of the Brewtus, it is around 33% slower than other machines in the same sort of price range, namely La Spaziale VII 1.2mm Tip, Vibiemme Domobar Super, Quickmill Andreja Premium or Giotto Premium who all seem to take around 28 seconds to raise a 8oz of water from 40 to 160 degrees Fahrenheit vs the Brewtus which takes 38 seconds with the two hole tip and 60 seconds with the single hole tip. Home Barista even mention in the conclusion of their review of the Brewtus "However, both the single and two-hole tips fell short of the steaming power one would expect from a machine with a dedicated steam boiler."
Now whilst steam speed is not everything and sometimes a bit slower makes it easier, there are times when I would appreciate a machine that can heat a jug in 28 seconds rather than 60 seconds (like when I have to make coffee for the whole family). I have owned both a Brewtus III and now Brewtus Rotary for the last 5 years love the machines. I did noticed a slight increase in steam performance between the two when I upgraded. It is however no where close to what I get from a GS3 (haven't taken that step yet, still considering). I know that the machines are not in the same price range but I would hope that the Brewtus's steam would be slightly better than it is. I have played around with steam tips using an 8mm to 10mm converter and various steam tip. I have found that the machine simply cannot deliver enough steam to power a tip with 4 holes properly. I believe/hope that it is not because it doesn't have enough steam but I suspect rather because the steam arm is restricting the flow of steam from the boiler. My aim is to try changing the arm to a standard arm to see if it can drive a 4 hole tip with enough steam to be able to produce microfoam (just not possible with current arm). I will also measure the time it takes to heat water as a comparison.
