The hob is left to cool for about one hour, to allow it to reach room temperature again.

Another 1 litre water is put in the same pan covered with the same thermometer in it, on the same hob.
Starting temperature of water (and room): 70°F (19°C).
Stage 4 - 9 min.
The heat is switched on. The water reaches 210°F (100°C) in 9 minutes and 27 seconds.
