    Hell, I must have dementia. Did I say my machine has a 10 litre boiler? Halve it. 4.9 litres.

    EspressoAdventure: Bite your tongue. 1.3 litres...in my garage? Never. That few cubes amount to 2 cylinders worth of my 5 litre Ford V8s...and even less of my 6.4 litre Chrysler hemi. 0-100 in 4.something seconds without strain.

      BTW an E61 grouphead has less thermal mass than 400 ml of water

      Sorry if I got lost somewhere, but where did 400 mL of water come into the equation? Water flowing at a <2 mL/s for ~30 s?

      I think the intricacies of cooling flushes are going to have more serious implications for brew temp (for most HXs, anyway), the location on the pstat cycle won't be noticeable.
