Boiling eggs on an electric or gas stove: why the boiling time difference?
Is there a difference in altitude between where you live now and where you used to live? The heat of a gas and an electric stove should be the same, but boiling temperature differs. The higher the altitude, the lower the boiling point, since it's a factor of air pressure. (More explanations from Wikipedia.)

Water only boils at 100C at sea level. This site can calculate it for you.
