How long does it take to heat up a manual coffee machine?
I'm often asked about heat up time. Traditional HX and DB Italian coffee machines have an e61 group (the Star Trek looking thingy out front). The boilers in these machines heat right up in about 5 minutes, but allow another 20 minutes for the e61 group to reach thermal equilibrium before pulling your shot.
Of course, if you are in a big rush you can run heating water through the e61 group, then pull a decent shot just 10 minutes after switching on. I often do this myself.
Never give up an e61 group head to for the sake of saving a few minutes during heat up. The e61 is legendary for good reasons including thermal stability and gentle pressure ramp up during brewing.
I suggest picking up a $20 power point timer to switch the machine on just before wake up. That's all you need.
