A little update.

This is crazy. Yesterday I was on the phone with Hotmix Italy. So, following their instructions, I put water to the first level of the carafe (1L), selected the first speed and then temperature to 100C. The machined reached 100C. I repeated numerous times and each time took a different time, I supposed if the machine is still hot makes a difference. First time it went to temperature in almost 11 minutes. I also tried with milk. 500 g, reached temperature in 6 minutes and 29. I tried again with the pastry cream. At 25 minutes was still at 65C, I selected 84C.

Also on the other side of the phone were saying that it's crazy. I don't understand how this is possible. Next week we are doing a video call...

 

I'm not sure this is the answer to all of your problems but:

1 Water has the highest specific heat, i.e it will take more calories to raise the temp. 1 degree in water than other liquids such as the fat in milk and pastry cream.

2 If air is incorporated into the liquid as would be more likely in milk and pastry cream it would take even more calories to raise the temp 1 degree, therefore more time.

 

However it should take the same amount of time to raise the temp. 1 degree in the same volume of the same liquid every time.

All of these assume the same starting temp. and volume.
