The Lelit Bianca has a normal E61 brew group (the part that sticks out at the front) - i.e. it takes a relatively long time for it to heat up properly. I would calculate 35 minutes.

However, Lelit has a slightly different opinion and gives an "OK" (and the temperature flashes off) in the display quite quickly, i.e. after about 15 minutes or so. But I can still touch the brew group without any problems - i.e. it can't be that hot yet.

But I ordered a timer for it: myStrom WLAN and programme the correct switch-on time every morning. When I'm on the road, I can also switch the machine on/off with my mobile phone and can thus switch it on while I'm shopping in the supermarket on Saturday so that it's properly heated when I get home.

I'm very happy with the Bianca - it's fun to make espresso with it!

Kussmaul is basically right about E61 brew groups - but the Bianca is actually temperature-stable after 20 minutes when both boilers are active. Waiting longer and/or using a timer is certainly better, but after 20 minutes you can make a brew.
