Imagine. Its a hot day. You have too much heat. You are standing at the bus stop, someone gets up and you take their seat. They have heated up the seat with their bum, but when you sit down you dont find their heat unpleasant - even though you have too much of your own. If you found that person attractive, you even like their heat (but you would never tell anyone).
This is because their heat is a frequency that you dont have much of. Heat is part of the electromagnetic spectrum. The visible part has colors for different frequencies. Heat also has a spectrum (infra-red). Different people (and things) generate different frequencies of heat, due to differences in personality, genetics, diet, activity, etc. Everyone has their own unique pattern of heat, and it can change quickly and easily.
Heat from combustion and electric resistance are different from each other. So, cooking on gas tastes different than cooking on an electric element, or a microwave oven, because different frequencies of heat enter the food, resulting in slight differences in the chemical reactions that are the cooking process. No need to think you are crazy because you dont like the taste of things cooked in the microwave! Heat from a fire matches our combustion heat, so it either feels nice if we are cold. Not all heat is the same.
