Warm-up simulation of a greatly simplified E61 group head. The thermosyphon pipes are connected to the brew boiler. Inside the boiler is an ‘invisible’ heater with a power of 1.2kW. At the beginning of the simulations everything is cold, and over time the warm water starts to heat up the brass group
