My modern whirlpool electric oven take forever (about 20min) to heat-up to 200C. This seems similar to other electric ovens I have used in Ireland.
Hoever, when visiting my mother in law in the USA, I noticed that her very old(20+ years) electric oven heats up very quickly, about 5 minutes.
Is this rapid heat-up time typical of american ovens or is there something special about hers?
Why does my oven heat-up so slowly in comparison?
